InSAR: Tracking Natural Disasters Through Technology

Innovation Now


Researchers supported by nasr's applied sciences disasters program us satellites and space to gauge damage that natural hazards such as hurricanes and earthquakes. 'cause on earth one such satellite-based technology is called interferon metric synthetic aperture radar or in sar in sar can reveal surface movements down to a few millimeters even across an area hundreds of kilometers wide sang. Ho yun a geophysicist at nasa jet propulsion laboratory notes that the technology brings other advantages. Sar doesn't need daylight. We can see things ban night. Also we can see through clouds. We can see through rain. We can see through wildfire smoke and we can see through volcanic plume and other researchers at nasa us inside data to create maps. That show likely damage to buildings and infrastructure in the wake of disasters. The maps help responders and relief workers make better informed decisions and speed recovery
