Subcritical and supercritical regimes in epidemic models of earthquake aftershocks
Subcritical and supercritical regimes in epidemic models of earthquake aftershocks
We present an analytical solution and numerical tests of the epidemic-type aftershock (ETAS) model for aftershocks, which describes foreshocks, aftershocks and mainshocks on the same footing. The occurrence rate of aftershocks triggered by a single mainshock decreases with the time from the mainshock according to the modified Omori law K/(t+c)^p …
