1 Answer

Answer :

Earthquake: An earthquake is the result from the sudden release of stored energy due to abrupt dislocation and disturbances within its interior causes the sudden vibrations (shaking) of the earth’s crust that creates seismic waves. Its result is displacement of ground, destruction of property, causes tsunamis.

Classification of Earth Quake based on origin:

1. Techtonic Earth Quake: Earth Quake originated due to relative movement of crustal block or faulting.

2. Non-techtonic Earth Quake: Earth Quake originated due to volcanic eruption, atomic explosions, Landslides, avalanches.
