Abstract

Abstract The Indo-Burman arc occupies a unique position in the geotectonic framework of Southeast Asia. It sweeps in a broad curve from the southern tip of the Mishmi and forms a boundary between India and Burma with high rising mountainous regions. The occurrence of a narrow belt of ophiolitic rocks in association with radiolarian cherts and pelagic sediments along the arc has great significance in terms of plate tectonics. Furthermore, the occurrence intermediate depth earthquakes analogous to an island arc adds more significance. The present paper is an attempt to correlate the present day seismic activity with a probable progressive geodynamic evolution of the arc.
