II. Background Information
Natural events do not automatically become hazards, much less cause disasters. A natural event can
be likened to a weak concrete fence that may collapse even with just a slight push. It does not pose a threat to
anything or anybody if there is nothing or no one nearby. Once you park a car or stand right beside it, it
becomes a hazard.
According to RA 10121 also known as Philippine Disaster Risk Reduction and Management Act,
hazard is a dangerous natural phenomenon, substance, human activity or condition that may cause loss of life,
injury or other impacts, property damage, loss of livelihoods and services, social and economic disruptions or
environmental damage. Infrastructures, public or private facilities, households, transportation, and humans are
the elements exposed to these hazards.
What is hazard mapping?
Hazard mapping is the process of identifying the spatial variation of hazard events or physical conditions
(e.g., potential ground shaking, steep slopes, flood plains, and hazardous materials sites). Through this process,
one side of the hazard-exposure-vulnerability risk triangle may be displayed in hazard maps. Hazard maps are
indispensable for information and education campaigns to hazards scientists, and to land use planners. Hazard
maps are quite useful in communicating vital information about the spatial variation of size and potential
intensity of a particular hazards.
Steps in Hazard Assessment:
1. Identification of type of hazard: To identify the types of hazards. Depending on the typed of
hazards identified, the process may need to be continued on separate basis for each type of hazard or
group of hazard types.
2. Frequency: To find the seasonality of occurrence of hazards like how frequent and which seasons
which kind of hazards are expected.
3. Risk and coverage: To determine of the probabilities of occurrence on an ordinal scale(highmedium-low).
4. Magnitude: To estimate or calculate the scale (strength, magnitude) of hazardous events.
5. Causes of hazards: To Identifying the factors influencing the hazards like climate change.
6. Likelihood of new hazards: To identify due to natural factors, economic, social and political trends,
industrial hazard, and new forms of epidemics and diseases (e.g. bird flu).
Geological hazard map is a map indicating the areas that are vulnerable to hazards caused by earthquakes,
volcanic eruptions and landslide.
The hazard map tools give the information that in the specific map, legend and credible sources 10
province are determined as most prone to earthquake. They are composed of Surigao Del Norte, Davao
Oriental,
La Union, Pangasinan due to Manila fault, Benguet, Pampanga, Tarlac, Ifugao, Nueva Vizcaya, Nueva Ecija
due to active fault line, zone, and trench. In volcanic eruptions alertness is classified via activeness of the
volcano. However, in the case of landslide, it shows that northern Luzon has the highest-danger zone due to
its location.

Landslide
Due to the increase of industrialization processes of the community, human activities triggered and
aggravated a natural process such as heavy rain full and earthquakes causing Landslide.
Human Activities that Triggers and Aggravate Landslide
● Clearcutting is one method done by logging companies to cut down every marketable tree from a
selected area to harvest timber.
● Deforestation or removal of trees that hold water and top soil.
● Kaingin /slash and burn is a method that cuts down and burns off existing vegetation.
● Mining and quarrying operations use explosive in their blasting techniques to break rocks and
gather ore deposits.
● Construction activities such as building of roads and railways may interfere or change the natural
drainage of water especially during heavy rain.
Tropical Cyclones, Monsoons, Floods, or Ipo-ipo
Tropical cyclones are one of the biggest threats to life and property even in the formative stages of
their development. They include a number of different hazards that can individually cause significant impacts
on life and property such as storm surge, flooding, extreme winds, tornadoes and lighting. Monsoons are a
seasonal change in the direction of the prevailing or strongest wind of region. They can cause wet and dry
seasons throughout the tropics. Flood means an overflowing of water onto land that is normally dry. Ipo-ipo
/tornado is a rotating column of air extending from base of a thunderstorm down the ground. It has the
capability to destroy well-made structure, uproots trees and hurling objects.
Coastal Processes
Coastal processes are driven by winds, waves and currents that begin to sculpt the edges of the
coastline. Rocks and cliffs are cut back, bays are carved out of soft rocks, harbor entrances are straightened
with bars and spits and pieces of the coast are joined together with sand gravel. Other process which influence
the coastal environment include longshore drift, winds and erosion. In unavoidable occurrences driven by
nature and amplified by human action, they cause damage to the shorelines through coastal erosion (process
by which local sea level rise and strong wave action), submersion (when the sediment is submerged under
water and eventually replaced back to its original position) and salt intrusion (when the saline water is drawn
into a fresh water aquifer). Breakwaters are offshore structure that protect coasts from parallel waves and in
turn, prevent erosion and submersion. An increase in development and population may lead to increased
amounts of waste disposed off in a coastal area. Sometimes, the waste disposed of landfills built near the
coasts. Thus, construction of these landfills not only causes land and water pollution to the coastal area but
also amplifies the effects of coastal erosion and result in salt intrusion.
Mitigation in the impact of land development, waste disposal, and construction of structure on control
coastal processes.
Effective solid management planning and implementation must be carried out by the residents and
users of coastal areas. Managing solid wastes at the community level prevents coastal deterioration. Industrial
wastes must also be properly managed and not released in coastal areas. In a coastland development risk
assessment, blueprint development and control activities can prevent the effects.
