2.2 causes earthquakes 2.2.1 natural earthquake The earthquake is a natural disaster, a type of Earth phibat. Most of the time is a natural phenomenon.Caused by the vibration of the ground due to release energy to thermal stress. Accumulated within the world come out suddenly to balance of crust. Usually caused by the movement of the fault within the crust layer at the outside of the structure.Parts of the world. There is a movement, or change slowly to date (see the movement of plate tectonics). Earthquakes occur when stress resulting from too many changes. This condition occurs often.Around the perimeter of the plate tectonics Divided into lithosphere crust layer (the Lithosphere). Calling the earthquake occurred the area perimeter of the plate tectonics earthquakes between the sheets. (Interplate earthquake), which often occurs over the earthquake and severe internal plate (Intraplate earthquake). 2.2.2 the 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 includes nuclear waste is stored underground, etc.-The creation of a large reservoir and dam, which may be experiencing earthquakes due to the weight of the water.In the dam to release energy. Causes of stress conditions in the area.Changed as well, making the water pressure. Resulted in a cumulative resistance power stones Most of the time will be at the Center are at 5-10 km depth reporting earthquakes like this.Hoover Dam, the country has been the United States, but violent when 2488 (1945) little. A check dam BA services-Zimbabwe When Thomas Creek dam, da-2502 (1959) Country Greece When 2506 (1963) and.The violence caused by the dam, a forward of. In the country of India When 2508 (1965) which reaches 6.5 a course. They were killed more than 180 people.-Deep-level mining Mining will have a stone might cause a vibration.-Pump ground water to pump underground water brought up using too much oil, and pump, as well as natural gas.
