The earthquake is second nature, causing serious damage to life and property of the man believed to have been a wide area all countries affected by the catastrophe, whether directly or indirectly, At present, it was found that an attempt has been made in many countries. That danger from earthquake. Study and understand the mechanisms of earthquakes to forecast earthquake and predict events that would occur when? where? Size?, but it has not succeeded, so. So now there is no one can predict earthquakes. In General, what is needed for the earthquake danger was prepared well, but individual countries should have measures to prevent and mitigate disasters earthquake, both in the short and long term, such as studies about the nature of the origin of the different fault earthquake.Awareness and precautions against earthquakes, when the people, being divided into the earthquake zone, as appropriate, of the risks. Legislation, building construction can accept earthquakes as appropriate for each vulnerable area. There is a great deal of planning. If serious damage after earthquakes, etc. In the case of the countries of Thailand, although geography location is located in the area of earthquake risks are low, but so is not to. Department of meteorology and the related agencies have conducted activities to supplement the above measures, with the mission to earthquake measuring 24 hours exchange of information between countries on a regular basis, as well as the establishment of a planning project for disaster reduction from earthquake which may be harmful to the public. The earthquake is second nature. Caused by the movement of the crust suddenly The majority of earthquakes often occur at the edges of crust are earthquakes of the world. Such movement occurs because molten rock layers under the crust. Get the heat and float push the crust all the time. Make each piece of crust are moving in a different direction with the accumulated energy within edge of crust is the best collision friction coating or separately any piece of crust's edge hakboriwen. Do not pass on or near any country a country, it would have a high risk of earthquake disasters. For example, a country Japan The Philippines. Country Indonesia New Zealand, etc. In addition, the energy accumulated in the crust Passed to the floor of the continental crust At the rock's cracks under the surface of the Earth called the "fault" when the plane cracked at the same compression splice is large, the fault is a sudden earthquake occurred. แผ่นดินไหวเป็นปรากฏการณ์ธรรมชาติที่เกิดจากการเคลื่อนที่ของแผ่นเปลือกโลก (แนวระหว่างรอยต่อธรณีภาค)ทำให้เกิดการเคลื่อนตัวของชั้นหินขนาดใหญ่เลื่อน เคลื่อนที่ หรือแตกหัก และเกิดการโอนถ่ายพลังงานศักย์ผ่านในชั้นหินที่อยู่ติดกัน พลังงานศักย์นี้อยู่ในรูปคลื่นไหวสะเทือน จุดศูนย์กลางการเกิดแผ่นดินไหว (focus) มักเกิดตามรอยเลื่อน อยู่ในระดับความลึกต่างๆของผิวโลก เท่าที่เคยวัดได้ลึกสุดอยู่ในชั้นแมนเทิลส่วนจุดที่อยู่ในระดับสูงกว่า ณ. ตำแหน่งผิวโลก เรียกว่า "จุดเหนือศูนย์กลางแผ่นดินไหว" (epicenter)การสั่นสะเทือนหรือแผ่นดินไหวนี้จะถูกบันทึกด้วยเครื่องมือที่เรียกว่า ไซส์โมกราฟ
