The aftermath of the catastrophic quake and tsunami in Japan has mobilised unprecedented participation from social networks and crowd sourcing communities around the world. Satellite imagery released for free by major commercial satellite companies earlier this week revealed to the world the extent of the impact of the tsunami waves that hit the east coast of Japan on Friday 11 March. Japan is using various satellite sensors and is coping with the technical work necessary to turn this large amount of data into useful information for rescue and rehabilitation operations.
