Tips to survive an earthquake

During the Earthquake:

  • If you are indoors, stay there. Quickly move to a safe location in the room such as under a strong desk, a strong table, or along an interior wall. The goal is to protect yourself from falling objects and be located near the structural strong points of the room. Avoid taking cover near windows, large mirrors, hanging objects, heavy furniture, heavy appliances or fireplaces.
  • If you are cooking, turn off the stove and take cover.
  • If you are outdoors, move to an open area where falling objects are unlikely to strike you. Move away from buildings, powerlines and trees.
  • If you are driving, slow down smoothly and stop on the side of the road. Avoid stopping on or under bridges and overpasses, or under power lines, trees and large signs. Stay in your car.   

After the Earthquake:

  • Check for injuries, attend to injuries if needed, help ensure the safety of people around you.
  • Check for damage. If your building is badly damaged you should leave it until it has been inspected by a safety professional.
  • If you smell or hear a gas leak, get everyone outside and open windows and doors. If you can do it safely, turn off the gas at the meter. Report the leak to the gas company and fire department. Do not use any electrical appliances because a tiny spark could ignite the gas.
  • If the power is out, unplug major appliances to prevent possible damage when the power is turned back on. If you see sparks, frayed wires, or smell hot insulation turn off electricity at the main fuse box or breaker. If you will have to step in water to turn off the electricity you should call a professional to turn it off for you.

Elastic rebound


The elastic rebound theory is an explanation for how energy is spread during earthquakes. As plates on opposite sides of a fault are subjected to force and shift, they accumulate energy and slowly deform until their internal strength is exceeded.

Volcanoes

A volcano is an opening, or rupture, in a planet's surface or crust, which allows hotmagmavolcanic ash and gases to escape from below the surface
