Large earthquakes lead to massive disasters, destroying buildings and utility lifelines, causing landslides, fires, tsunamis, ground cracks, soil liquefaction and so on. They also bring about tremendous damage to human life and property.
Earthquakes are generated by the shifting of faults and plates. The mechanism of the generation is as follows:
- When an oceanic plate and a continental plate collide, the continental plate pushes into and subducts under the oceanic plate.
- The subduction of the continental plate under the oceanic plate progresses gradually as time passes, and the strain accumulates.
- When the accumulated strain reaches its limit, the continental plate suddenly lifts up to return to its original state, generating the earthquake.
At evacuation facilities
- Do not walk through narrow paths between buildings and keep away from objects such as block fences that can fall down.
- When there are people who are sick or injured and need emergency care in the evacuation facilities where it is difficult to care them, contact the city office through the person in charge to get instructions.
- Obtain information through the radio or from the person in charge, and do not believe rumors.
- Stay at the evacuation facilities until the evacuation advisory or the evacuation order is cancelled.
Protect your head
- It is particularly important to protect your head.
Get under solid structures such as a strong table, while keeping your head away from the tabletop and firmly taking hold of its legs, to protect yourself from falling objects.
- Protect your head with a cushion or similar object. If there is nothing around for you to use, protect your head with your hands. Please remember to keep away from objects such as tall furniture and refrigerators that may topple over.
- Narrow spaces such as a restroom or bathroom that contain numerous pillars are comparatively safe.
