Seismotectonic Study of the Indo-Gangetic Plain Using Distribution and Direction Analysis

Indo-Gangetic Plain (IGP) is vulnerable and prone to seismic hazards due to intricate networks of rivers, proximity to the Himalayas, and high density of inhabitants. The present study aims to evaluate seismicity for the IGP through geospatial analysis. The geospatial analysis includes fault frequency-length density analysis and fault orientation analysis for earthquake epicenters and faults. This study recognized the IGP as a high-strain region based on the cumulative distribution of faults which follows the exponential law. Fault frequency-length density analysis indicates that the Himalayan Mountain range (HMR) and the region between the Aravalli Mountain range (AMR) and the great boundary fault (GBF) hold a high level of density.
