Great East Japan Earthquake
Tsunami Amplified by Land Subsidence
(NASA satellite image)
A swath of agricultural fields lies between the Japanese city of Sendai and Sendai Bay, and the area was one of the hardest hit by the tsunami on March 11, 2011, The Advanced Land Imager on NASA's Earth Observing-1 satellite captured this natural-color image of the area on March 18, 2011.
One week after the magnitude-9.0 earthquake and resulting tsunami, the fields nearest the ocean were still covered with standing water. It is possible that some areas could remain that way, as the ground level sank along the east coast of Japan during the earthquake. The same tectonic forces that lifted up the seafloor to create the tsunami also caused land to subside on the mainland. Liquefaction of soil and sediments may also have caused settling.
