An earthquake is when the ground shakes uncontrollably causing damage to buildings, roads and housing structures. This happens when two pieces of earth slip over one another. The area where this slip occurs is called a fault line. The area under the surface of the earth where the earthquake takes place is called the hypocenter, and the area above this place is called the epicenter.
In some cases a seismic tremor has foreshocks. These are littler quakes that happen in the same place as the bigger tremor that takes after. Researchers can 't tell that a seismic tremor is a foreshock until the bigger quake happens. (USGS, pg 3). The biggest, principle quake is known as the mainshock. Mainshocks dependably have consequential convulsions that take after. These are more modest tremors that happen thereafter in the same place as the mainshock. Contingent upon the span of the mainshock, post-quake tremors can proceed for a considerable length of time, months, and even years after the mainshock.
The earth has four significant layers: the inner core, outer core, mantle and crust. The crust and the highest point of the mantle make up a dainty skin on the surface of the planet. Anyhow this skin is not all in one piece it is made up of numerous pieces like a puzzle covering the surface of the earth. (USGS, pg 3). That, as well as these puzzle pieces keep gradually moving around, sliding past each other and catching one another. Scientist call these puzzle pieces tectonic plates, and the…
