| What causes an earthquake? An earthquake is caused by rocks moving underground. The surface of the earth is made up of about 20 huge plates. The plates are thousands of miles wide and many miles thick. Like turtles with their shells, they carry oceans and continents right on their backs. All the earth's plates are constantly in motion, although they move very slowly, maybe an inch a year. They push each other, trying to slip under or over each other, or to slide past one another. Earthquakes often happen when two plates come together. Along the plates where the plates meet, there is a kind of crack in the earth's surface called a fault. The most famous fault in the United States is the San Andreas Fault, which runs 600 miles through California and is more than 30 million years old. An earthquake happens along a fault where two plates rub together while moving in different directions. The earth shakes and shivers and vibrates like a rubber band that's been snapped. Those vibrations are picked up by an instrument which enables experts to figure out where the earthquake occurs and how strong it is. Scientists measure an earthquake's strength by what they have named the Richter Scale. The Scale runs from zero to nine, with nine being the most powerful. Sometimes an earthquake occurs so far below the surface, we can hardly feel it on top. Sometimes an earthquake is so strong that it has more power than a nuclear explosion. An earthquake can last five seconds or up to ten minutes and create enough heat to melt any rock.
