In the days following the Japanese earthquake and tsunami, we showed you a great tool from ABC news that used Google Earth imagery with a slider to flip back and forth between pre and post-earthquake imagery.
Now we’ve been shown a similar tool for showing damage from the tornadoes that hit Tuscaloosa, and it’s just as impressive and heart-breaking as the Japanese imagery.
To try it for yourself, simply head over to this page on the Tuscaloosa News site. Use the blue buttons on the right side to select an area to view, and slide the white bar from side-to-side to view the difference in the imagery.
