Abstract

The time-distance curves, plotted from the first onsets of P-waves, recorded by the coastal seismograph stations for the earthquakes originating from the Bay of Bengal and Andaman and Nicobar Islands, indicate a single layered crust in this region. The depth to the Moho has been determined as 25.4 km. The velocities at the upper layer and at the top of the mantle have been determined as 6.28 ± 0. 04 and 7.97 ± 0.01 km/sec respectively. The granitic layer was found totally absent.
