Earthquake is defined as “ a series of vibrations induced in the earth 's crust by the abrupt rupture and rebound of rocks in which elastic strain has been slowly accumulating.” in dictionary.com. In other word earthquake is crust release energy caused by shaking and plate tectonics are suddenly move.It may cause people injuryed and economic losses.
Earth 's surface crust is called lithosphere. The earth 's crust ruptured by the force of dislocation caused by rapid surface vibrations called seismic or damage. Tectonic activity caused by the earthquake called tectonic earthquakes; volcanic activity caused by the earthquake called volcanic earthquakes; seismic solid rock is called subsidence earthquake caused the collapse. Earthquakes are a common and ordinary and a natural phenomenon, but not intuitive and complex tectonic earthquake area, particularly with regard to seismic tectonic earthquakes occur and how it is conceived. Scientists think caused earthquakes are by the movement of tectonic plates.
How can we measure the size of earthquake? Scientists use Richter magnitude scale to know the earthquake release how many energy. Richter magnitude is rating to earthquakes based on the strength and duration of their seismic waves. They are classified from one to ten and recorded on seismographs. A quake of 3, people can feel; a quake of 5, some building has been damaged; a quake more than 7, building will be destroyed.“The largest recorded earthquake in the world was a…
