20.Įarlier images released by the European Space Agency showed a bird's-eye view of Maria's destruction of the power grid. 25, less than a week after the storm made landfall on Sept. The before image was captured on July 24, and the after image was taken on Sept. The GIF above shows a bird's eye view of Puerto Rico before and after Maria devastated its power grid. It can also detect light from fires, lightning, reflected moonlight and emissions from cities. The images are based on data from the Visible Infrared Imaging Radiometer Suite (VIIRS) “day-night band,” which spots light in various wavelengths such as green to near-infrared, according to NASA.

NASA collected the images to help first responders pinpoint where power is out so that they can act accordingly.
29, they show a dramatic decrease in lights from human activity due to the widespread outages. The before-and-after images show regions within the territory that are still without power in comparison to regular nights before the storm hit. More than a week after Hurricane Maria devastated Puerto Rico, much of the island’s power grid remains offline, and recently released NASA satellite images show the extent of the outages.
