NISAR Satellite

Source: TH

 Context: India’s ISRO and NASA are jointly developing a satellite called NISAR that will map the most earthquake-prone regions in the Himalayas with unprecedented regularity.

 

How NISAR will map Himalayas’ seismic zones?

The satellite will use two frequency bands to image the seismically active Himalayan region and every 12 days, create a “deformation map” to give advance warning of land subsidence and places that are at greatest risk from earthquakes.
