摘要

Earthquake records, landslide and recent changes in geomorphological features indicate that area between Main Boundary Thrust (MBT) and Main Frontal Thrust (MFT) is tectonically active. Spectral and spatial enhancement techniques have been employed for the digital data of IRS-1B LISS-I to delineate the lineaments and major faults of the area. Based on Mohr's theory failure criteria and statistical analysis of remotely sensed lineament data, the horizontal compressive stress (S-Hmax) has been estimated at various sites of the study area. These data are found to be consistent with the published S-Hmax orientation determined from earthquake focal mechanism solution. [References: 6]
