Main causes of the earthquake are plate tectonics, volcaniceruption or anthropogenic activities like explosions, reservoir induced seismicity etc. There is arelease of huge amount of energy in the form of sound and seismic waves causing shaking of
earth’s surface.
The regions which are on the boundaries of the tectonic plates are more prone to earthquake. Chile, Japan, Philippines etc are prominent example where earthquake occur . The plate boundaries are in constant motion as a result of this at the boundaries of tectonic plates there is sudden release of energy. Volcanic eruptions also lead to release of energy.
