Earthquake is a phenomenon of vibration or shaking of the earth's surface. In order to adapt in the equilibrium. The earthquake can cause damage and disaster to the country living creatures.By an earthquake, some characteristics can be caused by human activities. But with less violence occurring from nature. Geologists estimated that in one day. To earthquakes, about 1000 times, most of which will be an earthquake vibration only only lightly คนทั่วไปไม่รู้สึก
.Earthquake is a natural phenomenon caused by the motion of the plates. (the joint lithosphere). The movement of a large rock sliding moving or breaking the โอนถ) potential energy.This potential energy in the form of seismic
.
.Hypocenter usually follow the move in different depths of the earth's surface ever measured deep in the mantle. The point is higher than the level at the earth's surface, called the epicenter.Called the seismology. When the epicenter of large earthquakes is off the coast. Potential tsunami followed. In addition, earthquakes may also cause landslide And sometimes volcanic activity followed
.
.The earthquake measured by observation from recycle Mo meter (seismometer) moment magnitude scale is exchange most used the world reported the quake with a magnitude of more than about 5 for another earthquake of magnitude smaller, 5Or call the Richter scale, two section with a range of similar accuracy in numerical order. The earthquake size 3 or lower most hardly feel or feel very light. While earthquakes ranging in size 7.Depending on the depth. The largest earthquake in the history is more than 9 slightly. Although there is no limit to how much be that size A massive earthquake last sizes 9.0 or more is 9 earthquake.0 Japan last year 2554 and the largest earthquake ever recorded in Japan. The intensity of the vibration measured by modified Mercalli intensity scale. If other parameters constant.
