SEISMOTECTONIC STUDY OF NW HIMALAYAS USING HYPODD
The geology of Himalayas is a record of the most dramatic and visible creations of the modern plate tectonic forces. The Himalayas which stretch over 2400 km are the result of an ongoing orogeny – the result of continent-continent collision of tectonic plates. An insight into the occurrence and processes related to earthquakes has always been challenging for earth science community. The study of these earthquakes is not only important for mitigating the seismic hazards but also to unveil the spectrum in the evolution of the magnificent Himalayan mountain chain. One of the most striking aspects of the Himalayan orogeny is the lateral continuity of its major tectonic elements namely The Shivaliks, The Lesser Himalayas, The Higher Himalayas and The Indus Suture Zone. Thus, in this context analysis of earthquakes using modern methods has been taken into account in which Seisan software and HypoDD for location of earthquakes has been incorporated. The method used here for location of earthquake hypocenters is a double-difference algorithm known as hypoDD, which solves for event hypocenters and origin times using differential travel-time data from catalogue phase picks and waveform cross correlations. In the present study, one year data of nine stations situated in the North-Western Himalaya for the year 2017 has been used.
