Causes of Earthquake

Earthquakes happen deep underground along tectonic plate boundaries. Tectonic plates are what make up the earth's crust, its outermost layer. They are always moving because the part of the earth underneath them is like a fluid. However, each plate is lined up pretty well with the other plates around it. So as they move, they create tension and pressure as they slide past and bump into each other. These forces are felt on the surface of the earth as an earthquake.


Safety from Earthquake

To protect yourself from earthquakes:
1. Drop down and take cover under a desk or table and hold on.
2. Stay indoors until the shaking stops and you are sure it's safe to exit.
3. Stay away from bookcases or furniture that can fall on you.
4. Stay away from windows. In a high-rise building, expect the fire alarms and sprinklers to go off during an earthquake.
5. If you are outdoors, find a clear spot away from buildings, trees, and power lines. Drop to the ground.
