Expert proposes better use of satellites for disaster management

Japan: Norihiro Sakamoto proposed a plan to make better use of existing satellites so that they could make quicker tsunami forecasts. This would involve using a quasi-zenith satellite system, whereby a satellite is always located near Japan's zenith, so that there is a continuous link with offshore tsunami observation devices.

NASA: Two Waves Formed Japan's Destructive Tsunami

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.

DAICHI (ALOS) Operation Completion

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.

TeraGrid: Paying it forward in the wake of disaster

While reports vary, some estimate the total cost of Japan's March 11, 2011 earthquake and tsunami at 25 trillion yen, or 330 billion U.S. dollars, making it the most costly natural disaster on record. This is more than three times the size of the second most expensive natural disaster, also an earthquake, and also in Japan in 1995. More than 26,000 are dead or missing and an estimated 400,000 are homeless. Nearly a quarter of Japan's total geography has been altered.

Response To Japan's Disaster Relief Efforts

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.
