An earthquake is a very powerful shake which sends out very powerful shockwaves that causes many building, deaths ect. The edges of the tectonic plate crack due to fractures. Most earthquakes occur along the edge of the oceanic and continental plates. The magnitude of any earthquake determines how big the impact of the earthquake is.

Most earthquakes occur along the edge of the oceanic and continental plates. The earth’s crust which is the outer layer of the planet is made up of several pieces called tectonic plates. The plates under the oceans tectonic plates are called oceanic plates and the rest are called continental plates. The plates are moved around by the motion of a deeper part of the earth (the mantle) that lies underneath the crust. These plates are always bumping into each other, pulling away from each other, or past each other. The plates usually move at a very slow speed. Earthquakes usually occur where two plates are running into each other or sliding past each other.

There were two magnificent earthquakes which happened one in Haiti and the other in Chile both of these earthquakes had a significant impact on their individual countries. Haiti had an earthquake measuring a magnitude of 7.0 on the Richter scale and Chile had an earthquake a measuring 8.8 on the Richter scale so as you can see according to these results Chiles earthquake had more of an impact on its country. The earthquake in Chile took place along 700km of the tectonic plate boundaries and the ground moved by an average of 10 meters. This rupture is very spread out, although the movement of the ground was very large.

Haiti’s capacity to cope was really awful, they were warned on a Friday night that they were going to have an earthquake but Haiti was struggling to cope also with a cholera epidemic that has killed many thousands deteriorating conditions in tent camps as aid groups withdrew from the improvised country. Due to lack of food, water and tents ect to give out when...
