GEOLOGY

Detailed explanation-1: -Aftershocks are smaller earthquakes that occur in the same general area during the days to years following a larger event or “mainshock.” They occur within 1-2 fault lengths away and during the period of time before the background seismicity level has resumed.

Detailed explanation-2: -"In any earthquake, a certain amount of stress is released, but in large earthquakes not all the stress is released in one earthquake and then each and every aftershock releases more and more stress. And that is why, for any major earthquake with a large fault, many, many aftershocks will follow, ” she said.

Detailed explanation-3: -An earthquake large enough to cause damage will probably produce several felt aftershocks within the first hour. The rate of aftershocks dies off quickly. The day after the mainshock has about half the aftershocks of the first day. Ten days after the mainshock there are only a tenth the number of aftershocks.

Detailed explanation-4: -: an aftereffect of a distressing or traumatic event. : a minor shock following the main shock of an earthquake.

Detailed explanation-5: -But what is the difference? The difference is in the intensity of the quake. The initial quake always has the greatest power, or magnitude, as defined by the Richter scale. Aftershocks are smaller quakes that then occur in the general area after the main quake.
