Scientists are using satellite data to map changes in the earth’s surface as a result of the recent explosion.
NASA’s Advanced Rapid Imaging and Analysis (ARIA) team, in collaboration with the Earth Observatory in Singapore, used satellite radar data from synthetic apertures to map the likely extent of the August 4 massive explosion in Beirut. Radar data from the synthetic aperture from space show changes in the earth’s surface before and after a major event such as an earthquake. In this case, it is used to show the disastrous result of an explosion.
On the map, dark red pixels – such as those in and around the port of Beirut – represent the worst damage. The areas in orange are moderately damaged, and the areas in yellow probably suffered a little less damage. Each color pixel represents an area of 30 meters (33 yards).
Maps like this can help you identify severely damaged areas where people may need help. The blast occurred near the city̵
The map contains modified data from Copernicus Sentinel, processed by ESA (European Space Agency) and analyzed by scientists from the ARIA team at NASA JPL, Caltech and the Singapore Earth Observatory. Located in Pasadena, California, Caltech manages the JPL for NASA.
