Science Daily Thursday 7th April, 2011
ScienceDaily (Apr. 7, 2011) -; Researchers at the Institute of Geomatics -- Research Centre of the Polytechnic University of Catalonia (UPC) and the Government of Catalonia -- have estimated the ground deformation suffered in the area of Sendai, Japan, as a consequence of the earthquake of 11 March and its aftershocks. The estimate was derived from 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.
