The USGS Earth Explorer program shared these before-and-after pictures of Puerto Rico. The main difference that’s visible from the Landsat 8 satellite after hurricanes Irma and Maria blasted through is in the vegetation. Lots of trees denuded of leaves or just plain knocked over – which means the patches of green visible from space in 2016 are more brown, after September 2017. I can’t tell if the patchiness on the lower right is all clouds or if some of that is sediment stirred up by the storm – the USGS has some other images of the Keys after Irma that have some similar cloudiness off the beaches.
But they’ll grow back. Eventually.
