Earthquake is the one of the most dangerous natural calamities. Any sudden shaking of the ground caused by the passage of seismic waves through the earth’s rocks. Earthquakes caused by a sudden release of violent gorund energy caused either by the shifting of the earth’s crust or magnetic activity.
A Body of rock that is under stress becomes deformed. When the rock no longer withstand the deformation, it breaks and the two sides past each other.
Earthquakes is very dangerous. Its damage to a man – made structure as well as an outbreak of fire and spilling of hazardous chemicals. Earthquakes are among the most natural hazards. They strike without warning and many of the earthquakes zones coincided with areas of high population density. When large earthquakes occur in such areas the results can be catastrophic, with terrible loss of human lives and untold economic cost.
There are many causes of earthquake.
1) Earthquake caused due to sudden lateral or vertical movements in the crust of the earth
2) It caused by human activity, like tunnel construction, filling reservoirs and implementing geothermal or fracking projects.
3) Earthquakes are caused by the sudden release of stress along faults in the earth crust. Continuous motion of the tectonic plates causes the steady build of pressure in the rock strata on both sides of the fault until stress is great enough, which is released in jerky and sudden movement.

Earthquake:-
Earthquake is a natural disasters.when the surface of the earth started shaking with a heavy vibration by the sudden realse of energy caused by volcanic and magmanetic incident, or the slip or the stress changes in the earth.
Earthquake causes many several damage and loss of lives. It can be dangerous and destructive. There are many several example of earthquake which is causes many harmful effects, like- 2011 Japan’s Great Sendai Earthquake, 2015 Nepal earthquake, 2004 Indian Ocean earthquake and tsunami. Earthquake can be causes other disaster like tsunami.
Earthquake causes:-
The plates in the earth sometimes started conflicting towards each other, run against each other and shake and rub each other which causes earthquake.
During the volcano come over many internal movement and vibration use to shake earths surface.
In the earth surface many dislocated part of earth moves up and down due to this incidents the earths surface started shaking which causes earthquake.
When the two plates in the earth meet it cause eearthquake.
In the eath’s crust when the rocks can not withstand the stress. they started breaking down and shift energy was realised which cause a several movement in earths surface, that called earthquake.
Earthquake can also caused by sudden volcano exploitation.
Sudden changes in earth surface is causes sudden vibration which causes earthquake.
Faluts and fracture in earth surface is caused earthquake.
Earthquake can be causes a massive destruction in the living kind.
The convergent boundaries has peculiarity like the Himalaya that some time neither of colling plates sink which causes earthquake.
