An Indian seismologist says more than 70 aftershocks have been recorded in the Himalayan region since Saturday's earthquake. J.L. Gautam says the 73 aftershocks recorded as of Thursday morning by India's monitoring stations ranged from 3.2 magnitude to 6.9, the strongest occurring on Sunday. Gautam is the director of seismology at the Indian Meteorological Department in New Delhi. India monitors seismic activity from stations in the Himalayan foothills in northern India in the towns of Gangtok, Dehradun and Shimla and others in Shillong and Guwahati in northeastern India. Gautam said the aftershocks will continue for "a few weeks, or months, or even years." He says, "These aftershocks are quite normal after a powerful earthquake of such magnitude." http://english.ahram.org.eg/News/129046.aspx
