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.

Norihiro Sakamoto, the former head of technology at the Society of Japanese Aerospace Companies, currently serves as a researcher for the Tokyo Foundation and has been advocating development of a "real-time warning system" for tsunami.

To prepare for a disaster when communication networks and satellite dishes are forced offline because of tsunami-related damage, an idea has been floated of building an "ultra-large deployable satellite... read more

Faster tsunami warnings could be issued by using Global Positioning System (GPS) data alongside existing earthquake detection technology, scientists have found. GPS data — provided by a satellite navigation system — could help cut the time lag from 20 minutes to around three minutes, according to results presented at the American Geophysical Union meeting in the United States, last week (8 December).

Seismic instruments — on which current warning systems are based — can take a long time accurately to assess an earthquake's strength, because readings from several locations need to be analysed. However, GPS... read more

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.

Data from NASA and European radar satellites captured at least two wave fronts that day. The fronts merged to form a single, double-high wave far out at sea. This wave was capable of traveling long distances without losing power. Ocean ridges and undersea mountain chains pushed the waves together along certain directions from the tsunami's origin.

The discovery helps explain how tsunamis can cross ocean basins to cause massive destruction at some locations while leaving others unscathed. The data raise hope that scientists may be able to improve tsunami forecasts.

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 Earth Observation Systems (EOS), we will assess the damage to the area impacted by this disaster. Landsat 5 Thematic Mapper (TM), MODIS on Aqua and Terra, and ASTER will be used to create normalized difference vegetation indices (NDVIs) and land classifications of the area. MODIS also will be used to measure sea surface temperature to assess the feasibility of using... read more

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.
DAICHI, launched on January 24, 2006 (JST), had been operated for over five years, which was its target life and well beyond its design life of three years, and it achieved many fruitful results related to earth observations.
We would like to express our profound appreciation to all pertinent organizations and personnel for their cooperation with our DAICHI operations. JAXA continues to investigate the... read more

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.

The process of loss assessment, clean-up and rebuilding has begun. One month after the original 9.0 magnitude event, 408 aftershocks greater than 5.0 intensity had occurred and are expected to continue for as long as ten years. Progress, albeit slow at first, is stalled or even reversed with each new tremor.

Damage to their nuclear power facilities may have an impact on the ocean and... read more

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.

Scientists from Italy’s Istituto Nazionale di Geofisica e Vulcanologia have used the same Envisat data to show a large portion of the surface displacement, with a maximum shift of 2.5 m. These first results, covering an 800 km-long strip over Sendai and Tokyo, show movement far away from the epicentre (denoted by the red star in the top image) in the Pacific Ocean.

The complex technique being used by the scientists is known as ‘InSAR’ – synthetic aperture... read more

The massive earthquake and tsunami that devastated northeast Japan recently has given rise to a new phenomenon called a complex mega-disaster . Such a catastrophe takes place only when a massive earthquake occurs underneath an ocean, large enough to create movements on the sea floor.

A recent geological analysis of terrestrial as well as extra-terrestrial satellite data has the potential to predict earthquake and tsunami in space and time. It has been observed that before the occurrence of this combination the temperature of earth, sea surface and... read more
