Question

causes of earthquake ​

Answer 1

CAUSES OF EARTHQUAKES ARE:

Earthquakes are caused by a sudden release of stress along faults in the earth's crust....

Answer 2

Answer:

Earthquakes are caused by sudden tectonic movements in the Earth’s crust. The main cause is that when tectonic plates, one rides over the other, causing orogeny collide (mountain building), earthquakes. The largest fault surfaces on Earth are formed due to boundaries between moving plates.

The stress increases when they stick, relative motion between the plates. This continues until the stress rises and breaks, suddenly allowing sliding over the locked portion of the fault, releasing the stored energy as shock waves. Such faults are San Andreas fault in San Francisco, Rift valley in Africa etc.
