But in most earthquake sequences, the sum of the aftershock seismic moments rarely exceeds 10% of the mainshock moment. For a typical shallow interplate M S = 7.0 earthquake, thousands of small aftershocks may occur.

Unlike other major earthquakes, which have one main shock and several subsequent aftershocks, swarms lack a clear mainshock event. The causes of long-lasting earthquake swarms are not sufficiently understood. fish hooks disney gameIn seismology, an aftershock is a smaller earthquake that follows a larger earthquake, in the same area of the main shock, caused as the displaced crust adjusts to the effects of the main shock. Large earthquakes can have hundreds to thousands of instrumentally detectable aftershocks, which steadily decrease in magnitude and frequency according to a consistent pattern.
