The nation's ability to detect and forecast tsunamis has improved since the 2004 Indian Ocean tsunami, but current efforts are still not sufficient to meet challenges posed by tsunamis generated near land that leave little time for warning, says a new congressionally requested report from the National Research Council. The report calls for a comprehensive national assessment of tsunami risk and improved communication and coordination among the two federal Tsunami Warning Centers, emergency...

Australian researchers describe a mathematical model in the International Journal of Operational Research that can find the ten optimal sites at which tsunami detection buoys and sea-level monitors should be installed. The model could save time and money in the installation of a detection system as well as providing warning for the maximum number of people should a potentially devastating tsunami occur again in the Indian Ocean. A magnitude 9.3 shook the sea floor off the coast of Aceh, in...

The first tsunami hit Japan's outlying islands early Sunday after a strong earthquake rocked the South American country of Chile on Saturday morning. Japan's Meteorological Agency said the first wave was recorded in the Ogasawara islands.  It was only 4 inches high.  Another wave was seen in Hokkaido that was 12 inches high. The Pacific Tsunami Warning Center has already lifted its warning for every country but Russia and Japan.  Some countries, including the Philippines,...

LOS ANGELES, Feb. 27 /PRNewswire-USNewswire/ --International Medical Corps is monitoring the situation in Chile and in areas in the Pacific basin where tsunami warnings have been issued, following an 8.8-magnitude earthquake that struck early Saturday. Emergency Response Teams are preparing to deploy to Chile and potential tsunami areas, and are gathering the necessary medicines and supplies. The quake struck at 3:34 a.m. local time and was centered about 70 miles from Concepcion,...

Experts say American Samoa was the victim of a perfect storm during the recent tsunami that has resulted in a death toll of 150 people and rising. The region was subject to a massive magnitude 8.0 earthquake that triggered strong winds and enormous ocean waves. Because it occurred in the ocean floor beneath deep water, the waves were larger and it quickly gained more speed and power. "Put that all together and there was less than 25 minutes, maybe as little as 13 minutes, between the ground...

U.S. government researchers announced Wednesday that satellites can spot the leading edge of a Tsunami by detecting giant waves and getting people out of their way. The researchers looked at satellite images in the Indian Ocean as the December 2004 tsunami hit Thailand, Sri Lanka and other places.  They found patterns in the water that shows evidence of the big wave. "We've found that roughness of the surface water provides a good measure of the true strength of the tsunami along its...

Scientists reported that a powerful earthquake off Russia's eastern coast on Monday caused automated monitoring systems to falsely indicate small temblors in Idaho and California. The U.S. Geological Survey said the real quake had a preliminary magnitude of 7.3 and struck the Sea of Okhotsk 195 miles west of Petropavlovsk-Kamchatskiy, on Russia's Kamchatka Peninsula.  In the western U.S., the jolt caused computerized seismic stations to send out false quake reports.  The report...

The newly implemented Tsunami Early Warning System for the Indian Ocean, GITEWS, goes into operation today and with this, the system enters its final phase of optimization. As foreseen, the system was officially handed over to the BMKG (Meteorological, Climatology and Geophysical Agency of Indonesia) by the President of Indonesia, Susilo Bambang Yudhoyono, in the Indonesian capital Jakarta, slightly less than four years after the catastrophe of 2004. "We are very pleased to put the Tsunami...

For humans in the path of destructive hurricanes and tsunamis, an accurate warning of the pending event is critical for damage control and survival. Such warnings, however, require a solid base of scientific observations, and a new satellite is ready for the job. The Ocean Surface Topography Mission (OSTM)/Jason 2 adds to the number of eyes in the sky measuring sea surface and wave heights across Earth's oceans. The increased coverage will help researchers improve current models for...

PITTSBURGH -- Researchers are hoping to develop a network of ocean-floor and mobile sensors that would help detect tsunamis in the Indian and Pacific oceans. The low-cost devices would complement existing deep-water tsunami-detection buoys, providing measurements and analysis of seismic movements more quickly and accurately than the buoys alone, said Louise Comfort, a University of Pittsburgh professor working on the project. They would offer greater coverage of the oceans by filling in large...
