.This satellite image is from the DigitalGlobe Flickr Photostream, and was collected mid-morning on March 16th local time. Four reactors are shown with #1 on the right. #1 had a hydrogen explosion early in the disaster, which removed the upper-floor walls and roof. #3 had a very large hydrogen explosion, and is emitting the most steam. It is the only reactor that contains a special plutonium mixture called MOX. #4 on the left had been shut down before the earthquake occurred, and had no fuel in the reactor, but contained a spent fuel pool on one of the upper floors, which had a hydrogen explosion and caught fire. #2 had a hydrogen explosion in the pressure suppression toroid beneath the reactor, which is releasing a large amount of radiation.
