Here are some Tsunami pictures capture by satellite that show before and after images of the regions affected by the tsunami.

This photograph shows the devastation that happened in Sri Lanka on December 26th. This picture was taken by the DigitalGlobe Quickbird satellite, and shows how the whole coastline was inundated with water.

This photograph, captured by NASA’s Terra satellite shows how the whole northwest coast of the island of Sumatra was hit hard by the tsunami. It looks like the vegetation was just scraped back from the edge of the island.

We have written many articles about the devastation from the 2004 tsunami. Here’s an article about how GPS could be used for a tsunami warning system.

You can get many more tsunami pictures from NASA from their Earth observation page.
