Earthquakes are recorded by instruments called seismographs.the recording they make is called a seismogram.the seismograph has a base that sets firmly in the ground, and a heavy weight that hangs free.when an earthquake causes the ground to shake, the base of the seismograph shakes too, but the hanging weight does not.

The duration of an earthquake is related to its magnitude but not in a perfectly strict sense.there are two ways to think about the duration of an earthquake.the first is the length of time it takes for the fault to rupture and the second is the length of time shaking is felt at any given point (e.g.when someone says quoti felt it shake for 10 secondsquot they are making a.

Earthquakes happen when two large pieces of the earths crust suddenly slip.this causes shock waves to shake the surface of the earth in the form of an earthquake.where do earthquakes happen? earthquakes usually occur on the edges of large sections of the earths crust called tectonic plates.these plates slowly move over a long period of time.
