The faint tug of the sun and moon on the San Andreas Fault stimulates tremors deep underground, suggesting that the rock 15 miles below is lubricated with highly pressurized water that allows the rock to slip with little effort, according to a new study by University of California, Berkeley, seismologists. http://www.physorg.com/news180785622.html Space & Earth Wed, 23 Dec 2009 13:30:01 EST news180785622 Some geologic faults that appear strong and stable, slip and slide like weak faults. Now an international team of researchers has laboratory evidence showing why some faults that "should not" slip are weaker than previously thought. http://www.physorg.com/news180193925.html Space & Earth Wed, 16 Dec 2009 14:40:01 EST news180193925 Natural gas that lies under Turkey's Marmara Sea close to Istanbul could provide advance warning of an earthquake experts believe will hit the country's largest city, scientists said on Tuesday. http://www.physorg.com/news180113726.html Space & Earth Tue, 15 Dec 2009 15:36:22 EST news180113726 Most earthquakes occur along fault lines, which form boundaries between two tectonic plates. As the relative speed of the plates around a fault increases, is there a corresponding increase in the number of earthquakes produced along the fault? According to this study published in the December issue of BSSA, the answer depends upon the type of tectonic boundary. On certain types of boundary, the efficiency of earthquake production actually depends on the fault slip rate. http://www.physorg.com/news179151968.html Space & Earth Fri, 04 Dec 2009 12:50:02 EST news179151968 (PhysOrg.com) -- The third in a series of papers in the journal Nature completes the case for a new method of predicting earthquakes. http://www.physorg.com/news179087953.html Space & Earth Thu, 03 Dec 2009 18:41:47 EST news179087953 A team of Spanish scientists, studying recent, active deformations in the Baetic mountain range, have shown that the activity of smaller tectonic structures close to larger faults in the south east of the Iberian Peninsula partially offsets the risk of earthquakes. http://www.physorg.com/news178368974.html Space & Earth Wed, 25 Nov 2009 10:57:11 EST news178368974 (PhysOrg.com) -- Using a technique normally used for detecting weak tremor, scientists at the Georgia Institute of Technology discovered that the 2004 magnitude 6 earthquake along the Parkfield section of the San Andreas fault exhibited almost 11 times more aftershocks than previously thought. The research appears online in Nature Geoscience and will appear in print in a forthcoming edition. http://www.physorg.com/news178201188.html Space & Earth Mon, 23 Nov 2009 12:50:07 EST news178201188 (AP) -- The world's largest atom smasher made another leap forward Monday by circulating beams of protons in opposite directions at the same time in the $10 billion machine after more than a year of repairs, organizers said. http://www.physorg.com/news178198886.html Physics Mon, 23 Nov 2009 11:42:04 EST news178198886 (AP) -- Scientists are preparing the world's largest atom smasher to explore the depths of matter after successfully restarting the $10 billion machine following more than a year of repairs. http://www.physorg.com/news178024871.html Physics Sat, 21 Nov 2009 11:21:52 EST news178024871 A state-of-the-art underwater robot called BOB may hold the key to protecting millions of people around Turkey's biggest city against a massive earthquake scientists say is all but inevitable. http://www.physorg.com/news177394319.html Space & Earth Sat, 14 Nov 2009 04:40:01 EST news177394319 With an average of four mini-earthquakes per day, Southern California's San Jacinto fault constantly adjusts to make it a less likely candidate for a major earthquake than its quiet neighbor to the east, the Southern San Andreas fault, according to an article in the journal Nature Geoscience. http://www.physorg.com/news176908962.html Space & Earth Sun, 08 Nov 2009 13:23:32 EST news176908962 (PhysOrg.com) -- Mars Express flew over the boundary between Kasei Valles and Sacra Fossae and imaged the region, acquiring spectacular views of the chaotic terrain in the area. http://www.physorg.com/news176721098.html Space & Earth Fri, 06 Nov 2009 09:19:52 EST news176721098 (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 (PhysOrg.com) -- New research on the Kitsap Peninsula, at the west edge of Washington state's Puget Sound, finds evidence that land was raised at least 6 feet by ancient earthquakes. http://www.physorg.com/news175195166.html Space & Earth Mon, 19 Oct 2009 18:20:05 EST news175195166 Using satellite radar data and GPS measurements, Chinese researchers have explained the exceptional geological events leading to the 2008 Wenchuan Earthquake that killed nearly 90 000 people in China's Sichuan Province. http://www.physorg.com/news174821357.html Space & Earth Thu, 15 Oct 2009 11:20:02 EST news174821357 Scientists at the Carnegie Institution have found a way to monitor the strength of geologic faults deep in the Earth. This finding could prove to be a boon for earthquake prediction by pinpointing those faults that are likely to fail and produce earthquakes. Until now, scientists had no method for detecting changes in fault strength, which is not measureable at the Earth's surface. http://www.physorg.com/news173539022.html Space & Earth Thu, 01 Oct 2009 14:20:01 EST news173539022 (PhysOrg.com) -- U.S. seismologists have found evidence that the massive 2004 earthquake that triggered killer tsunamis throughout the Indian Ocean weakened at least a portion of California's famed San Andreas Fault. The results, which appear this week in the journal Nature, suggest that the Earth's largest earthquakes can weaken fault zones worldwide and may trigger periods of increased global seismic activity. http://www.physorg.com/news173534942.html Space & Earth Wed, 30 Sep 2009 13:11:29 EST news173534942 People who were killed, injured or bereaved in the 2008 Sichuan earthquake had the cruel misfortune to be victims of an event that probably occurs just once in four millennia, seismologists said on Sunday. http://www.physorg.com/news173281082.html Space & Earth Sun, 27 Sep 2009 14:38:37 EST news173281082 An international team of researchers has created the most complete seismic image of the Earth's crust and upper mantle beneath the rugged Himalaya Mountains, in the process discovering some unusual geologic features that may explain how the region has evolved. http://www.physorg.com/news171899385.html Space & Earth Fri, 11 Sep 2009 14:50:22 EST news171899385 (PhysOrg.com) -- Some slow-moving faults may help protect some regions of Italy and other parts of the world against destructive earthquakes, suggests new research from The University of Arizona in Tucson. http://www.physorg.com/news170672915.html Space & Earth Fri, 28 Aug 2009 10:09:53 EST news170672915 (PhysOrg.com) -- To protect their systems from network failures and to make sure that their data is delivered as fast as possible, popular services such as Google may replicate their data centers on multiple continents and at multiple sites based on their proximity to population centers. This presents two critical challenges for network systems researchers: interconnecting multiple computers within a single data center; and synchronizing individual data centers in wide-area replication. http://www.physorg.com/news170618017.html Technology Thu, 27 Aug 2009 19:10:01 EST news170618017 (PhysOrg.com) -- As the amounts of data being stored by databases around the world enters the realm of the petabyte (the amount of data stored in a mile-high stack of CD-ROM disks), efficient data management is becoming more and more important. Now computer scientists at Yale University have developed a new database system by combining the best features of multiple approaches to create an open source hybrid system called HadoopDB. http://www.physorg.com/news170525347.html Technology Wed, 26 Aug 2009 17:09:43 EST news170525347 Powerful earthquakes that have jolted Asia recently do not presage a disaster, although it is only a matter of time before the next catastrophe befalls the quake-prone region, seismologists say. http://www.physorg.com/news170257984.html Space & Earth Sun, 23 Aug 2009 14:54:02 EST news170257984 University of California, San Diego computer scientists have created software that they hope will lead to data centers that logically function as single, plug-and-play networks that will scale to the massive scale of modern data center networks.
