Abstract

This paper presents the focal mechanism solution of the Nepal·Bihar earthquake of August 20, 1988. Use was made of the first motions of P waves and polarization (or first motions) of S waves. The mechanism solution is characterized by a predominent component of strike-slip faulting. The deduced orientation of the axis of compression is nearly north·south. This orientation of the axis of compression is in agreement with the axis of compression deduced from the mechanism studies for Himalayan earthquakes.

Abstract

This paper presents the focal mechanism solution for the Burma-India border earthquake of August 6, 1988. Use was made of the first motions of P waves and polarization (or first motions) of S waves. The mechanism solution is characterised by a predominant component of thrust faulting. The deduced orientation of the axis of compression is northeasterly. This orientation of the axis of compression is nearly parallel to the trend of tectonic features in the epicentral region of this event.
