Defination and Overview of Earthquake ?.

An earthquake is a natural phenomenon that results from the movement of tectonic plates. It is caused by the release of energy stored in the Earth's crust, which creates seismic waves that travel through the ground and cause the ground to shake. Earthquakes can range in magnitude from small, barely noticeable tremors to massive, destructive events that can level entire cities. The severity of an earthquake depends on a number of factors, including the size of the fault that caused the quake, the depth of the earthquake, and the type of soil and rock near the surface. Earthquakes can have a significant impact on communities, causing damage to buildings, infrastructure, and natural landscapes, as well as leading to loss of life and injury.
