"The earthquake is a natural disaster caused by the vibration of the ground due to release energy to vent the stress accumulated in the world come out suddenly to adjust the balance of the crust, the cause of earthquakes, it has two types of Division one due to the actions of man, including the atomic bomb trial. A water catchment dam and blast of coal mining, etc. The second type is the natural catastrophe which has theoretical mechanism of earthquakes is acceptable in the current theory is that 2.The theory on expansion of the crust (Source Dilation theory), believes that the earthquake caused the crust to khotkhong to raise and when their sudden absence from power, thus relieving came out in waves, earthquake. The theory on the return of an object (the Elastic rebound theory) believed that the earthquake caused the vibration is the reason comes from the movement of the fault (Fault), so when one object is moving to the point, it's missing out, and the image is very bad with the liberation of energy out, and then return the object, it returns to original image. This theory supports the idea that there is a mechanism for earthquake origin relates directly and closely with the vertical scrolling with the power (Active Fault) that arise from the effects of variable shape of crust. (Plate tectonics) tectonics plate tectonics. A large number of approximately 12 sheets of both phaenomhatmuthon and continents, which are constantly moving, some plates are moving. Some plates move toward each other and address some of the complex motion scrape plates to overlie each other as results of tensile stress which accumulate within the crust.The cause of earthquakes Natural catastrophe แผ่นดินไหวจากธรรมชาติเป็นธรณีพิบัติภัยชนิดหนึ่ง ส่วนมากเป็นปรากฏการณ์ทางธรรมชาติที่เกิดจากการสั่นสะเทือนของพื้นดิน อันเนื่องมาจากการปลดปล่อยพลังงานเพื่อระบายความเครียด ที่สะสมไว้ภายในโลกออกมาอย่างฉับพลันเพื่อปรับสมดุลของเปลือกโลกให้คงที่ โดยปกติเกิดจากการเคลื่อนไหวของรอยเลื่อน ภายในชั้นเปลือกโลกที่อยู่ด้านนอกสุดของโครงสร้างของโลก มีการเคลื่อนที่หรือเปลี่ยนแปลงอย่างช้า ๆ อยู่เสมอ (ดู การเคลื่อนที่ของแผ่นเปลือกโลก) แผ่นดินไหวจะเกิดขึ้นเมื่อความเค้นอันเป็นผลจากการเปลี่ยนแปลงมีมากเกินไป ภาวะนี้เกิดขึ้นบ่อยในบริเวณขอบเขตของแผ่นเปลือกโลก ที่ที่แบ่งชั้นเปลือกโลกออกเป็นธรณีภาค (lithosphere) เรียกแผ่นดินไหวที่เกิดขึ้นบริเวณขอบเขตของแผ่นเปลือกโลกนี้ว่า แผ่นดินไหวระหว่างแผ่น (interplate earthquake) ซึ่งเกิดได้บ่อยและรุนแรงกว่า แผ่นดินไหวภายในแผ่น (intraplate earthquake) Earthquake from human actions. There are both direct and indirect, such as explosions. Mining The dam created a reservoir or near fault Mechanical works Traffic, etc. Earthquakes (earthquakes). What are earthquakes? The earthquake is a vibration of the Earth signs. The severity of this vibration from the Men do not 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 movement with 3 styles. 1. collision (convergent plates). 2. separate or different quantity (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.
