NASA and Ohio State University researchers have discovered the major tsunami generated by the March 2011 Tohoku-Oki quake centered off northeastern Japan was a long-hypothesized "merging tsunami." The tsunami doubled in intensity over rugged ocean ridges, amplifying its destructive power at landfall.
On March 11, 2011, the Great Tohoku Earthquake occurred approximately 70 kilometers off the coast of Japan. This magnitude 9.0 earthquake was closely followed by a massive tsunami that reached 7 meters in height. Using NASA
The Japan Aerospace Exploration Agency (JAXA) had been trying to communicate with the Advanced Land Observing Satellite "DAICHI" (ALOS) for about three weeks after it developed a power generation anomaly; however, we decided to complete its operations by sending a command* at 10:50 a.m. on May 12 (Japan Standard Time) as we found it was impossible to recover communication with the satellite.
Japan’s space budget will take a hit as resources are diverted to recovery efforts following the March 11 earthquake and tsunami, but the Japanese government is determined to maintain most space investment efforts, a top Japanese official said April 13.
GeoEye has been supporting the relief efforts by providing its satellite imagery of the devastation in northern Japan to relief agencies, governments and the media. On March 11, 2011, GeoEye's order management team began directing the high-resolution satellites to collect color imagery over the Oshika Peninsula. IKONOS captured the first post-earthquake image at 10:36 a.m. local time.
Satellite images have been essential for helping relief efforts in Japan following the massive quake that struck on 11 March. Now scientists are using ESA’s space radars to improve our understanding of tectonic events.
The Emirates Institution for Advanced Science & Technology (EIAST), the UAE’s premier scientific and technology organisation, has provided recent images of Japan from its UAE-owned and operated DubaiSat-1 satellite. The images of the tsunami and earthquake struck cities were provided to the United Nations Platform for
Japan needs maps. Not just any kind—detailed informational maps georegistered with latitude and longitude and annotated with simple, self-evident details: this bridge is out, this port is damaged, this farm field is scoured; this one is verdant.
