Before and After Image of Northeastern Japan after Tsunami Hit

Coastal flooding from the March 11, 2011 tsunami triggered by a magnitude 8.9 earthquake off Japan's northeast coast can be seen in this before/after image pair from the Multi-angle Imaging SpectroRadiometer (MISR) instrument on NASA's Terra spacecraft.

NASA’s Multi-angle Imaging SpectroRadiometer (MISR) instrument onboard its Terra satellite was able to provide before and after images of the extent of the coastal inundation along the northeastern coast about 130 kilometers (82 miles) east of the city of Sendai.

The original image was taken 10 years ago on March 16, 2001, under nearly identical illumination conditions. The new image, on the right, was taken on 10:30 am local time, or 01:30 UST) on March 12, 2011, and shows the flooding extend more than 4 kilometers, or 2.5 miles inland from the eastern shoreline.
