What are earthquakes?The earthquake is a vibration of the Earth signs. The severity of this vibration since humans don't feel up to stage of erosion damage to buildings, houses. Dam, roads, etc.The cause of the earthquake.The cause of the catastrophe caused by the movement of the crust. (Earth crust) because the crust is primarily composed of phaen (plates), a virtual jigsaw puzzle to live within the world there is a very high heat, causing the circulating flow (convection), Manchester's Donington (mantle) crust animation 3 features.1. collision (convergent plates). 2. a separate fee or other (divergent plates).3. movement in friction coating (transform plates). When the crust caused movement, regardless of whether one or a mixture of styles which will cause cracks of crust or stone (fault) and the explosion of the volcano, which causes the accumulation of kinetic energy (kinetic energy) in the crust and this energy is released and processed into heat energy, and return to Parliament until all those balanced. But during the accumulation of power, there will be a strong geological configuration variable (tectonic force) and produces a wave, earthquake (seismic waves) Spread out in all directions all the way from the first point, which causes the accumulation of energy and the energy is released to the. (Earthquake focus) earthquake waves that spread out and this causes vibrations and destruction due to the. The waves of earthquake motion characteristics of several complex plane makes the crust of earthquake waves through the resulting vibration motion distortion or erosion which damages it more or less depends on the. The energy is released that is so much less?There are also other reasons that could have caused a catastrophe, but it is not a major cause and a chance to bat, very little occurred, such as a check, Udon West. A nuclear bomb or explosive experiments etc etc.A measure of the severity of the earthquake. The intensity of the earth do two ways. 1. measure the size (magnitude) of the energy is released, which can be calculated from the tracking characteristics of khluen earthquakes by measuring earthquake (seismograph). This gauge called Richter between seale (less severe) 1.0 to 9.0 (very severe). 2. the measure of intensity (intensity) of the violence shaking at somewhere which will come out in a way the severity of shaking that humans feel that how much or damage of various construction. There is much this gauge size 1 seale called Mercalli-12th.Earthquake occurs where? Because the cause of the motion of the plate tectonics. So where will the earthquake, it is located at the boundaries of the plate tectonics, the Pacific Ocean, around the edges, or known as the Ring of Fire area in San klangomhatmuthon Atlantic (Mid-Atlantic Ridge), isolation and an area from India Italy Greece and Turkey countries.
