Earthquakes
Earthquake or tremor is a natural phenomenon, which is a vibration or a series of concussive vibrations of the Earth’s surface that occur in a time not exceeding a few seconds, which is caused by the movement of rock plates in the Earth’s crust. , This is due to the breaking and displacement of rocks due to the accumulation of internal stresses as a result of geological influences that result in the movement of the Earth's plates. Seismic activities exist at the boundary level of rocky plates. The earthquake arises as a result of volcanic activities or as a result of glides in the crust layers.
Earthquakes lead to cracking the ground and depletion of springs or the emergence of new springs or the occurrence of highs and lows in the Earth's crust as well as high waves under the sea (tsunami), as well as the disruptive effects of buildings, transportation and installations. Asthenosphere is most often caused by convection movements that move the continental plates, causing tremors. Also, earthquakes may cause great devastation.
