Mapping Japan’s changed landscape from space

Following the massive earthquake and tsunami that hit Japan on March 11th, satellite imagery has been key in providing a clear picture of the extent of devastation to aid the relief effort now underway.

In response to this event, which turned out to be the biggest earthquake Japan has suffered in living memory, the International Charter ‘Space and Major Disasters’ was triggered by the Cabinet Office of Japan the day the earthquake struck. As a result, satellite images from several space agencies and operators from around the world are being used to map and assess the stricken areas in Japan. The satellites are providing essential information for search and rescue teams on the ground and for damage assessment in the recovery process. Before-and-after images show how the land has changed and where buildings and roads once stood. Over 63 satellite acquisitions were made in the first 48 hours following the earthquake. These are being used by relief teams and decision-makers responding to the disaster.
