Earthquake or earthquake tremors are sudden and passengers that take place on the Earth's surface caused by underground shocks of rocky plates of the Earth's crust to 300 m below ground. Other reasons are considered gas offsets (mainly methane) and volcanic activity. There are two types of earthquakes: The naturally occurring and induced.
The majority of earthquakes are of natural origin Earth, called tectonic earthquakes. The strength of tectonic plates slide on the atmosphere may move away, collide or slide into one another. With these forces the rocks will changing to its yield point, after which the rocks begin to break down and release accumulated energy during the elastic process. The energy is released through seismic waves on the surface and inside the Earth.
It is estimated that more than 10% of the energy is reproduced by an earthquake seismic waves. There are also induced earthquakes, which are compatible to human action. Originate from explosions, extraction of minerals, water or fossil, or even by falling buildings; but have much lower magnitudes of tectonic earthquakes.
The consequences of an earthquake are:
• Soil Vibration,
• Fault Opening
• Landslide,
