Salt Lake Valley, home to the Salt Lake City segment of the Wasatch fault zone and the West Valley fault zone, has been the site of repeated surface-faulting earthquakes (of about magnitude 6.5 to 7). New research trenches in the area are helping geologists and seismologists untangle how this complex fault system ruptures and will aid in forecasting future earthquakes in the area. http://phys.org/news285354106.html Space & Earth Wed, 17 Apr 2013 00:10:01 EST news285354106 Recent paleoseismic work has documented four surface-rupturing earthquakes that occurred across the Santa Cruz Mountains section of the San Andreas Fault (SAF) in the past 500 years. The research, conducted by the U.S. Geological Survey, with assistance from the California Geological Survey, suggests an average recurrence rate of 125 years, indicating the seismic hazard for the area may be significantly higher than currently recognized. The observations help fill a gap in data on the seismic activity of the SAF in northern California, particularly south of San Francisco. http://phys.org/news257602925.html Space & Earth Wed, 30 May 2012 13:22:31 EST news257602925 At the Hikurangi fault, off the eastern coast of New Zealand's North Island, the Pacific tectonic plate sinks beneath the Australian plate. Farther south, in the Marlborough Fault System, which cuts through the country's larger South Island, the interaction between the two slabs turns such that the plates grind edge-on. http://phys.org/news251398505.html Space & Earth Mon, 19 Mar 2012 18:30:01 EST news251398505 The 2010 earthquake that devastated southern Haiti may have opened a new era of seismic activity and residents should brace for more massive temblors, said a US study on Thursday. http://phys.org/news246814556.html Space & Earth Thu, 26 Jan 2012 15:36:13 EST news246814556 (PhysOrg.com) -- The topography surrounding the Laguna Salada fault in the Mexican state of Baja, California, is clearly shown in this combined radar image and topographic view (above) generated with data from NASA's Shuttle Radar Topography Mission (SRTM). On April 4, 2010, a magnitude 7.2 earthquake struck along this fault about 64 kilometers (40 miles) south of the Mexico-United States border. http://phys.org/news189754618.html Space & Earth Tue, 06 Apr 2010 10:40:01 EST news189754618 (PhysOrg.com) -- Current earthquake prediction methods may need to be revised in the wake of the recent Haiti and Asian earthquakes and tsunami. http://phys.org/news182687497.html Space & Earth Thu, 14 Jan 2010 10:31:56 EST news182687497 (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://phys.org/news176721098.html Space & Earth Fri, 06 Nov 2009 09:19:52 EST news176721098 (PhysOrg.com) -- The New Madrid fault system does not behave as earthquake hazard models assume and may be in the process of shutting down, a new study shows. http://phys.org/news156169464.html Space & Earth Fri, 13 Mar 2009 13:24:56 EST news156169464
