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.
In the wake of the devastating earthquake and tsunami, Japan is investing in sensors and systems to ensure resilience. The country looks for more real-time feedbacks, and better predictive models, in order to better prepare and reduce impacts from future disasters.
The Japanese government will host a ministerial-level international conference on natural disasters in early July in the three prefectures hit hardest by the March 11 earthquake and tsunami, according to Foreign Ministry officials. The conference is an opportunity for other countries to share lessons from and responses to disasters. The government also hopes to use the conference to showcase restoration and
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.
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.
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.
