The stress drop and average dislocation of some earthquakes in the Indian sub-continent

The stress drop and average dislocation of some earthquakes in the Indian sub-continent have been determined after deducing the relationship between the aftershock areaA, and the magnitudeML of the main shock which is given by $$\log A = 0.89M_L - 2.67 for 5 \leqslant M_L \leqslant 7.$$
