The Ganga and Yamuna rivers emerge from the Himalayas along two major faults known as the Ganga and Yamuna Tear faults, respectively. The two major gliding faults transverse to the Siwalik area are clearly seen in the satellite images of the Dehradun area. Recordings of earthquakes, landslides, and recent changes in geomorphological characteristics indicate that the area between the thrust of the main limit and the main frontal thrust is tectonically active. An effort has been made to study the tectonic evolution and neotectonism of the lacrimal faults of Ganga and Yamuna. Spectral and spatial enhancement techniques have been employed for the digital data of the IRS-1B LISS-I to delineate the guidelines and major area failures. Based on Mohr's theory, failure criteria and the statistical analysis of the data of the teledetected lines, the values of horizontal compressive stress (SHmax) have been estimated at several sites in the study area. These data were found to be consistent with published SHmax orientation determined from quake focal mechanism solutions. The active faults and the guidelines have been extracted from the data of the teledetectado guidelines. Data from previous earthquakes and depth of basement contour data have been used in an integrated approach with available Geographic Information System (GIS) techniques to reconstruct a current regional geodynamic model. Attempts have been made to investigate the genesis of the Ganga and Yamuna Tear faults and the possible causes of the recent tectonic activities of the area with the help of the proposed geodynamic model.
