Detailed explanation-1: -Earthquake refers to a sudden violent shaking and vibration of the earth’s surface resulting from underground movement along a fault plane or from volcanic activity. Earthquakes can cause serious destruction to property, injury to people and even death.

Detailed explanation-2: -An earthquake is a weak to violent shaking of the ground produced by the sudden movement of rock materials below the earth’s surface. The earthquakes originate in tectonic plate boundary.

Detailed explanation-3: -An earthquake is a trembling or shaking movement of the Earth’s surface. Earthquakes typically result from the movement of faults, quasi-planar zones of deformation within its uppermost layers. The word earthquake is also widely used to indicate the source region itself.

Detailed explanation-4: -Types of seismic waves created by an earthquake include P-waves and S-waves that travel throught the earth as well as surface waves, which can cause a lot of damage at the Earth’s surface. Courtesy of USGS.
