Effect of Plate Tectonics: Plate tectonics extend a significant contribution in the origination of earthquakes because various plates are found under the earth’s surface. In these plates, deviation and convergence take place around the edges of the plates and they shift towards the left and right. The turbulence which occurs due to the changes in the earth’s crust assists in the originate of earthquakes.
Human Contribution: Impact of human activities also plays a significant role in the origination of earthquakes. Various such activities are done by humans, which assist in emergence of conditions of earthquake. Human activities such as nuclear explosions, explosions done to blow off the rocks in mining areas, deep drilling and dams with massive volume of water built by humans increase the possibility of originatation of earthquakes. Heightening of the edges of mines or their falling down during the process of mining also give rise to origination of earthquake.
