An appraisal of aftershocks behavior for large earthquakes in Persia

Also we found a range for the difference between the magnitudes of the strongest aftershock and of the mainshock in each sequence, which varies from ∼0.9 (ISC) to ∼1.27 (IGUT). Finally, the spacial distribution of the aftershocks corresponds reasonably well to the causative fault planes of earthquakes.
