. Write causes of earthquake and explain briefly two hazards caused by earthquake.

Best Answer

Causes of earthquake are as follows:

1. Earthquake is caused by a disturbance deep inside the earth’s crust. 

2. The movement of plates, whose boundaries are the weak zones called fault zones, also causes earthquakes.

3. Nuclear explosion and volcanic activities are also cause earthquake.


Earthquake can cause immense damage to buildings, bridges, dams and people. There can be a great loss to life and property. The earthquakes can cause floods, landslides, tremor and tsunamis.


Tsunami is a sea wave of local or distant origin that results from large-scale seafloor displacements associated with large earthquakes, major submarine slides, or exploding volcanic islands.


The tremors are caused by the disturbance deep down inside the uppermost layer of the earth called the crust. The tremors produce waves on the surface of the earth. These are called seismic waves. An instrument called seismograph records the waves.
