The release of stored clastic energy caused by sudden fracture and movement of rocks inside the Earth. Part of the energy released produces seismic waves, like P, S, and surface waves, that travel outward in all directions from the point of initial rupture. These waves shake the ground as they pass by. An earthquake is felt if the shaking is strong...

Is a sudden motion or trembling in the Earth. The motion is caused by the quick release of slowly accumulated energy in the form of seismic waves. Most earthquakes are produced along faults, tectonic plate boundaries, or along the mid-oceanic ridges.

An earthquake is shaking on Earth's surface, caused by sudden movement in Earth's crust. This crust is made up of many pieces called tectonic plates. Faults are associated with, or form, the boundaries between these plates. In an active fault, the pieces of Earth's crust along the fault move over time. The moving rocks can cause earthquakes.The tow...
