GEOLOGY

Detailed explanation-1: -Maps. Earthquakes occur when two tectonic plates of Earth’s crust slide past each other along a fault. Earth’s plates are always moving, which causes a build-up of friction and tension. When that energy releases suddenly, an earthquake occurs.

Detailed explanation-2: -Earthquake: A sudden slipping or movement of a portion of the earth’s crust, accompanied and followed by a series of vibrations. Epicenter: The place on the earth’s surface directly above the point on the fault where the earthquake ruptures began.

Detailed explanation-3: -Earthquake is shaking of the earth’s surface caused by the 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 seismic waves.

Detailed explanation-4: -Earthquakes occur in the crust or upper mantle, which ranges from the earth’s surface to about 800 kilometers deep (about 500 miles).
