An earthquake (also known as a quake, tremor or temblor) is the result of a sudden release of energy in the Earth's crust that creates seismic waves. The seismicity, seismism or seismic activity of an area refers to the frequency, type and size of earthquakes experienced over a period of time.At the Earth's surface, earthquakes manifest themselves by shaking and sometimes displacement of the ground. When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause a tsunami. Earthquakes can also trigger landslides, and occasionally volcanic activity.

In its most general sense, the word earthquake is used to describe any seismic event — whether natural or caused by humans — that generates seismic waves. Earthquakes are caused mostly by rupture of geological faults, but also by other events such as volcanic activity, landslides, mine blasts, and nuclear tests. An earthquake's point of initial rupture is called its focus or hypocenter. The epicenter is the point at ground level directly above the hypocenter.

What we call earth quakes it a shake or shook on the surface of the earth .This process it is happen 24/7 none stop .That mean we have earthquake each second ,but amount of the shook wave that it's absorb on the surface it's low ,unless there be an unwanted cause that resist against other tectonic plate ,at that time pressure of the two tectonic at point of the slide during release it cause big shook that wave of the shook it transfer large amount of the energy in to the surface .

Another process of the Earthquake are volcanic activities ,which during this process cause of the extreme temperatures differential from hot to cold an explosion sound it accrue and it cause shook wave that it shake the surface around the out coming of the volcanic activities .

Another process of earthquake is clasps ,when in a point under the outer lay it get empty ,the upper lay it brake down and it case large cracks or canyons ,which this type of the earth quakes does have short shook ,mean surface it is not shake it just move up or down and time of the quake is very fast .

Another type of the earth quakes are man made explosions , like Atomic tests .

Another type of the earthquakes are asteroid impacts .

The Earth can be compared to an apple - the Earth's crustin comparison to Earth is as thin as is the outer covering of an apple compared to an apple. It is made up of parts like a human skull and the float/buoy over the inner molten magma so the parts called tectonic plates can slide when the collide at 180 degrees mountains are formed. As and when some interlock is there, the plates keep on applying sliding or pulling or pushing force and when the force becomes large enough the interlock gives away and a shock wave called earthquake is generated which can also be associated with exlpulsion of magma called volcanic eruption

on a divergent plate boundary... the plates move apart... like in the mid atlantic

on a convergent plate boundary... the plates move together... like india-asia

on a transverse plate boundary... the plates move past each other... like san andreas fault

Source(s): i am a geology major this was covered in a chapter of my GEOL 100 class... i got 100% on the quiz and test of this topic
