Earthquake
Earthquake is the shaking of the surface of earth, that results to produces seismic wave. There have a certain cause of happening of earthquake. Basically, due to releasing of energy from earth causes earth quake. Due to releasing of energy in huge amount appears in certain phenomenon. Such as seismic wave. Seismic wave may be the transformed form of energy. Seismic wave is a form of energy that propagates along with soil and rock. This wave propagates in such way that the ocean wave propagates. Earthquake is also known as tremor of the earth. Two most common scale of measuring of earthquake is seismometer and Rickert scale. Both two scale is similar in function. Both are used to measuring the magnitude of earthquake. Scientists have discovered the few probable cause of earthquake When two heavy rock inside the earth undergo in friction or hit each other from the opposite side then an energy release that causes seismic wave. Another different cause may have to cause eart
