Document Summary

Distinct earthquake zone that begins at an oceanic trench and slopes landward and downward into earth at an angle of about 30 to 60 . body wave. Seismic wave that travels through earth"s interior. depth of focus. Distance between the focus and the epicenter of an earthquake. earthquake. A trembling or shaking of the ground caused by the sudden release of energy stored in the rocks beneath the surface. elastic rebound theory. The sudden release of progressively stored strain in rocks results in movement along a fault. epicenter. The point on earth"s surface directly above the focus of an earthquake. focus. The point within earth from which seismic waves originate in an earthquake. intensity. A measure of an earthquake"s size by its effect on people and buildings. A type of surface seismic wave that causes the ground to move side to side in a horizontal plane perpendicular to the direction the wave is traveling. magnitude.
