May 6, 2024 · An earthquake is the sudden movement of Earth’s crust at a fault line. This photograph shows the San Andreas Fault, a 750-mile-long fault in California. Credit: Public Domain. The location where an earthquake begins is called the epicenter. An earthquake’s most intense shaking is often felt near the epicenter.

May 12, 2024 · earthquake, any sudden shaking of the ground caused by the passage of seismic waves through Earth ’s rocks. Seismic waves are produced when some form of energy stored in Earth’s crust is suddenly released, usually when masses of rock straining against one another suddenly fracture and “slip.”. Earthquakes occur most often along geologic ...
