An earthquake (or quakes, tremors) is the shaking of the surface of the earth, caused by the sudden movement in the Earth's crust. They can be extremely violent or cannot be felt by anyone.
Earthquakes are usually quite brief, but may repeat. They are the result of a sudden release of energy in the Earth's crust. This creates seismic waves, which are waves of energy that travel through the Earth. The study of earthquakes is called seismology.[1]Seismology studies the frequency, type and size of earthquakes over a period of time.
There are large earthquakes and small earthquakes. Large earthquakes can take down buildings and cause death and injury. Earthquakes are measured using observations from seismometers. The magnitude of an earthquake, and the intensity of shaking, is usually reported on the Richter scale. On the scale, 3 or less is scarcely noticeable, and magnitude 7 (or more) causes damage over a wide area. Earthquakes are caused by tectonic movements in the Earth's crust. The main cause is that when tectonic plates , one rides over the other, causing orogeny collide (mountain building), earthquakes.
The boundaries between moving plates form the largest fault surfaces on Earth. When they stick, relative motion between the plates leads to increasing stress. This continues until the stress rises and breaks, suddenly allowing sliding over the locked portion of the fault, releasing the stored energy as shock waves. Such faults are San Andreas fault in San Francisco , Rift valley in Africa etc There are four different types of earthquakes: Tectonic, volcanic, collapse and explosion.
1.A tectonic earthquake is one that occurs when the earth's crust breaks due to geological forces on rocks and adjoining plates that cause physical and chemical changes.
2.A volcanic earthquake is any earthquake that results from tectonic forces which occur in conjunction with volcanic activity.
3.A collapse earthquake are small earthquakes in underground caverns and mines that are caused by seismic waves produced from the explosion of rock on the surface.
4.An explosion earthquake is an earthquake that is the result of the detonation of a nuclear and/or chemical device.
