Question

What is Earthquake ?​

Answer 1

Answer:

An earthquake is an intense shaking of Earth’s surface. The shaking is caused by movements in Earth’s outermost layer.

Earthquakes are caused by a sudden release of violent ground energy caused either by the shifting of the earth’s crust or volcanic/magmatic activity. Most earthquakes occur when two sides of a fault slide past each other. The crust may either be being compressed, pulled apart, moving sideways or a combination of these. The resulting seismic waves are felt as earthquakes.

Answer 2

Answer:

An earthquake is the result of a sudden release of stored energy in the Earth's crust that creates seismic waves. ... Earthquakes may occur naturally or as a result of human activities. Smaller earthquakes can also be caused by volcanic activity, landslides, mine blasts, and nuclear experiments.
