a The magnitudes of the observed aftershocks as a function of time after the mainshock (in days) and b the modeled (purple line) and observed (blue circles) temporal distribution of the seismicity rates for the Pasaman earthquake aftershock sequence. The modeled distribution was obtained using the modified Omori’s law (Utsu 1961) through regression of the observations. The standard deviation of the regression is shown in dashed grey lines. The background seismicity rate was evaluated according to the seismicity 3 years before the Pasaman earthquake (dashed blue line)
