It's almost impossible to grasp the scale of the tsunami that slammed into Japan yesterday following the 8.9-magnitude earthquake that struck off the coast near Sendai. The quake was a global-scale event, shifting the axis of the entire earth by four inches.

If you click on the photos, you can see the very high-resolution photos that NASA's Terra Satellite captured.
