This is one of the best presentations I have yet seen on the destruction encountered in Japan. They are satellite photos taken before and after of various areas, but what makes them especially descriptive is the method of presentation. As you move the mouse slowly over the picture, from right to left, the 'before' sat photo is replaced by the 'after' sat photo, giving you an immediate comparison. (Not click and drag, just move the mouse)
The before & after really bring home the extent of property damage.
