Earthquake in Chile Essays Earthquake in Chile Essay Earthquake in Chile Essay Earthquakes The motion of the Earth s tectonic home bases causes temblors. Earthquakes occur where home bases meet along home base boundaries. F.e when two home bases move towards each other, one home base can be pushed down beneath the other home base, into the mantle: this is a subduction zone. If this home base gets stuck under the other one, it causes a batch of force per unit area on the environing stones. When this force per unit area will be released it will bring forth daze moving ridges. These daze moving ridges are called seismal moving ridges. This is what we call an temblor. Plate boundaries The topographic point where two or more home bases meet, is known as a home base boundary. There are four types of home base boundaries: constructive, destructive, conservative and hit home base boundaries. About all temblors occur near to plate boundaries. Earthquake in Chile The temblor in Chile was caused by subduction. At the west seashore of Chile, three tectonic home bases meet: Antarctic home base, South American home base and the Nazca home base. Chile is located at a convergent home base boundary ( a destructive home base boundary ) . The Peru-Chile trench is caused by the subduction of the pelagic Nazca home base under the Continental South American Plate. This motion causes seismicity and volcanism in Chile, bring forthing astonishing temblors. This is a typical illustration of a continental-oceanic subduction zone. This temblor was the biggest 1 that hit Chile in over 50 old ages. Measuring temblors The magnitude of an temblor is measured with a seismometer. This machine measures motions in the surface of the Earth. The Richter graduated table steps earthquakes on a logarithmic graduated table. This means that an temblor of 5 is ten times more powerful than one of 6 on the graduated table of Richter. Most people express the magnitude with this graduated table. The 2010 Haiti temblor had a ruinous magnitude of 7.0.The Chile temblor was measured 8.8, this means there is about a widespread devastation. It was one of the strongest temblors that were of all time recorded. If we must believe Chilean governments, over 300 people have been killed. Richter Scale: Magnitude Damage 4 This magnitude temblor is widely felt and is strong plenty to check plaster. 5 A strong quiver shakes the Earth, damaging chimneys and weak edifices. 6 This temblor is strong plenty to severely damage mean edifices. 7 This temblor is strong plenty to destruct even good built constructions. 8 Even particular, earthquake-resistant edifices will be severely damaged. 9 There is widespread devastation. History of temblors Chile is a really active home base boundary, so it s a perfect topographic point for temblors. Chile is located in the alleged Ring of fire, an country in the Pacific where there are a batch of temblors and volcanic eruptions. The names of the home bases are in white. You can see the Nazca home base is doing subduction ( bluish line with trigons ) , because it goes under the South American home base ( Am A ; eacute ; rique du Sud ) . Tsunami Yes, there is a opportunity on a tsunami The temblor happened near a home base boundary. Because of home base tectonics, one home base can drop deeper, so there becomes a difference in sea degree.
