Energy Released by Earth
No other natural force compares in sheer power with earthquakes. They represent enormous and nearly instantaneous releases of energy that can tear apart the landscape, leaving fault scarps like the one before you. Inherently unpredictable, earthquakes can rumble to life in areas where none had been known before. The energy released by the earthquakes travels through the Earth in waves. These waves can be destructive, but they also provide essential information about the Earth’s interior.

Subduction zones are places where two of the Earth’s plates collide, with one descending beneath the other.
The great San Francisco earthquake produced a surface rupture some 300 kilometers long.
Seismologists have long sought ways to predict earthquakes, but so far no reliable methods have been found.
The 1,200-kilometer-long San Andreas fault zone is part of the boundary between the Pacific and North American plates, and thus is known as a transform fault.
Earthquakes happen all the time because of the slow but continuous motion of the lithosphere.
