EARTH QUAKE REFERENCE FILES
EARTHQUAKE REFERENCE FILES Earthquake, shaking of the earth’s surface caused by
rapid movement of the earth’s rocky outer layer. Earthquakes occur when energy stored within
the earth, usually in the form of strain in rocks, suddenly releases. This energy is transmitted to
the surface of the earth by earthquake waves. The study of earthquakes and the waves they create
is called seismology. Scientists who study earthquakes are called seismologists. (
