These events occurred in the Indochina border region where a low-angle thrust fault accommodates motion between the underthrusting Indian plate and overlying Himalaya. The focal depths of all these earthquakes are between 12-37 km. The total range in dip for the three events is 5°-20°. TheT axes are NE-SW directed whereas the strikes of the northward dipping nodal planes are generally parallel to the local structural trend. The total source durations have been found to vary between 5-6 seconds. The average values of seismic moment, fault radius and dislocation are 1.0-11.0×1025 dyne-cm, 7.7-8.4km and 9.4-47.4 cm, respectively whereas stress drop, apparent stress and strain energy are found to be 16-76 bars, 8.2-37.9 bars and 0.1-1.7×1021 ergs, respectively. These earthquakes possibly resulted due to the tension caused by the bending of the lithospheric plate into a region of former subduction which is now a zone of thrusting and crustal shortening.
