On Tuesday, there was a serious explosion in the port area of Beirut, Lebanon. The dangerous chemicals stored for many years were accidentally detonated, with preliminary estimates of 150 deaths and thousands of injuries. Nasa has shared a satellite photo of August 4 to give a more intuitive picture of the extent of the damage caused by the blast. It is reported that the image uses synthetic aperture radar data on the satellite.
In collaboration with the Singapore Earth Observatory and Caltech’s Jet Dynamics Laboratory, NASA’s Advanced Rapid Imaging Analysis (ARIA) team shared this satellite image on Friday, with the actual edge length of each pixel at about 30 meters.
The yellow and red colors on the image indicate the different depths of the explosion. The area closest to the port shows the heaviest dark red. The orange pixelindicates moderate damage and the yellow pixel indicates a slight erst.
NASA says it hopes the image will help local rescue arrangements.
