American Heartland At High Risk For Sizable Earthquakes
2013-09-30 14:15:26

[ Watch the Video: Earthquake Risks In America's Heartland ] Lawrence LeBlond for redOrbit.com - Your Universe Online An earthquake zone that extends from Marked Tree, Arkansas to Paducah, Kentucky and as far south as Memphis, Tennessee has a higher earthquake risk than adjacent areas within the United States, according to new research from the US Geological Survey (USGS). Using sophisticated technology, USGS scientists have developed new high-resolution images of the New Madrid...

Brett Smith for redOrbit.com - Your Universe Online Folks living near the Mississippi River where Arkansas, Tennessee, Missouri and Kentucky converge should expect to see a low-flying, red-and-white Cessna today. Do not be alarmed, U.S. Geological Survey officials announced. The region, known as the New Madrid seismic zone, is of particular interest to geologists and the federal agency is using low-level flights, being performed by specially trained pilots, to detect subtle local...

News from the Seismological Society of America 2013 Annual Meeting 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. At the annual meeting of the...

In The Last 300,000 Years The Alhama de Murcia Fault Has Experienced At Least 6 Major Earthquakes
2012-11-12 13:13:08

FECYT - Spanish Foundation for Science and Technology Enjoying Spanish participation, an international group of researchers have analyzed the most recent history of the Alhama de Murcia fault. They discovered that it has experienced six major earthquakes above 7 on the Richter scale. According to the scientists, this provides "convincing evidence" that the maximum earthquake magnitudes in the area are higher than originally thought. Since 2001, researchers from the Universities of...

2000 years of Chinese records shows migrating mid-continent earthquakes This December marks the bicentennial of the New Madrid earthquakes of 1811-12, which are the biggest earthquakes known to have occurred in the central U.S. Now, based on the earthquake record in China, a University of Missouri researcher says that mid-continent earthquakes tend to move among fault systems, so the next big earthquake in the central U.S. may actually occur someplace else other than along the New Madrid...

Central Arkansas has been hit with a series of earthquakes recently, more than 500 since September 20. According to the U.S. Geological Survey (USGS), most were hardly noticeable but one stood out prominently when it hit the Richter scale at a 4.0 on October 11. Geologists can't say whether the quakes will end anytime soon. Dr. Horton of the University of Memphis feels that the ample amount of earthquakes in this state is quite unusual. "In the New Madrid Seismic Zone there's approximately...

Researchers said on Wednesday that the risk of earthquakes in the U.S. Midwest may be more widespread than geologists had previously thought.  They found that swept away sediments at the end of the last ice age could have triggered a series of large earthquakes that started in 1811 in the New Madrid seismic zone. They reported in the journal Nature that this suggests these fault segments are unlikely to fail again soon, but the same process could trigger earthquakes on nearby fault...

U.S. scientists say the New Madrid seismologic fault system in the Midwest and South may be in the process of shutting down. Purdue and Northwestern University researchers have been using global positioning system measurements to determine the earthquake risk to parts of Illinois, Indiana, Tennessee, Arkansas and Kentucky. The fault motion has been much less than expected, Purdue researchers said Friday. The last major earthquake in the New Madrid seismic zone was in 1812. Our findings...


Word of the Day
call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
