Japan (earthquake risk)
The tsunami-spawning, magnitude-9 earthquake that hit Japan on 11 March was the largest tremor to strike the region in hundreds of years, but immense amounts of seismic stress remain stored in the area’s tectonic interfaces — and the next large quake could occur much closer to Tokyo, a troubling analysis suggests. $$$
Seismology
New Work Reinforces Megaquake’s Harsh Lessons in Geo-science. High-tech analyses of Japan’s March earthquake overturn long-held views of fault behavior and warn that another disaster may be looming. The moment the Tohoku-Oki earthquake struck off northern Japan on 11 March, many researchers knew their expectations had been shattered. The great offshore fault could not be counted on to behave at all predictably. And using onshore observations to gauge whether an offshore fault is building toward failure has grave limitations. $$$
Seismology
Seismic Crystal Ball Proving Mostly Cloudy Around the World. Failing at quake prediction, seismologists tried making fuzzier forecasts, but Japan’s mega-quake is only the latest reminder of the method’s shortcomings. When a devastating mega-quake rocked the region north of Tokyo in March, nobody saw such a huge quake coming. “Japanese scientists are among the world’s best, and they have the best monitoring networks,” notes geophysicist Ross Stein of the U.S. Geological Survey (USGS) in Menlo Park, California. “It’s hard to imagine others are going to do forecasting better. No one group is doing it in a way we’d all be satisfied with.” $$$
United States (Nuclear stress tests)
Federal regulators say the San Onofre nuclear generating station on the Southern California coast is at extremely low risk of a meltdown in an earthquake. The Nuclear Regulatory Commission says inspections this year found a few problems at the plant between Los Angeles and San Diego but concluded it is able to cope with the threats of fire and flooding. $$$
New Zealand (Christchurch)
Rise Up Christchurch is a chance to show younger generations how Kiwis can unite together, event organizer Brooke Howard-Smith says. From 9am to 9pm this Sunday, the Rise Up Christchurch Global Telethon will aim to raise as much money as possible for the Christchurch Earthquake Appeal. $$$
United States (USGS)
The U.S. Geological Survey’s (USGS) Prompt Assessment of Global Earthquakes for Response (PAGER) system, operational since mid 2007, rapidly estimates the most affected locations and the population exposure at different levels of shaking intensities. The PAGER system has significantly improved the way aid agencies determine the scale of response needed in the aftermath of an earthquake. $$$
Earthquake-Report.com remark : USGS Pager is also used (among other similar tools) to enrich our own articles with quick disaster data.
Pacific Ocean (tsunami preparedness)
The Intergovernmental Coordination Group for the Pacific Tsunami Warning and Mitigation System (ICG/PTWS) will organize a Pacific-wide tsunami exercise in November to test the preparedness and performance of more than 30 Pacific countries. The exercise, dubbed PacWave 11, aims to test the countries’ tsunami warning systems as well as their disaster prevention and mitigation systems, ICG/PTWS Chairman Giorgio de la Torre said here at the organization’s 24th session Tuesday. $$$
QuakeSOS+ and QuakeSOS free are iPhone applications developed by Armand Vervaeck, the founder of Earthquake Report. The Application simplifies immediate group communication to friends and family members (with your exact GPS location) and is feeding the users with Earthquake Report news. The 0.99 US$ QuakeSOS+ version will support the activities of SOS Earthquakes.
