چکیده انگلیسی
We used high-resolution satellite (CARTOSAT-1) data for mapping active fault traces and carried out paleoseismic studies to identify paleo-earthquakes along the HFT. A trench excavated across the Kaladungi Fault (KF), a branching fault of HFT, revealed evidence of at least three earthquakes. Event I (the oldest) occurred between BCE 467 and CE 570; Event II occurred between CE 1294-1587. We infer that the Event II was the most likely historically-reported, great Himalayan earthquake of CE 1505. Event III occurred between CE 1750-1932, and may represent the large magnitude CE 1803 (7.5 > Mw < 8.0) earthquake. Our findings not only help in understanding the frontal fault dynamics, but also may aid seismic hazard evaluation in India and Nepal.
