Satellite Photos of Japan, Before and After the Quake and Tsunami
Compare satellite images of areas of Japan before and after the disaster.
The sudden movement of the Pacific tectonic plate under the North American plate caused a massive earthquake and a tsunami.
An 8.9-magnitude earthquake struck the coast of Japan on Friday at a depth of about 17 miles below the earth's surface. Dozens of aftershocks, some of magnitude 6.0 or greater, were felt after the quake.
The tsunami set off warnings for much of the Pacific basin including the west coast of the United States and South America. Officials say waves have not caused major damage in Hawaii and pose no flooding danger in California.
