These false-color images taken by NASA’s Terra satellite show the city of Ishinomaki, northern Japan on August 8, 2008 (top) and March 14, 2011. Ishinomaki is one of several coastal cities brutalized by the swirling wall of waves from the tsunami caused by the earthquake that devastated northern Japan on March 11. Water is dark blue in this false-color image. Plant-covered land is red, exposed earth is tan, and the city is silver.
Croplands and settlements lining the Kitakami River in Miyagi Prefecture are seen on Jan. 16, 2011 (top) and then on March 14, 2011 (bottom) showing ocean waters flooding croplands and settlements following the magnitude 9.0 earthquake and tsunami that struck the region in this combination satellite photo provided by NASA.
This NASA photo taken from 220 miles above Japan by an Expedition 26 crew member onboard the International Space Station shows the earthquake and tsunami damaged city of Sendai on March 13.
Coastal flooding from the March 11 tsunami triggered by a magnitude 9.0 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, in this image released by NASA, March 14.
Damage is shown to the Fukushima Dai-ichi nuclear facility in Japan on March 14. Authorities are struggling to prevent the catastrophic release of radiation in the area devastated by a tsunami. DigitalGlobe/AP

This image provided by the Pacific Tsunami Warning Center shows a 'tsunami forecast model' created by the Pacific Tsunami Warning Center in Ewa Beach, Hawaii predicting the wave height of the tsunami generated by the Japanese earthquake on March 11. Hawaii's islands are located at the edge of the yellow pattern, but waves could be higher along the coastline when the tsunami arrives.
The tsunami of Decemebr 26, 2004, struck hardest along the northwest coast of Sumatra, in Indonesia's Aceh province. The water was channeled inland through low-lying areas, such as stream floodplains. This image of Gleebruk, a small town located roughly 31 miles from Banda Aceh, shows the degree of destruction.
On December 26, 2004, a large (magnitude 9.0) earthquake occurred off the western coast of Sumatra in the Indian Ocean. The earthquake was caused by the release of stresses accumulated as the Burma tectonic plate overrides the India tectonic plate. Movement of the seafloor due to the earthquake generated a tsunami, or seismic sea wave, that affected coastal regions around the Indian Ocean.
The Indonesian province of Aceh was hit hardest by the earthquake and tsunamis of December 26, 2004. Aceh is located on the northern tip of the island of Sumatra. Early Western media attention was focused on Sri Lanka and Thailand, even though the earthquake epicenter was closer to Aceh, and the largest waves struck the northwestern coast of Sumatra.
Satellites continue to acquire imagery of areas severely damaged by the tsunami of December 26, 2004. This image of Meulaboh, Indonesia, was collected on January 7, 2005, by DigitalGlobe's QuickBird satellite.
The Indian Ocean coastline north of Phuket, Thailand is a major tourist destination that was in the path of the tsunami produced by a giant offshore earthquake on December 26, 2004.
On May 19, 2004, a tropical cyclone moved ashore over northern Myanmar bringing strong tidal surges and coastal flooding.
The tsunami of Dec. 26, 2004, struck hardest along the northwest coast of Sumatra, in Indonesia's Aceh province. The water was channeled inland through low-lying areas, such as stream floodplains. These images of Gleebruk, a small town located roughly 31 miles from Banda Aceh, show the degree of destruction.
This series of images shows tsunami damage in the Aceh province of northern Sumatra. Located immediately west of the epicenter of the earthquake that triggered the tsunami, this region was both the first to be impacted by the massive wave and the most severely damaged.
This DigitalGlobe satellite image, released on Dec. 30, 2004 shows the shoreline area of Banda Aceh on northern Sumatra in Indonesia, before and after the devastating tsunami that struck Asia.
This combination of satellite images received from DigitalGlobe in 2004 shows the before image (top) taken 23 June 2004 and the image taken on 28 December 2004 with the floaded aeras and destroyed buildings of Banda Aceh city, after a tsunami hit the area.
The Sri Lankan coastline was devastated by the tsunami which was triggered by a massive 9.0 earthquake of the Indonesian island of Sumatra across the Indian Ocean in Dec. 2004.
The image of Aceh on northern Sumatra on the left was taken on January 10, 2004 while the image at right was taken December 29, 2004.
