GEOLOGY

Detailed explanation-1: -aftershock, any of several lower-magnitude earthquakes that follow the main shock of a larger earthquake.

Detailed explanation-2: -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-3: -Aftershocks can continue over a period of weeks, months, or years. In general, the larger the mainshock, the larger and more numerous the aftershocks, and the longer they will continue. Foreshocks are relatively smaller earthquakes that precede the largest earthquake in a series, which is termed the mainshock.

Detailed explanation-4: -This is known as a seismogram. The bigger the quake the larger the size or amplitude of the waves recorded. In general, a magnitude 3 earthquake is about the smallest that one can feel.

Detailed explanation-5: -Aftershocks are a sequence of earthquakes that happen after a larger mainshock on a fault.
