Scientists seek to create reliable early warning systems that accurately estimate the magnitude of an earthquake within the first seconds of rupture. In this paper published by the Bulletin of the Seismological Society of America, authors S. Murphy of University College Dublin, Ireland and S. Nielsen of the Instituto Nazionale di Geofisica e Vulcanologia, Roma, Italy look at the idea that an earthquake's final size can be determined during its initiation, rather than something that only becomes apparent at the end of the rupture. http://www.physorg.com/news152375731.html Space & Earth Wed, 28 Jan 2009 14:35:53 EST news152375731 A University of Colorado at Boulder professor says the powerful earthquake that knocked down buildings and killed at least 130 people in and around the medieval city of L'Aquila in Italy April 6 is a continuation of violent seismic events that have periodically rocked the region dating back to Roman times. http://www.physorg.com/news158261104.html Space & Earth Mon, 06 Apr 2009 18:25:50 EST news158261104 The May 12 earthquake that rocked Sichuan Province in China was the first there in recorded history and unexpected in its magnitude. Now a team of geoscientists is looking at the potential for future earthquakes due to earthquake-induced changes in stress. http://www.physorg.com/news134575404.html Space & Earth Sun, 06 Jul 2008 15:03:24 EST news134575404 A new study evaluates expected ground motion in Seattle, Victoria and Vancouver from earthquakes of magnitude 7.5 - 9.0, providing engineers and policymakers with a new tool to build or retrofit structures to withstand seismic waves from large "subduction" earthquakes off the continent's west coast. http://www.physorg.com/news163905800.html Space & Earth Thu, 11 Jun 2009 02:23:30 EST news163905800 A magnitude 8.0. earthquake destroyed 90 percent of the city of Pisco, Peru on August 16, 2007. The event killed 595 people, while another 318 were missing. Tsunami waves were observed locally, off the shore of Chile, and as far away as New Zealand. http://www.physorg.com/news158584209.html Space & Earth Fri, 10 Apr 2009 12:10:57 EST news158584209 Durham University expert, Alex Densmore, is to explore the fault lines that caused the May 12th earthquake in China that killed 69,000 people. http://www.physorg.com/news137908630.html Space & Earth Thu, 14 Aug 2008 04:57:10 EST news137908630 (PhysOrg.com) -- Studying satellite radar data from ESA's Envisat and the Italian Space Agency's COSMO-SkyMed, scientists have begun analysing the movement of Earth during and after the 6.3 earthquake that shook the medieval town of L'Aquila in central Italy on 6 April 2009. http://www.physorg.com/news159015099.html Space & Earth Wed, 15 Apr 2009 11:52:41 EST news159015099 "When an earthquake strikes, hide under a table." "Don't rush outside immediately." Are these actually life-saving actions in an earthquake? The Education, Science and Technology Ministry plans to see if such commonly given advice stands up to scientific scrutiny. http://www.physorg.com/news164175142.html Other Sciences Sun, 14 Jun 2009 05:12:55 EST news164175142 In the last few years there has been a growing number of documented cases in which large earthquakes set off unfelt tremors in earthquake faults hundreds, sometimes even thousands, of miles away. http://www.physorg.com/news148136737.html Space & Earth Wed, 10 Dec 2008 13:05:37 EST news148136737 (PhysOrg.com) -- Researchers at the University of Michigan simulated an off-the-charts earthquake in a laboratory to test their new technique for bracing high-rise concrete buildings. Their technique passed the test, withstanding more movement than an earthquake would typically demand. http://www.physorg.com/news154888577.html Technology Thu, 26 Feb 2009 16:37:01 EST news154888577 A massive 7.8 magnitude earthquake last week has moved the south of New Zealand closer to Australia, scientists said Wednesday. http://www.physorg.com/news167460342.html Space & Earth Wed, 22 Jul 2009 05:46:09 EST news167460342 (AP) -- A strong earthquake jolted a swath of southern Alaska on Monday, sending people diving under desks and huddling in doorways but causing little damage. http://www.physorg.com/news164915519.html Space & Earth Mon, 22 Jun 2009 18:53:22 EST news164915519 (PhysOrg.com) -- When small earthquakes shake the central U.S., citizens often fear the rumbles are signs a big earthquake is coming. Fortunately, new research instead shows that most of these earthquakes are aftershocks of big earthquakes (magnitude 7) in the New Madrid seismic zone that struck the Midwest almost 200 years ago. http://www.physorg.com/news176564939.html Space & Earth Wed, 04 Nov 2009 13:49:32 EST news176564939 The 2007 Solomon Island earthquake may point to previously unknown increased earthquake and tsunami risks because of the unusual tectonic plate geography and the sudden change in direction of the earthquake, according to geoscientists. http://www.physorg.com/news158506384.html Space & Earth Thu, 09 Apr 2009 14:33:56 EST news158506384 From June 17-19th 2007, Kilauea experienced a new dike intrusion, where magma rapidly moved from a storage reservoir beneath the summit into the east rift zone and extended the rift zone by as much as 1 meter. http://www.physorg.com/news139226238.html Space & Earth Fri, 29 Aug 2008 10:57:18 EST news139226238
