Answer
Earthquakes are caused by the strain in the earth's crust which in turn is a result of a number of factors. When the earth’s crust is unable to accommodate itself to the strain, it results in a sudden release of energy in the form of a sudden violent shock or an earthquake.
Earthquakes are caused by severe tectonic movement of plates, volcanic eruption forces, folding and faulting and man-made causes.
