WebAn aftershock is a smaller earthquake that occurs after a previous large earthquake, in the same area of the main shock. If an aftershock is larger than the main shock, the aftershock is redesignated as the main shock and the original main shock is … Webmain shock and its largest aftershock m = m m –m a,max (1) and the ratio R between the seismic moment released by all aftershocks and the main shock. For the latter, we use the formula M(m)=109.1+1.5m [Hanks and Kanamori, 1979] and calculate the seismic moment released by the main shockP M m = M(m m), before-main shock activity M f = i:ti glendale high school springfield
