| Summary: | The strain release curve of the aftershock sequence of the great Assam earthquake of August 15, 1950 exhibits three linear segments. A secondary aftershock sequence has also been reported; the strain release curve in this case is also linear. The b value, using the maximum likelihood method of Utsu, for the sequence is 0.52 ± 0.095. The fault plane solution shows that the fault strikes almost cast-west and dips northward at an angle of 80°; the motion is predominently strike slip (right lateral type). The spatial distribution of aftershocks shows two main centers of activity at the two ends of the probable fault. |
