Summary
Elastic strain rebound increments for the Hindukush region has been studiedwhich revealed a cyclic pattern of strain release in this area where the rate of strain release decreases with time. The spatial distribution of earthquakes clearly defines the Pamir knot where most of the shocks are concentrated. The dip of the deep seated fault which produces the earthquakes so frequently comes out to be 54° dipping in the northwest direction. This fault is best developed between 70 to 300 kilometers and perhaps both these levels represent tectonic discontinuities.
