Researchers have estimated the ground deformation suffered in the area of Sendai, Japan, as a consequence of the earthquake of March 11 and its aftershocks, based on radar observations acquired by the Envisat satellite of the European Space Agency. According to this estimate, obtained over an area of approximately 300 x 100 km around the city of Sendai, the terrain has suffered a co-seismic deformation -- permanent deformation of Earth's surface -- associated with the earthquake of up to 1.69 m.
