Development of Probabilistic Seismic Hazard Assessment for North Western Mountainous Region, Himachal Pradesh

Abstract

The Himalayan Mountain range is one of the most significant tectonic structures thought to have been created by the collision of two continents as a result of the relative movement of plates (Dewey and Bird, 1970). The Western Himalayas, also known as the Northwest (NW) Himalaya, is located between the latitudes of 30-33 degrees North and the longitudes of 75-78 degrees East. This area is seismically active and is classified as belonging to seismic zones IV and V on the India hazard zonation map. The Indian plate is still moving to the north, which is creating a lot of tension at the plate boundary that is being released in the form of massive and powerful earthquakes. There should be a focused study on seismic hazard assessment since growth connected to building is growing. This study presents comprehensive research on probabilistic seismic hazard analysis for mountainous regions.
