ISRO-NASA satellite NISAR to map Himalayas’ seismic zones
The HinduA forthcoming satellite, NISAR, jointly developed by the Indian Space Research Organisation and the National Aeronautics and Space Administration of the U.S. will map the most earthquake-prone regions in the Himalayas with unprecedented regularity. The NISAR satellite, expected to cost approximately $900 million will use two frequency bands: the L-band and S-band to image the seismically active Himalayan region that will, every 12 days, create a “deformation map”, said Prakash Chauhan, Director, ISRO-National Remote Sensing Centre at a seminar here this week. “ These many stations are still too few and there’s only one satellite that we rely on…with NISAR, the costliest space mission ever, we can have a game-changer in earth-science observation,” said Dr. Chauhan. “With a frequency of 12 days and the ability to be able to provide images even under cloudy conditions, NISAR would be a valuable tool to study deformation patterns, such as in Joshimath,” he added.
