Two case studies of recent (ideally within the last 30 years) seismic events should be undertaken from contrasting areas of the world. In each case, the following should be examined: • the nature of the seismic hazard; • the impact of the event; • management of the hazard and responses to the event. Contents 8 OCR A2 Geography: Global issues What are the hazards associated with earthquake and volcanic activity? Earthquakes and volcanic eruptions are caused by plate tectonics and bring distinctive impacts to an area and these vary from place to place. Earthquakes and volcanic eruptions have a range of environmental and social impacts on the areas affected, which create a range of human responses to the hazard. The study of an earthquake and of a volcanic eruption to illustrate the: • tectonic processes involved in creating these hazards; • scale and types of impacts (environmental, social and economic), together with the concept of primary (initial impacts – destruction, casualties, landslides, fires) and secondary impacts (including disease, infrastructure problems, resettlement); • human reaction in both the short term (emergency rescue) and long term (planning & management). Why do the impacts on human activity of such hazards vary over time and location? The degree of impact on an area reflects its level of economic and technological development as well as the population density. Impacts can vary over time from immediate to long term. The study of contrasting examples to illustrate a: • contrast between countries at either end of the development continuum and between rural and urban areas, to compare the impacts of, and reactions to, at least two contrasting types of earth hazards; • comparison of impacts over short and long time periods for at least two contrasting types of earth hazards. Contents 9 OCR A2 Geography: Global issues How can hazards be managed to reduce their impacts? There are various ways to manage or reduce the impacts of hazards. The study of different approaches to managing earth hazards to illustrate: • the extent to which earth hazards are predictable; • the management strategies used to reduce the possible impact of a hazard; • the effectiveness of managing earth hazards. Key Concepts: • • • • • • • The nature of hazards varies with location. The nature of hazards changes over time and space. Earth hazards consist of a variety of interdependent and interconnected activities and processes. Physical geography and human activity are interdependent and their interaction can produce hazards. The impact of such hazards varies over time and given location. Populations and environments respond in a variety of ways to hazards. The management of hazards results in opportunities and challenges. Associated Skills: • • • • • Research into hazard events Analysis of a variety of types of image Map work at a variety of scales, eg hazard mapping Statistical analysis, eg analysing patterns and severity of hazard Use and application of GIS and other modern technology, eg forecasting of earthquakes and eruptions Contents 10 Assessment objectives .You will need to: A01 Demonstrate knowledge and understanding of the content, concepts and processes.

Start an “Earthquakes” folder for your research and case studies. 2. Throughout your study extract the key information about the tectonic event and retain the findings and maps in your folder. This will help you justify your choice of case studies. 3. Remember to add references (sources) for the work of others and to add definitions for key terms by compiling a glossary of definitions in your folder. Contents 17 Case studies in this presentation The Haiti Earthquake (2010) and Tohoku, Japan Earthquake and Tsunami (2011) will be the main point of comparison in your research. Earthquakes such as Sichuan, China (2008), L’Aquila, Italy (2009) and Van, Turkey (2011) also feature. In this presentation exemplar slides in the introduction and information for your research in subsequent sections will guide you through the process, leaving the active research and case studies to you.

How does the author’s role or job such as academic, lobbyist, businessman, politician relate to the topic? Consider North Korea and Amnesty International presenting on the same issue, for example. • Is it a primary or secondary source? How reliable is it? • Does the website verify what it publishes or is it an open forum where anything can be posted? Who owns and contributes to it? • Is the information up to date? Contents 22 Question statistics • Who collected the numbers? Using what method and for what reason? • Simply because they are published doesn’t make them facts. Many are actually estimates. • Location matters. Collecting statistics in remote rural areas of developing countries or densely populated urban settlements, for example, can be difficult if they have been collected at all. A hazard or disaster event adds complexity. • Numbers can be political. There may advantages to overstating or understating numbers. • Statistics need to be collected in the same way to be compared.

In the cluster, there were 3 earthquakes greater than magnitude 6 before the main shock and another 14 in the first 6 hours after. The aftershocks intensity decreased with time since the main shock and followed a predictable pattern.

A hazard involves people. • “A disaster is an occurrence disrupting the normal conditions of existence and causing a level of suffering that exceeds the capacity of adjustment of the affected community.”(WHO/EHA 2002). There is no universally agreed numerical threshold for designating a hazard as a disaster. A matter of scale, a disaster is a lot bigger than a natural hazard. • Capacity: A combination of all the strengths and resources available within a community, society or organization that can reduce the level of risk, or the effects of a disaster.

Based on the video make a mind map about why the Haiti earthquake lead to disaster. See sample mind map for guidance. Source: http://www.mind-mapping.co.uk/make-mind-map.htm Contents 45 What is a tectonic event? • A tectonic event is a physical occurrence resulting from the movement or deformation of the Earth’s crust. • Tectonic events are predominantly earthquakes or volcanic eruptions. • Tectonic events become tectonic hazards when they have the potential to cause loss of life and damage to property. • Not all tectonic events are hazardous. Contents 46 Tectonic hazards Tectonic activity cause a very large range of hazard events. These are associated with the processes of earth movement and volcanism, and they are classified into primary and secondary hazards. Primary tectonic hazards include earthquakes, volcanic eruptions, pyroclastic flow, ash fall and volcanic gases. Secondary tectonic hazards include tsunamis, landslides and lahars. A tsunami is a secondary hazard, because the flooding is caused by the earthquake at sea. Tsunamis like the Asian Tsunami (2004) are rare. Contents 47 What is an earthquake and tsunami?

The main shock in a cluster is the one with the largest magnitude. Foreshocks occur before the main shock. Not all main shocks have foreshocks. The main shock is always followed by aftershocks, which are smaller than the main shock and can continue for weeks, months or years. Each earthquake can provide new information: • If a subsequent event is larger than the one deemed a main shock, it can be redefined as a foreshock, for example, Tohoku, Japan (2011). • Similarly, an aftershock may sometimes be reclassified as a foreshock. Contents 49 Tohoku Japan (2011): Foreshocks, Main Shock and Aftershocks Foreshock: 11.45 (2011-03-11) Magnitude: 7.3 Aftershock: 23.32 (2011-04-07) Magnitude: 7.2 Main Shock: 14.46 Magnitude: 8.4 Aftershock:17.16 (2011-04-11) Magnitude: 6.6 Aftershock: 15.08 Magnitude: 7.4 Aftershock: 14.07 (2011-04-12) Magnitude: 6.4 Aftershock: 15.15 Magnitude: 7.6 Aftershock: 15.25 Magnitude: 7.5 Aftershock: 09.57 (2011-07-10) Magnitude: 7.3 oclockpress.com 50 Foreshocks, Main shocks and aftershocks sequence • . Tohoku, Japan (2011) Map: 11 March - magnitude 9.0 main shock off Tohoku followed by 166 aftershocks of magnitude 5.5 and greater until May 20. Aftershocks follow a statistically predictable manner. In common with almost all of the largest earthquakes, this one is on a subduction zone. Warmer colour for more recent events Larger symbol for greater quake magnitude. Action for students: Record in your glossary what is meant by a subduction zone . Explain why it causes 5000 earthquakes a year in Japan (one or more a day). Source: USGS Contents 51 Seismic waves Action for students: 1. • • • • • • • Correctly label the image: Surface waves Rayleigh wave Love wave Body waves P waves S waves Elliptical motion 2. • • Answer the questions about Love, P, S and Surface waves: Which type of seismic wave travels fastest? Which type causes rock particles to move together and apart in the same direction? 3. In order to determine how far from a seismograph station an earthquake occurred, one needs to look at the difference between: Seismic waves and elliptical motion P & S waves S & Love waves P & love waves • • • • 4. • • • • Which one does not control the level of shaking: Distance Weather Local Soils Magnitude Source: http://earthquake.usgs.gov/learn/glossary/?term=S wave Contents 52 Measuring shaking Seismologists use a seismograph: an instrument that registers the movement of the Earth's tectonic plates caused by seismic waves and produces seismograms such as this USGS one: A short wiggly line that doesn’t wiggle very much means a small earthquake, and a long wiggly line A long wiggly line (seismic wave) that wiggles a lot denotes a large earthquake; a short one that doesn’t wiggle a lot a small one. The length of the wiggle depends on the size of the fault and the size of the wiggle by the amount of slip. At least three seismographs are needed to triangulate the location of an earthquake. Measurements are on the logarithmic Richter scale from 1 – 10 with decimals.

Ground shaking Ground shaking is most direct effect with cracks in land and structures, falling masonry and / or collapse. animation: http://earthquake.usgs.gov/regional/nca/simulations/ Secondary effects occur as a result of the primary effects, for example, fires due to ruptured gas mains. Ground displacement may not be life threatening; however, it impacts on buildings, bridges and roads. Landslides are movements of masses of rock or debris down a slope. Slope failure can be triggered by, for example, earth tremors. Photo: http://earthquake.usgs.gov/learn/glossary/?term=landslide Liquefaction occurs when the shaking of silts, sands and gravels causes them to lose their load bearing capacity. Buildings and other structures, may thus sink into the ground.

Learning outcome By the end of this section, you should be aware of the effects of earthquakes on the landscape.* Contents 64 Haiti before and after the earthquake Juvenat: August 3, 2009 Further info on Haiti before 2010 in Appendix Juvenat: February 13, 2010 Source: http://gfdrr.org/docs/Haiti_MultiHazard_RiskAssessment_Report_EN.pdf Contents 65 Geological records • Historic records of earthquakes can be incomplete and some countries have longer records than others. • Where there are no written records of earthquakes geological and soil maps can be used to identify past earthquake activity. • The geological record when understood can enable areas of high risk to be mapped. Contents 66 Event Profiles Event profiles can be drawn for any event and help illustrate the great variation in the nature of tectonic hazards. They are a common way to compare and contrast different hazards. The typical earthquake and volcanic profiles tend to differ most in terms of spatial predictability and frequency. This profile compares factors of the Asian Tsunami (2004) with the continuous eruption of Kilauea on Hawaii since 1983. Source: Edexcel Unit 4 Option 1 Tectonic Activity and Hazards Contents 67 Event profiles Action for students: 1. Refer to the Exemplar slide for Japan, Tohoku Earthquake and Tsunami (2011) and construct one for Haiti Earthquake (2010). Keep in mind factors of an event profile: magnitude, speed of onset, duration, areal extent, spatial predictability and frequency. 2. Research and construct event profiles as presented on the previous slide for the Haiti (2010) and Tohoku, Japan (2011).

Impacts can be physical, social or economic. Impacts can be: • Direct or indirect, • Short or long-term, • Tangible or intangible, • Negative or positive. Contents 69 Factors affecting an earthquake: Mind map exercise Action for students: 1. Draw a mind map of physical factors affecting an earthquake. 2. Draw another for human factors. 3. Compare your mind map with that of a partner,do you need to make amendments, do they need to make amendments 4. Complete your map for your folder by referring to the following slides. Contents 70 Physical factors affecting the impact of a tectonic event Physical Factors: • Distance from epicentre • Richter Scale / Volcanic Explosivity Index (VEI): the higher on the scale, the more potentially devastating • Duration of the hazard • Scale of the hazard • Frequency of the hazard • Magnitude of the hazard • Time of day • Time of year and climate • Geography of the area, accessibility Contents 71 Human factors affecting the impact of a tectonic event Human factors: • Social, political and economic conditions / level of development. • Population density: rural or urban area • Frequency and severity of hazards affecting the area • Experience from previous hazards in the area • Methods of coping with hazards • Accuracy in predicting the hazards • Effectiveness and response of hazard warning and evacuation procedures • Speed and efficiency of local, national and international emergency response teams and long-term reconstruction and development services • Coordination and perception of the services • Presence of other humanitarian crisis Contents 72 Severity of impacts The hazard and the capacity of people affected to prepare for and resist it determine the extent of the damage. Damage to the environment such as deforestation can make their impact worse. So the severity of impacts depends on both: • Physical factors (attributes of nature) such as the magnitude of the event. • Human factors determining human vulnerability to natural hazards such as population density. Action for students: Discuss whether the impacts on places, people and power of volcanic hazards can be positive and negative, but for earthquakes only negative. Contents 73 Are impacts always negative? Some economists have argued that a natural disasters can be a brutal, but good stimulus for an economy by: • pushing short-term growth; • Helping conflict resolution and community development; • building up-to-date infrastructure and technology in place of outdated ones (in with the new, out with the old); and • focusing international attention and resources on the country.

Label the faults as Dip slip, Strike-slip and Thrust. Mark with arrows to indicate vertical or horizontal movement. . .1000 . . 100 . 10 . . 1 . 5.5 Kilometers 2. Study the graph. Do bigger faults lead to smaller or bigger earthquakes? 6 6.5 7 Magnitude 7.5 8 Source: http://earthquake.usgs.gov/learn/topics/?topicID=53&topic=Prediction 75 Effects of earthquakes on landscapes Action for students: 1. Research faults and draw diagrams of dip slip faults (normal, reverse and thrust), strike slip faults (left or right-lateral) and oblique slip faults. You can refer to http://www.exploratorium.edu/faultline/basics/faults.html Example diagram 3. Be clear about which faults are common at divergent plate margins and which occur at convergent plate margins. 4. Explain how rift valleys form and give an example. Remember: a clear, simple diagram is worth a thousand words. Source: Edexcel Unit 4, Option 1, Tectonic activity and hazards Contents 76 Hazard Trends Why live in tectonically active areas? Prediction PART II – SECTION THREE TECTONIC HAZARDS: HUMAN IMPACTS Contents 77 Section Three Tectonic hazards: human impacts This section is organised around risks, vulnerability and patterns of human impacts – social and economic. • Social impacts refer to trauma and the disruption of everyday life and communities. • Economic impacts can be damage to factories and commercial properties and disrupted transport networks. Together with physical impacts, they determine how places, people and power are affected. Contents 78 Section Three Tectonic hazard: human impacts What impacts do tectonic hazards have on people and how do these impacts vary? Learning outcome By the end of this section, you should: • Understand some of the reasons why people live in tectonically active areas • Know the range of hazards associated with different types of tectonic activity* • Be familiar with the specific impacts of a range of tectonic hazards* • Be aware of trends in the frequency and impacts of tectonic hazards. Contents 79 Hazard Trends PART II – SECTION THREE TECTONIC HAZARDS: HUMAN IMPACTS Contents 80 Geophysical and hydro-meteorological graph activity Action for students: . Look at the two graphs and mark them as appropriate to show: • Rising trend of hurricanes, typhoons, tornadoes and such • Fluctuating trend • Rapidly rising trend of flood events • Increasingly widespread drought affecting millions of people • Rare but devastating • Fluctuating trend usually linked to other hazards Contents 81 Geophysical versus meteorological hazards and trends Geophysical hazard is formed by tectonic/geological processes, for example, earthquakes, volcanoes and tsunamis. The number of geophysical hazards has stayed fairly constant. Hydro-meteorological hazard is formed by hydrological (floods) and atmospheric (storms and droughts) processes. They make up most of the natural hazard events and have increased in number. . EARTHQUAKES Magnitude Class Number M≥8 Great 1 M≥7 Major 15 M≥6 Large 134 M≥5 Moderate 1,319 M≥4 Small ~13,000 Source: WHO/EHA 2002, Disasters & Emergency definitions http://www.who.int/disasters/repo/7656.pdf; USGS Earthquake statistics and Earthquakes and seismicity Contents 82 Natural hazard trends • Whilst better awareness, preparedness and technology has reduced the number of deaths due to natural hazards, the number and frequency of natural hazards and the number of affected people has gone up. • Whilst our capacity to deal with natural hazards and disasters has increased, socio-demographic, economic and technological factors has increased vulnerability further. • The destructiveness of earthquakes has increased, because populations keep rising and more and more people have moved into earthquake risk zones - especially where earthquakes have been infrequent but violent. • Buildings and infrastructure are increasingly expensive and vulnerable, and many people live in housing not been built to withstand earthquakes. • As opposed to other natural disasters, earthquakes occur without warning and even moderate ones tend to affect a widespread area. Contents 83 Disaster hotspots The impact of natural hazards differs between and within countries and regions and countries. Asia is the most affected by natural hazards the Philippines, Japan, India, Bangladesh, China, Indonesia most hazard-prone. Identifying a hot spot can have major implications for development and investment planning, A hazard hotspot is an area of disaster preparedness and multiple hazard zones. In large, rapidly loss prevention. Yet, long lists of growing urban areas in hazard prone areas, the potential for hazards to turn into disasters priorities can be more immediate than risk management. is great. Source: White, Philip, et al, Disaster risk reduction: a development concern, (DFID, 2004) 3. 84 Are Haiti and Japan disaster hotspots? Action for students: Using the disaster websites such as: • Prevention web for risk profile and disaster statistics: http://www.preventionweb.net/english/countries/statistics/risk.php?iso=hti • Centre for Research on the Epidemiology of Disasters, CRED (http://www.cred.be), for frequency, economic and human impact by disaster type and region: http://cred.be/sites/default/files/PressConference2010.pdf 1. List recent natural disasters for Japan and Haiti and discuss each countries capacity to deal with them. Consider location, tectonics, hurricane tracks, typhoons, tsunamis, population, economic development and the natural and built environment. 2. Compare risk rankings for Japan and Haiti. 3. Compare economic and human losses by disaster for Japan and Haiti. Try to explain why 2011 was the costliest year ever for natural disasters with Tohoku, Japan (2011) accounting for 55% of the total US$380 billion economic losses. Contents 85 Why live in tectonically active areas? PART II – SECTION THREE TECTONIC HAZARDS: HUMAN IMPACTS Contents 86 Why do people live in tectonically active areas? Action for students: 1. Reflect on your own the reasons why people live in tectonically active areas, jot down your ideas. 2. Give examples, why do people continue to live in California, Japan or Haiti? 3. Consider: level of economic development, awareness of risks, risks versus benefits, past history of tectonic activity (magnitude, frequency, impact and dates). 4. Discuss with a partner their reasons and yours. 5. Join with another pair, discuss and record all the ideas why people live in tectonically active areas. Contents 87 Why risk living in a hazardous area? There are far more people living in potentially hazardous area than you might expect. Choice e.g. Economic opportunities like tourism, farming, mining, geothermal power Ignorance of the risks and / or underestimation of risk Living in areas of tectonic risk? Inertia; always lived there, roots Nowhere else to go / lack of alternatives Source: Edexcel Unit 4, Option 1 Tectonic Activity and Hazards Contents 88 Many people may not have experienced earthquakes Blue and mauve and yellow dotted lines show Haiti’s last earthquakes 57 and 64 years before the 2010 one. Risk is a probability: without living memory, people may underestimate the risk and consider preparing and planning less a priority. Contents 89 Dregg Disaster Model Dregg’s model (Earthquakes Venn Diagram) shows the overlap of natural hazard and human vulnerability. The greater the scale of a earth process or event and the more vulnerable and exposed the people, the greater the scale of the natural hazards or disaster. “Disasters do not just happen – they result from failures of development which increase vulnerability to hazard events.” e.g., rapid urban growth leading to increased exposure to landslides, earthquakes or fire.” (White, Philip et al 2004, 3) Risk = Vulnerability x Hazard Source: Edexcel Unit 4, Option 1- tectonic activity and hazards. White, Philip, et al, Disaster risk reduction: a development concern, DFID, 2004, 3. Digby et al, Geography for Edexcel, Oxford University Press. Contents 90 World Risk Index Action for students: Looking at the Dregg’s diagram and the world risk index, what places Haiti and Japan at risk? The world risk index launched by the UN Institute in Bonn helps define the interaction between natural hazard and vulnerability. Source: http://ihrrblog.org/2011/09/26/2011-un-world-risk-index/ Contents 91 Disaster Risk Equation People can be affected by natural disasters anywhere. However, the risk of disaster grows as global hazards and people’s vulnerability increases, while their capacity to cope decreases. The Disaster Risk Formula measures hazard vulnerability: Factors that decrease risk include: • Effective warning and preparedness, • Better planning and building practices, • Development and insurance. Source: FAO, http://www.fao.org/docrep/007/ae080e/ae080e01.htm Contents 92 Vulnerability: class-quake Vulnerability: • describes how susceptible a population or parts of a population are to the damage of hazards, notably “the characteristics of a person or group and their situation that influence their capacity to anticipate, cope with, resist and recover from the impact of a natural hazard.”(Wisner, Ben et al 2005, 11) • is determined by processes in the natural environment and by places, people and power. • tends to increase the lower the country’s economic development and sociopolitical stability because risks and vulnerability make the impact of natural hazards patterns worse. Class-quake: The Guatemala earthquake 1976 made headlines as a ‘class-quake’, as it predominately affected the poor, excluded and vulnerable in slums while the urban middle and upper classes remained relatively unaffected. Source: Wisner, Ben, et al, At Risk: Natural hazards, peoples vulnerability and disasters, 2nd ed, (Abingdon: Routledge, 2005) 11. Contents 93 Vulnerability and economic development In less developed countries: • A greater proportion of the population tends to be exposed to risk given population growth, land pressure and urbanisation. Moreover, the poorest tend to be disproportionately affected, often because they have migrated to hazard zones to search for work and may live in sub-standard and cramped conditions that collapse and crush them, the biggest cause of death. • The financial resources, technical capacity, level of education and ability to cope with hazardous events also tend to be lower. • The economies also tend to be driven by growth and tend to be less resilient in dealing with the disruption of the event. • There are also more likely to be other humanitarian crises as well as other issues like weak governance and infrastructure.

Graph by Robert Simmon, based on data courtesy EM-DAT: The OFDA/CRED International Disaster Database (www.em-dat.net) Université Catholique de Louvain—Brussels, Belgium Contents 95 Specific hazard impacts: Human costs The costs of tectonic hazards can be classified broadly as human or economic. Human costs include primary, secondary and tertiary casualties. Over half of disaster deaths occur in LEDCs even though only 11% of people exposed to hazards live there. Primary casualties: People killed or injured by an earthquake or volcano. Casualties tend to be much higher in less developed countries because of: • Limited preparedness, • Less effective warning systems, • Less effective search and rescue services. Secondary casualties: People who survive initially but are injured or die because of insufficient resources and lack of emergency medical care especially in less developed countries Tertiary casualties: People with pre-existing medical conditions aggravated by the hazard event. This includes people who become ill, or die as a result of the post-disaster environment. Contents 96 Specific hazard impacts: Economic costs There are two types of economic costs: • Direct costs: the immediate costs of repairing damage caused by the event. In the case of earthquakes this will often include demolishing buildings fractured by the shock waves and rebuilding from scratch. • Indirect costs: loss of earnings caused by disruption to working life. Increasingly, major natural hazards are causing secondary technological and industrial accidents and emergencies for example, the Fukushima Daiichi nuclear plant in Japan. Contents 97 Exemplar table for your research: hazard impacts over time Action for students: Draw a table to organise and capture your research for each case study using the prompts in the table. Impacts Physical Social Economic Short term Notable examples of natural and humanbuilt landscape destroyed. Fires due to gas pipe explosions and electrical damage? Landslides and flooding? Numbers of killed and injured, noting those in essential service professionals like doctors and policemen injured. Lack of food and health supplies? Damage or loss of homes, transport, communications, health care facilities, energy and water supply systems? Note tangible losses due to the direct impact of property damage like destruction to shops and trade damaged or disrupted. Also, indirect losses resulting from social economic disruption, trade impacted by loss of communication, transport and water and energy supply infrastructure. Looting? Long term Intangible losses like the destruction of important natural and human landmarks and fertile lands. Put here public health problems like disease (e.g., cholera due to contaminated water and lack of hygiene). Numbers of homeless and displaced people needing shelter and rehousing. Information on indirect impacts like stress and psychological damage. Are settlements and shops being rebuilt and, if so, to higher standards? Settlements moved? People rehoused? Is there any positive impact in the form of aid, reconstruction and grants? Contents 98 Haiti research PART II – SECTION THREE TECTONIC HAZARDS: HUMAN IMPACTS Contents 99 Immediately after the Haiti Earthquake (2010) Action for students: Based on the videos and website below extract relevant earthquake facts and record your findings using your table of physical, economic and social impacts.

Action for students: 1. Click on the link and read the news report of Lucy Rodgers of BBC News: http://news.bbc.co.uk/1/hi/world/americas/8510900.stm 2. Use the news report, maps and your own research to write a Report (no more than 1000 words) to account for why the Haiti earthquake had so much greater human cost than the earthquake in Sichuan, China (2008) and in L’Aquila, Italy (2009) which were similar in magnitude. 3. When planning your Report, make sure you review the Report writing schema . Contents 103 Haiti a ‘class quake’? Action for students: 1. 2. Review your research on the Haiti Earthquake and also the Japan Earthquake and tsunami and extract information and data from your research to write an extended report with the following title: The Haiti Earthquake (2010) could be viewed as a ‘class quake’. Compare and contrast the Haiti earthquake with the Tohoku, Japan Earthquake and Tsunami (2011) and reach your own conclusions about whether you believe Haiti was a ‘class quake.’ The websites on the humanitarian response on the previous slides can help illustrate the human impact. Contents 104 Prediction PART II – SECTION THREE TECTONIC EVENTS: HUMAN IMPACTS 105 Earthquake prediction Action for students: 1. Research from the list below possible indicators of imminent earthquake activity and the reliability of these indicators in predicting earthquakes. 2. Divide the research amongst fellow students and share your research with a written note for each student on the reliability of these indicators in predicting earthquakes: Indicators of imminent earthquakes • • • • • • • • • • P and S wave ratio Foreshocks Water levels in wells Radon levels in well Levels of manganese, zinc and copper in basaltic rocks Changes in the electrical properties of rocks Ground deformation Unusual animal behaviour Monitoring how fast strain accumulates Monitoring with satellites electrical charges 3. Is it possible to predict the time, place and magnitude of future earthquakes in a precise, timely and reliable way? Is there a method that is successful beyond chance, statistically more than a lucky guess? Contents 106 Earthquake prediction Action for students: 1. Watch the BBC video on predicting earthquakes on the North Anatolian Fault in Van, Turkey (2011). (04.49 mins). Watch it at least twice and make notes for your research guided by the prompts below http://www.bbc.co.uk/science/earth/natural_disasters/e arthquake#p00gmsgt 2. Consider the prompts: • Why is it easier for scientists to calculate where the next earthquake could have happened on this fault? • What factors did the scientists use for their prediction model? • What was the response of the people to the scientists prediction? • When did the earthquake happen? • What was the magnitude and how long did it last ? • What was the impact of the earthquake-how many people were killed and how destructive was the earthquake on the city. Source: IRIS Contents 107 L’Aquila, Italy (2009) http://www.boston.com/bigpicture/2009/04/the_laquila_earthquake.html Contents 108 Jail for members of the Great Risks Commission Case Study: L'Aquila, Italy (2009) Earthquake of magnitude 6.3 hit the Abruzzi town of L'Aquila on 6 April 2009 following a series of swarms (small, but numerous tremors on a daily basis) during the preceding 2 months. In a public meeting 6 days prior to the main shock, members of Italy's Great Risks Commission downplayed the likelihood of a major quake and did not reiterate what risks people faced if one did occur. This was in response to an amateur seismologist, Giampaolo Giuliani, who was predicting a major quake based on radon readings on his home made radon monitoring devices. On 22 October 2012, 6 scientists and one ex-government official (all members of the great risks commission who attended the meeting) were found guilty of manslaughter by an Italian judge, as they played down the risks of a major shock. They were sentenced to 6 years in prison. Contents Pitfalls to Prediction and Communication of Risks Reasons for authorities and people not to act on disaster warnings: • Uncertainty in scientific information / difficulty in predicting earthquakes • Unease with scientific jargon (communicate in less academic fashion) • • • Lacking emergency response infrastructure ,for example, national and international channels between scientists, authorities, agencies and communities and linked policies. Competing risks/priorities (need to assess likely post-earthquake behaviour to target warnings) Too many false alarms (need to use local hazard indicators, such as, animal behaviour and work with media). Sources: http://www.nature.com/news/2011/110914/pdf/477264a.pdf, http://www.nature.com/news/l-aquila-verdict-row-grows-1.11683, http://blogs.lse.ac.uk/europpblog/2012/11/01/laquila-earthquake-conviction/ http://www.trust.org/alertnet/news/early-warning-of-disasters-facts-and-figures/ Contents Why were the experts jailed? Action for students: 1. Using research from previous slides and taking into account the difficulty of predicting earthquakes, why have these experts been jailed? The media suggests it is because they did not accurately predict the 6 April major shock. Evidence suggests, however, that they misled the public as to the risks of such a quake occurring and that the public then acted as though the risk was small. 2. What are the implications for predicting major natural disasters in the future, not just earthquakes? 111 Strategies for coping Insight into humanitarian work Cholera and GIS in Haiti Social Media Disaster Risk Reduction PART II – SECTION FOUR RESPONSES TO TECTONIC HAZARDS Contents 112 Section Four Responses to tectonic hazards This section focuses on coping with tectonic hazards. Different community capacity can define the approach - the extent to which a country can implement: • Relief • Rehabilitation • Reconstruction, mitigation and preparedness. Contents 113 Section Four Responses to tectonic hazards How do people cope with tectonic hazards and what are the issues for the future? Learning outcomes: • Understand how people and governments cope with tectonic hazards.* • Be familiar with specific ways of adjusting to tectonic hazards.* • Be aware of the different approaches to the challenges of tectonic hazards.* Contents 114 Strategies for coping PART II – SECTION FOUR RESPONSES TO TECTONIC HAZARDS Contents 115 Coping with tectonic hazards Essentially there are three options: • Do nothing • Adjust • Leave The choice of option depends on a number of factors including the nature of the hazard, its frequency, its magnitude, population pressure in the location and the level of economic development. Contents 116 Strategies for coping Strategies used to adjust to hazard threat focus on: • Modifying the loss • Modifying the event • Modifying human vulnerability Capacity for coping derives from being able to access information, authority, institutions, partnerships and plans, resources and procedures to deal with the hazard. Source: WHO/EHA 2002, Disasters & Emergency definitions www.who.int/disasters/repo/7656.pdf Contents 117 The Park Model The model sketches the phases following the tectonic hazard event: The relief phase The immediate response, focus is on saving lives and property. Teams, such as MSF, from outside the immediate area help with search, rescue and care operations. Urgent medical supplies, rescue equipment, clothing and food may be brought in. Rehabilitation phase More complex than relief, this may last for several months, efforts are made to restore physical and community structures, at least temporarily. Reconstruction, mitigation and preparedness Permanent changes are introduced to restore the quality of life and economic stability to the pre-disaster level or better. This can also include mitigation and preparedness – reducing vulnerability.

Photo by Eddy McCall/MSF Contents 126 Haiti 2010: MSF’s response MSF emergency response in Haiti was its largest in its 40-year history. Thousands of Haitians, most of whom were directly affected by the disaster, mobilised along with 3,400 staff to help MSF provide assistance in hospitals and four mobile clinics. MSF’s humanitarian action is based purely on need, independent of any religious or political agenda. Predominately MSF is focused on medical assistance, a subset of humanitarian assistance, but it also performs non-medical activities like providing tents, safe water or latrines. • Further info: September 2012 Humanitarian Snapshot http://reliefweb.int/sites/reliefweb.int/files/resources/map_3010.pdf Contents 127 Emergency medical care in Haiti Wounded people congregate in MSF compound Photos by July Remy / MSF MSF tents provide shelter By the end of June 2010, MSF had distributed more than 28,640 tents, approximately 2,800 rolls of plastic sheeting, and close to 85,000 relief supply kits (made up of items such as cooking utensils, hygiene products and blankets) to people living near the epicentre of the earthquake.

Developments in ICT have enabled a more rapid dissemination of information and have led to the availability of real time situation updates. ICT can support risk communication to the public that clearly and quickly identifies risks to mitigate disasters and promote certain behaviors and measures. The earthquakes in both Japan and Haiti have seen interesting developments which have saved lives and alleviated suffering.

Mobile phones are increasingly used as part of preparation activities and warning communication. Their use in emergency communications, especially through SMS is revolutionising the flow of information. Texts take up less bandwidth than calls and are much less affected by network delays HAITI - “Mission 4636” A group of companies, including Ushahidi, FrontlineSMS, CrowdFlower and Samasource, set up a text message hotline that was supported by the U.S. Department of State and advertised by radio stations. Anyone in Port-au-Prince could send an SMS to a toll-free number, 4636, to request help.

A community of connected volunteers ‘crowdsource’, that is, provide information and/or expertise to enhance relief operations. Crisis mapping draws on crowdsourcing initiatives like Ushahidi and satellite imagery, participatory maps and statistical modelling for early warning and at times of impending crisis. They are not maps by traditional mapmakers that would appear in a standard Atlas! After the 2010 Haiti earthquake, for example, crowdsourcing allowed people on the scene, mapping experts and other stakeholders to communicate what they saw in nearly real time supporting the humanitarian response. There is a lot of potential for relief organisations.

Vulnerability and loss and disruption are minimised through technical, social and economic measures such as pre-positioned plans and community capacity building for improving development.

This can be done by minimizing the effects of disaster through building codes and zoning, public education and vulnerability analyses. • In primary mitigation the presence of the hazard, where possible, and of the vulnerability is reduced. • Secondary mitigation is intended to decrease the impact of the hazard through preparedness and planning.

Contents 160 Preparedness Secondary mitigation Secondary mitigation seeks to reduce the effects of the hazard through preparing and planning how to respond. Measures “ensure the organized mobilization of personnel, funds, equipment and supplies within a safe environment for effective relief.”(WHO/EHA 2002) • For preparedness, these efforts include preparedness plans, emergency exercises and training; warning systems. • In terms of response, measures such as search and rescue and emergency relief intend to minimize the hazards created by a disaster through search and rescue, emergency relief. Source: WHO/EHA 2002, Disasters & Emergency definitions; http://www.who.int/disasters/repo/7656.pdf Contents 161 Planning for earthquakes • Planning for an earthquake is usually based on the assumption everything will be destroyed, for example, an earthquake of magnitude 8.0 or above in San Francisco would destroy everything. • Earthquakes happen without warning and it is impossible to plan response activity in advance. • Earthquakes are more likely (by a ratio of 3:1) during non working hours) • Communication systems may well be damaged which will hamper response management. • Aftershocks will cause additional damage, interfere with response efforts and cause anxiety in the population.

Satellite communication has improved which has reduced the lag between data collection and warning. A recorder on the seabed that transmits data about anomalies to a buoy on the surface.

Early warning needs to be followed by action to make any difference. Even a lead time of a few seconds can allow some mitigating measures like shutting down gas supply lines. Government agencies must have emergency infrastructure, for example, working channels of communication in place in order to communicate warnings to local communities. (see Japan and Preparedness) Early warning systems such as TriNet and ShakeMaps and damage assessment / prediction tools such as GPS, GIS mapping systems predict and illustrate probable damages from a number of disaster scenarios.

There tend to be lower awareness of risks, less public education and fewer drills, but even where people are aware, economic survival takes precedence over safety concerns. • Public capacity to deal with search and rescue and mass casualties can be lower.

Contents 171 Logistician’s blog from Haiti International humanitarian system and assistance APPENDIX Contents 172 Haiti Blog: Before the earthquake (1) Logistician, Port-au-Prince, Haiti • Life progresses as usual here, but this is not a usual situation compared with my experiences back home. A pregnant woman arrived in the hospital yesterday and it was all hands on deck. We already had a full maternity ward, with patients on makeshift beds in the corridors. But what do you do when yet another one arrives who needs emergency care? I arrange for another bed packed beside the others and let the medics get on with their work. One emergency Caesarean Section later and mother and child are well. • It's not just the emergencies that are exciting. All aspects of my work here are interesting. MSF is running a maternity hospital in the capital. There are no other facilities like it in Haiti at all and the statistics on mother and child health are still terrible. Maternal and infant mortality are especially high which is why MSF's emergency care for complicated deliveries is so important. • My job is so varied. The infrastructure in Haiti is very poor, with basic services such as electricity, clean, running water and transport very unreliable. I make sure that the hospital has all of these, backing up electricity with our generators, servicing the water systems and running the fleet of cars MSF uses for transporting staff and patients alike. I also run the medical supply system which is a huge challenge, trying to get safe, certified medicines to the patients through our supply hub in Amsterdam. The cold chain is a particular challenge in this heat – many medicines must be kept between 2 and 8 C at all times and with unreliable electricity we use a system of fridges and cold boxes. • The country is so poor which means MSF has to bring in virtually all its supplies. You cannot rely on anything being available which means planning months ahead. I have found this to be pretty tricky when you can't really predict how many patients you will have from one week to another! 173 Before the earthquake (2) • And now a little about the country itself from what I have seen. Port-Au-Prince is a thriving, but very busy city with everything you might expect of a capital city in the developing world. There are markets everywhere and a huge contrast between rich and poor. The slums are very basic and house an amazing number of people, but this is also where the gangs are based. They control so much of the city and we struggle to get anything done when they are involved. People seem to get by though, working, trading and buying in the markets, fishing etc., although most live without basic services in the shanties and neighbourhoods. • In the countryside it is a little different – Haiti is very densely populated and most of the forest has been cut down to provide building materials and wood for making charcoal to cook with. One of the most amazing sights is the border with Dominican Republic where you can physically see the line of trees that signifies the Dominican side. The country is hilly and exposed to all manner of natural disaster – in the last 10 years they have seen hurricanes, deforestation, flooding and earthquakes, all of which make it a very precarious place to live. • All in all, we manage to make things work OK here. MSF manages to provide emergency care to mothers and children in a place where it would otherwise not exist. It is hard work, but we still manage to have some fun and just sharing all of this with our national staff and being part of our patients' lives is very rewarding. I saw the mother and baby who I made the makeshift bed for this morning and they are both well. It makes all the hard work worthwhile. Contents 174 Immediately after the earthquake (1) • I simply don't have time to write, and I don't know where to start, but I must update you briefly about what has happened. Also to say that I am OK, but so many are not. Two days ago the earth shook and changed the face of this already struggling country. It is not an overestimation to say that virtually everything has been destroyed. • We do not have much information about what has really happened because all the communication except satellite phones are down. I can send this email via the sat link, but we only download once a day. The reports we have had are only from our staff, many of whom are still missing. Some of my international colleagues were missing for a time, but are now all accounted for. We know that most homes have collapsed, the hospital is almost totally destroyed and many of our patients and staff are under the rubble. We hear that rescue operations will begin tomorrow, but little is known. There is total chaos here. • We have been without water and electricity since the earthquake, but I have managed to get some basics sorted out. We are still using our emergency water supplies and I simply don't know when they will be replenished. I have rigged up some basic electricity using our small back up generators, but we only have a limited amount of fuel for them. Contents 175 Immediately after the earthquake (2) • Everyone is in shock: roads are blocked, essential services are destroyed and we now have to make sense of the situation and work out how we can help in the best way possible. There are so many things to do. We must work out how to treat the wounded, how to get clean water (not just for ourselves, but also the entire population in the city), how to get supplies in as the port and airport are both closed. And what about our existing patients in the maternity hospital? Babies will no doubt still be born and who will look after the complicated deliveries? To be honest, we are completely overwhelmed here, but we must work out at least where to start. • I have just heard a report that there maybe thousands of people buried under the rubble. That means that sadly many will be dead and many more injured. Right now we are not set up to provide medical or humanitarian care to these people so I must focus on rebuilding our facilities and getting more emergency supplies into the country. • I have very little idea how the Haitian people are coping with the tragedy and the mess. Some of our staff have made it in today and have told us about how their shanties have been flattened, but people are busy rebuilding them already. The trouble is that with rubble everywhere and no supplies coming into the country, nothing can get to the neighbourhoods. Food is already short and water can only be obtained from old wrecked piping. People are still pulling friends and neighbours out of the rubble. No news has come in yet about the situation in the countryside, but we do know that the epicentre of the quake was right in Port-au-Prince. We have to hope that some of the outlying areas were spared, but I just don't know. • There is so much to be done and I have to work with colleagues to prioritise the most essential things first. Which means I have to go....! Contents 176 Six months after (1) • Haiti is still such a mess. The immediate emergency of the earthquake has passed, but there is still so much to do. Essential services remain in very poor repair and the challenges I faced pre-earthquake are still there. They just feel multiplied a hundred times because now we have a whole catalogue of new problems. • As you all know, the death toll was horrific, but the mess that remains challenges us to the limit. The emergency wounded have been tended to, but we still have awful orthopaedic cases that we see and there will continue to be lots of rehabilitation necessary. Basic services have broken down and supplies have been so limited we have also become aware of a problem with people living with HIV/AIDS as their essential medication is very short supply. • The maternity hospital is, mercifully, up and running to the best of our abilities. I have worked round the clock to help a huge team construct a new hospital out of container like units and we have managed to get the essential medical equipment and supplies from Amsterdam. In some ways things have stabilised and I now feel that we have a bit of time to reflect on the last few months. It has been very traumatic, not least of which has been coming to terms with the death of some of our staff and their families. Contents 177 Six months after (2) • If cholera comes to Haiti it could be horrific. The population is still in shock from the earthquake and the destruction it caused, but this would be too much for them. MSF has lots of experience around the world at dealing with cholera, but in this place it would be so hard to deal with, given the lack of infrastructure. • The other problem is security. The earthquake created a situation where people had to fend for themselves and we have seen a return to the gang culture that plagued the country preearthquake. The gangs control everything and even we, as MSF, have to negotiate this situation. The gangs do not think twice about using violence if they do not get their own way and this has complicated our work immeasurably. There are times when it simply is not safe enough to go out and do your job. Just yesterday I had planned to go and check the water supply for one of our community clinics, but we received word from the local gang that they controlled the water supply and threatened me if I went to check it. How do we know they are doing it well? What are they charging people who have nothing for clean water? What are the health implications if people are forced to use water from the stream? I have no answers to these questions, but I still have the responsibility of ensuring that people have clean water. • Now that things have settled down a bit life has slowly resumed in Port-au-Prince. The markets are running again and I see people picking through the rubble to get about. Some of the roads have been cleared so people can move about more freely and the air and seaports are running as before the quake. Many of the shanty buildings have been put together again, but the bigger houses are still as they were, in ruins. Contents 178 Six months after (3) • Some construction has begun again, but not a lot. The good news is that produce can get into the city from the countryside so food is a little more available, but as it is so expensive, many people cannot afford the basics. So many people are still living in tents, given by the aid agencies, and surviving on handout food, water and cooking facilities. There is not a patch of green in the city any more, as all the parks, even the golf course, have been used as camps for people who lost everything. • Before I go, I just want to tell you about one amazing thing that has come out of the disaster, which we have used quite a lot to help us work. It seems that a bunch of computer users from around the world have been analysing satellite mapping data from various sources, and mapping the movements of people. For example, they can tell us where isolated groups of tents have been set up so that the aid community can reach them. They can also tell us when people are taking long diversions to reach certain destinations due to road blockages, which helps to clear the important routes. It's been amazing to know that people from their own homes, all over the world, have been helping with the mapping efforts that have been so useful to us on the ground. • I have to say I am looking forward to the end of my assignment next month as I am now completely exhausted. It is just so hard to work so many hours for so long, but what alternative is there when the needs around you are so great. I have learned so much in my time here, but there is so much still to do. How will this place ever recover?

About 15.2 million worldwide according to UN Refugee Agency. ** IDP: an internally displaced person seeks refuge from violence or disaster within the borders of the own country. IDPs outnumber refugees by more than two to one, but no single UN or other international agency has responsibility for responding to internal displacement. About 26.4 million worldwide according to Internal Displacement Monitoring Centre.

International humanitarian Law designed to minimise the negative impact of war (while paradoxically accepting it) • Geneva Convention, other treaties, customary law that deals with methods or means of warfare and the protection of civilian populations • Speaking out (témoignage) against violations of humanitarian law forms part of MSF’s mission. Not the same as ≠ Principles of humanitarian action ≠ Human Rights Law, which is embodied in the Universal Declaration of Human Rights applies to all people at all times, whether or not there is war, or whether or not they are civilians. Contents 184 Humanitarian Principles: Principles of humanitarian action Humanitarian principles illustrated by Médecins Sans Frontières • Humanity: MSF is “committed to bringing quality medical care to people in crisis regardless of their race, religion, or political affiliation.” • Impartiality: its “work is based on the humanitarian principles of medical ethics and impartiality.” • Independence: “MSF operates independently of any political, military, or religious agendas. Medical teams conduct evaluations on the ground to determine a population's medical needs before opening programs, aiming to fill gaps that exist (rather than replicating services that are already offered) or reach communities that are not being assisted. The key to MSF’s ability to act independently in response to a crisis is its independent funding. Ninety percent of MSF's overall funding (and 100 percent of MSF-USA's funding) comes from private, non-governmental sources. In 2009, MSF had 3.8 million individual donors and private funders worldwide.” • Neutrality: “As an organization, MSF is neutral. It does not take sides in armed conflicts, provides care on the basis of need alone, and pushes for increased independent access to victims of conflict as required under international humanitarian law.” Source: Doctors Without Borders, http://www.doctorswithoutborders.org/aboutus/ Contents 185 Humanitarian assistance • Complex relationship between humanitarian assistance and political action • Constantly need to define and question the purpose of humanitarian action, its operational principles and relationship with other actors like military, governments and aid agencies. • Contextual differences, time pressure and fast-changing situations on the ground are challenging. • The multiplicity of agencies and actors, often independent, can make coordinated and effective action harder. • Emergencies can polarise objectives and it can be difficult to be objective. • Further issues can arise because of refugees and internally displaced people and public health emergencies. Contents 186 Priorities of natural disaster response Areas that are recognized as priorities in humanitarian interventions and that evaluations often flag as shortcomings in operations: • Linking relief, recovery and development; • Mapping and monitoring needs and target groups; • Synergy between local, national and international capacities; • Coordination of humanitarian actors and projects; • Disaster Preparedness and vulnerability reduction. Evaluation is “systematic and impartial examination of humanitarian action intended to draw lessons to improve policy and practice and enhance accountability.” Source: Assessing the Quality of Humanitarian Evaluations, The Alnap Quality Proforma, http://www.alnap.org/pool/files/QualityProforma05.pdf Humanitarian response To Natural Disasters: A Synthesis of Evaluation Findings, http://www.norad.no/en/tools-and-publications/.../107610?_...true... Contents 187 Further info on Haiti APPENDIX Contents 188 Haiti before 2010 Haiti pre-earthquake: • First independent republic in Caribbean, it rebels against slavery and overthrows colonial rule in 1804, but remains affected by it. • After 1804, history of two-caste society continues with mixed-race descendants taking place of French elites. Mulattos dominate the black population and Haiti’s politics and economy. • Dictatorships and coup d’etats, violence and instability entrench a notoriously inefficient and corrupt government and economy as well as a culture of social unrest. • Armed rebellion forces President Jean-Bertrand Aristide out of office in 2004. In 2006 democratically elected president and parliament finally elected. • Add to this environmental degradation and the potential of the mountainous tropical island as a tourist destination is ruined.

They provide most of the services like healthcare and education and development efforts, expertise and funding not provided by the government. They can be perceived as more stable and accountable than the Haitian government. • Most like government are concentrated in Port-au-Prince and urban areas, meaning that there is little support from NGOs and government for sustainable livelihoods in rural communities. • Most NGOs are in relief during acute emergencies (like MSF) or reconstruction and development (like Oxfam). To use a metaphor, the former tends to give out fish to keep people alive, while the latter later teaches to them fish. • The scope of the problems is beyond the mandate and capacity international assistance. International assistance can include other nations, armies, international agencies, non-governmental organisations, foreign philanthropists and volunteers. Developed and wealthy nations are less likely to require or request foreign aid in the wake of a disaster than less developed ones.

Government is stalling on land reform, tenure and ownership legislation; there is lack of clarity about ownership of land and Haitian elites are not cooperating as landowners. • Translating an urban development strategy into practice. • People are unwilling to leave Port-au-Prince because of inability to make a living outside of the capital in spite of incentivized government rural relocation programs.

Through Open source mapping like www.openstreetmap.org, a Wikipedia-like site, amateur map makers could update maps faster following the earthquake than the US Department of Defense. Armchair disaster relief agents around the world edited maps and information about Haiti to assist aid workers. Action for students: 1. 2. Watch the “What is Ushahidi” video http://www.ushahidi.com/ . Discuss: the future – an opensource system that does not rely on an existing interface and can truly develop in an impromptu way when emergency needs occur?
