Abstract

The seismic data from 1999–2008 used in this study was acquired from a 5 station Digital Seismic Network in Kumaun Himalaya. The hypocentral parameters of the events used here indicate low stress drop values and shallow focal depth. The clusters of the epicenters of the events are very close to the Main Central Thrust (MCT), in between Munsiari Thrust (MT) and Berinag Thrust (BT). The neotectonic investigations were carried out in the major river valleys of the Kumaun Himalaya. From the investigations some new faults are identified on the basis of geomorphological signatures. The morphotectonic development has been related to the prevalent seismicity of the region. It is evident that the major thrust and faults of the region are seismically as well as neotectonically active in some segments. From the ongoing seismic and neotectonic movements it is clear that some of the faults and thrusts are active at present.
