Abstract
The epicentre of the destructive 20 October 1991 earthquake is in the north‐east of the Uttarkashi region of the Higher Himalaya. The earthquake was felt up to 250–350 km away from Poh and Keylong in the north to Delhi in the south and beyond Chandigarh in the west. Seismologists of the Seismotectonic Group of Wadia Institute of Himalayan Geology studied fissures, surface breaks, and the foreshock and aftershock activity caused by this event. Land fissures show normal dislocations of 0.06–1 m, run E‐W and NE‐SW in the epicentral region and could be followed for 30–40 km.Keywords
