At the Earth's surface, earthquakes may manifest themselves by a shaking or displacement
of the ground.Sometimes, they cause tsunamis, which may lead to loss of life and
destruction of property. An earthquake is caused by tectonic plates getting stuck and putting
a strain on the ground.The strain becomes so great that rocks give way by breaking and
sliding along fault planes.Earthquakes may occur naturally or as a result of human
activities.Smaller earthquakes can also be caused by volcanic activity, landslides, mine
blasts, and nuclear experiments.In its most generic sense, the word earthquake is used to
describe any seismic event—whether a natural phenomenon or an event caused by
humans—that generates seismic waves.Most naturally occurring earthquakes are related to
the tectonic nature of the Earth.Such earthquakes are called tectonic earthquakes.
-What damages can earthquakes do ?
Ground shaking from earthquakes can cause buildings and bridges to collapse; disrupt gas,
electricity, and telephone services; and sometimes trigger landslides, avalanches, flash
floods, fires, and tsunami.

-encyclopedic definition:
An earthquake is a sudden shifting of masses of rock beneath Earth's surface. This motion
releases enormous amounts of energy and sends out shock waves that cause the ground to
shake. Geologists believe that no spot in the world is completely safe from earthquakes. The
great internal forces of the planet are constantly changing the shape of Earth's surface. In
fact, Earth has been resounding with earthquakes for more than four billion years.
Thousands of earthquakes occur each day. While not all of these earthquakes are
significant, some are powerful enough to wreck cities and kill thousands of people. In the
twentieth century alone, deadly earthquakes have claimed more than a million lives.
-the most known examples :
22 May 1960 – Chile Magnitude 9.5
The world's most powerful earthquake left 4,485 people dead and injured and 2 million
homeless after it struck southern Chile in 1960. The port of Puerto Saavedra was destroyed
in the ensuing tsunami, which caused $550m worth of damage in Chile and killed a further
170 people as five-metre waves hit the coasts of Japan and the Philippines. A day later
Volcán Puyehue in Chile's lake district spewed ash 6,000m into the air in an eruption that
lasted for several weeks.
28 March 1964 – Prince William Sound, AlaskaMagnitude 9.2
26 December 2004 – Off the west coast of northern Sumatra
Magnitude 9.1
Indian Ocean Earthquake of 2004
March 11, 2011, Japan had the strongest earthquake in the history. The earthquake
struck below the North Pacific Ocean, 130 kilometers or 81 miles east of Sendai, the largest
city in the Tohoku region.
The Tohoku earthquake made a tsunami. “Harbor wave” is a series of powerful waves
caused by the displacement of a large body of water. Most tsunamis, like the one that
formed off Tohoku, are triggered by underwater tectonic activity, such as earthquakes and
volcanic eruptions. The Tohoku tsunami produced waves up to 40 meters or 132 feet high,
More than 450,000 people became homeless as a result of the tsunami. More than 15,500
people died.
The tsunami also severely crippled the infrastructure of the country. In addition to the
thousands of destroyed homes, businesses, roads, and railways, the tsunami caused the
meltdown of three nuclear reactors at the Fukushima Daiichi Nuclear Power Plant. The
Fukushima nuclear disaster released toxic, radioactive materials into the environment and
forced thousands of people to evacuate their homes and businesses.
2. Disaster management plan ( no.4 )
2.1 Mitigation measures we have now - includes documents, codes, plans and zoning
policies in the potentially affected area
2.2 Prevention measures we have now - measures for warning, trainings special
services and citizens have, educational materials provided for the people, the
stockpiles of resources (food, water, medical supplies, other materials) which will be
used in a case of disaster
Mitigation plans
Bullet train
Japan is known as a train dominated country and their network of shinkansen (bullet trains)
are the transport of the future, whizzing across the countryside at an eye-watering pace. To
ensure the safety of all passengers, the trains are equipped with earthquake sensors that
are triggered to freeze every moving train in the country if necessary. In 2011, when a 9.0
magnitude quake hit Japan, there were 27 moving shinkansen in action. Every single train
was triggered by smaller pre-quakes and stopped before the major quake hit, resulting in
zero deaths or even injuries.
Immediate TV coverage
If an earthquake hits the nation, all of Japan’s TV channels immediately switch to official
earthquake coverage, ensuring that that population is well informed on how to stay safe. The
coverage delivers info on the quakes, where to seek protection, and whether any tsunamis
are approaching, giving citizens time to retreat to higher ground.
Water Discharge Tunnel
One of the most impressive feats of engineering is Tokyo’s little-known Water Discharge
Tunnel located on the outskirts of the city, sitting patiently underneath a soccer field and
skate park. This large hidden tunnel collects flood waters caused by natural disasters like
cyclones and tsunamis and safely redistributes the water into the Edo River. This means if
the area is hit with an earthquake and triggers a tsunami, the city should be spared any
major flooding. It took 13 years to build and cost US$3 billion, but you can’t put a price on
how many lives it promises to save.
Prevention
Awareness and education on disaster prevention
Just as other schools around the world may hold emergency fire drills, schools in Japan run
regular earthquake drills, some as often as once a month. From a young age, schoolchildren
are educated on the best way to seek protection and stay safe if an earthquake hits their
area. The most common method during the drills is for children to get under their desks and
hold onto their table legs until the quake is finished. If playing outside, children are taught to
go straight to the centre of an open space to avoid getting hit by falling debris.
Earthquake Memorial Museum
Another way Japan helps protect its population against future natural disasters is by learning
from past events. In 1995, the city of kobe was struck by the completely devastating Great
Hanshin Awaji Earthquake, which killed 5,000 people and destroyed tens of thousands of
homes. Following the rebuilding of the city, Kobe also constructed the Kobe Earthquake
Memorial Museum , Built to remember the people lost during the disaster, it also runs as an
education centre filled with useful displays and educational facilities on disaster prevention
and survival.
Earthquake survival kits
How each household prepares for an earthquake varies; however, many homes are stocked
with earthquake survival kits. Stocked with first aid equipment, bottled water, food rations,
gloves, face masks, insulation sheets, survival tools like torches, and even radios that
broadcast regular updates. You can pick up all the necessary supplies for survival kits from
most drugstores or lifestyle stores
Earthquake detectors
Technical innovations progress daily to ensure the earthquake-readiness of the Shinkansen,
the high-speed rail that links cities throughout Japan. The East Japan Railway Company (JR
East) introduced the Earthquake Early Warning System for the Shinkansen in 1998, which
detects preliminary tremors from seismographs located along the tracks, the seafloor, and
inland, and then brings trains to an emergency stop by interrupting the electric supply. This
prevents major accidents during an earthquake. Weather radar also help have cutting edge
accuracy to detect
The high rises of Tokyo, Osaka and Yokohama dominate the cityscapes around them. The
towers give the impression of being as immovable and steadfast as a human-made structure
can be.
These towers are the fixed backdrop to daily urban life in Japan, as they are in any large and
developed city in the world. While people and traffic bustle around them, they are fixed and
still – the pins that hold the rest of the hectic city together.
It takes an earthquake to reveal that perspective to be an illusion. In Japan, skyscrapers
have to be able to move.
Japanese high-rise construction commonly uses a grid of steel beams and columns that
evenly distributes seismic forces across the structure and diagonal dampers that serve as
shock absorbers. American high-rises are typically built with a concrete core that resists
most of the seismic forces of an earthquake
3. Disaster management in a case of disaster. (No. 9,12)

This required to include the information about the measures provided to restore normal life in
the area.
Compensation for victims
From the 2011 Tohoku earthquake and tsunami, a total of 520 billion yen has been
donated to disaster-hit areas, and 930,000 people have been aided in their efforts to recover
from the disaster.
Earthquake Observation Equipment
Develop systems for constant monitoring/information service of earthquake and Tsunami
Seafloor Observation System for Earthquakes and Tsunamis of Submarine Cable Type
makes it possible to observe submarine earthquake activity and associated tsunami activity.
Excellent evacuation effect is expected by combining it with an alarm system.
GPS Buoy System
GPS‐mounted buoys can measure offshore waves and tidal levels, including tsunamis, in
real‐time by using satellite positioning information.
Real-time Analysis System of GNSS CORS (REGARD System)
The positons of GNSS Continuous Operating Reference Stations (CORS) are precisely
calculated and monitored. The system estimates ground movements due to earthquakes,
volcanic activities, and plate motions, and contributes to hazard mitigation.

can immediately and accurately observe hazard phenomenon of earthquakes, tsunamis and
volcanic eruptions in Japan. The observed data is utilized not only for research on natural
disaster mechanisms but also for disaster reduction as it is directly provided to central
government, local governments and private companies.
・Satellite observation data for emergency responses
Earthquake-Resistance Wharves
( Jacket method )
= Jacket pier is constructed by using the jacket type structure which is a space truss of steel
pipes fixed to the seabed by steel pipe piles. It has high horizontal rigidity and high
earthquake‐resistance.
- As a result of damage on bridges in the Great Hanshin‐Awaji Earthquake, measures
have been promoted in Japan.
- The image of Jacket Method
-Reinforcement of bridges
Based on many experiences of disasters in the past, Japan has promoted
Seismic Strengthening / Isolation-system of Houses/Buildings
ex. Seismic isolator
-There was no fall/collapse caused by earthquake vibration on seismic reinforced bridges in
the Great East Japan Earthquake. Therefore, utilization of such technology is expected in
overseas including know‐how of architectural design.
Strip for fastening steel plate
Reinforcement of columns
Seismic isolator Steel
Filling with mortar
Carbon fiber sheet
Reinforcement by covering with steel plates
Reinforcement by wrapping with continuous carbon fiber sheet
In the Great East Japan Earthquake, seismically isolated buildings didn’t have
damages to the structural frame caused by earthquake motion, and proved the
effectiveness to the major earthquake.
Training Programs ”Knowledge Co-creation Programs”
Japan invites trainees from developing countries to many programs in such fields as DRR
governance and mainstreaming, earthquake, tsunami, flood, hydromet and so on. These
programs are conducted with knowledge and experiences on DRR in Japan.

・Support for livelihood Recovery Considering Victims
- implemented with victim’s consent
4. Conclusion. Summarize the information from your video and provide your opinion
about the adequacy of the measures for this kind of event. (No. 2,13)
earthquakes occured from shaking or displacement of the ground which cause tsunamis, as
it could lead to death and property damages. Earthquakes could occur from both natural and
man made. Natural occurrences such as volcanic eruptions and landslides, man made
activities such as nuclear experiments in the ocean and mine blasts could also lead to
earthquakes as well, as a result of that it generates waves, as the waves travel from
underwater to the surface it caused tsunamis to happen.
-What damages can earthquakes do ?
Ground shaking from earthquakes can cause buildings and bridges to collapse; disrupt gas,
electricity, and telephone services; and sometimes trigger landslides, avalanches, flash
floods, fires, and tsunami
