This released energy creates some powerful and seismic waves which travels ferociously through the surface of the earth, and with the help of a seismometer the type, size, waves frequency of the earthquake is measured.

This produces enormous amount of heat and energy within the crust of the earth, which may also initiate very severe earthquakes. When the steam expands and dashes to come out, the earth is violently shaken. It is a very common thing on many parts of the earth.
