Earthquakes are the sudden, rapid release of energy stored in rocks.
The constant motion of the earth’s surface causes an earthquake. The earth’s rock layer is broken into large pieces. These pieces are in slow but constant motion. They may slide by each other smoothly and almost imperceptibly.
From time to time, the pieces may lock together and energy that accumulates between the pieces may be suddenly released. The energy that is released travels through the Earth in the form of waves. People on the surface of the earth then experience an earthquake.
Experiencing an Earthquake? Check out these survival tips:
- Drop down; take cover under a desk or table and hold on.
- Stay indoors until the shaking stops and you’re sure it’s safe to exit.
- Stay away from bookcases or furniture that can fall on you.
- Stay away from windows. In a high-rise building, expect the fire alarms and sprinklers to go off during a quake.
- If you are in bed, hold on and stay there, protecting your head with a pillow.
- If you are outdoors, find a clear spot away from buildings, trees, and power lines. Drop to the ground.
- If you are in a car, slow down and drive to a clear place. Stay in the car until the shaking stops.
