Continuous Monitoring Permanent GPS Station at Imphal for Crustal Deformation and Earthquake Studies

The north eastern part of the Indian subcontinent is one of the most seismically active regions of the world and displays a complex geodynamic situation. It consists of Eastern Himalayan Mobile belt, Mishmi Block, Indo-Myanmar Mobile Belt, Meghalaya Plateau, Mikir Hills and Brahmaputra Valley. The plate motion and geodynamic processes are poorly understood due to the complex geodynamic setting of the region. In order to understand the earthquake occurrence process and assess the future seismic hazards in this region different permanent GPS station has been established. A brief description of one of the GPS permanent station i, e, IMPH in the Indo-Myanmar wedge (IMW), data processing, analysis during the 2004 Sumatra Andaman earthquake (M 9.2) and Manipur earthquake (M 6.7) as a case studies are presented in this paper.
