Large earthquakes can have hundreds to thousands of instrumentally detectable aftershocks, which steadily decrease in magnitude and frequency according to a consistent pattern. In some earthquakes the main rupture happens in two or more steps, resulting in multiple main shocks. … small plastic halloween batsWebAn aftershock is a small earthquake that echoes or follows a larger one.
