NASA advanced snapshot satellite map Damage from the explosion: Aftermath of the Beirut explosion



NASA's Beirut explosion damage

NASA’s ARIA team, in collaboration with Singapore’s Earth Observatory, used satellite data to map the extent of the damage that could have occurred after a major explosion in Beirut. Dark red pixels represent the most severe damage. Orange areas are moderately damaged and yellow areas may be less damaged. Each color pixel represents an area of ​​30 meters (33 yards). The map containing Copernicus Sentinel data has been modified by ESA (European Space Agency) and analyzed by ARIA team scientists at NASA’s Jet Propulsion Laboratory, Caltech, and Observatory close to the Earth of Singapore. Based in Pasadena, California, Caltech manages the JPL for NASA.

Scientists are using satellite data to map changes in the ground surface as a result of the recent explosion.

NASASingapore’s Advanced Rapid Imaging and Analysis (ARIA) team, in collaboration with Singapore’s Earth Observatory, used the combined aperture radar data obtained from the satellite to map the extent of damage. could have happened from the big explosion on August 4 in Beirut. Composed aperture radar data from space shows changes in the ground surface before and after a major event such as an earthquake. In this case, it is being used to display the dire results of an explosion.

On the map, dark red pixels – like the existing ones in and around the Port of Beirut – represent the heaviest damage. Orange areas are moderately damaged and yellow areas may be less damaged. Each color pixel represents an area of ​​30 meters (33 yards).

Maps like these can help identify severely damaged areas for which people may need assistance. The explosion occurred near the city’s port. It has claimed the lives of more than 150 people and is estimated to have caused damage worth billions of dollars.
