Earthquake Science: Predicting The Next ‘Big One’ For San Francisco
2014-05-20 06:42:38

Lawrence LeBlond for redOrbit.com - Your Universe Online The Great 1906 San Francisco earthquake released as much accumulated stress as a cluster of closely timed temblors did over a 100-year period in the seventeenth and eighteenth centuries. Based on this historical data, new research published in the Bulletin of the Seismological Society of America is looking at two possible scenarios for the San Francisco Bay Area’s next “Big One.” Study coauthor David Schwartz, a geologist...

California Groundwater Reliance Linked To Increased Earthquake Activity
2014-05-15 07:13:32

redOrbit Staff & Wire Reports - Your Universe Online Increased use of groundwater or pumping and irrigation could be increasing the number of small earthquakes occurring in California, and eventually speed-up the frequency of larger ones, according to new research appearing in the journal Nature. According to BBC News environmental correspondent Matt McGrath, the study found that extracting water for human activities has been causing mountains to lift and valleys to subside,...

Earthquakes Rattle California, Largest In 34 Years Hits Yellowstone
2014-03-31 11:15:34

Lawrence LeBlond for redOrbit.com - Your Universe Online CALIFORNIA As many as 30 earthquakes were recorded in California over the past 24 hours, most of which were less than a magnitude in intensity. Despite all the tremors regional seismometers pick up in California and Nevada -- 808 in the past week alone -- most go unnoticed by residents. The lack of a significant earthquake in the region also poses a problem to emergency management officials, who want Californians to be prepared...

San Francisco's 'Big One' In 1906 Was Third In A Series Of Quakes
2014-02-13 06:31:07

April Flowers for redOrbit.com - Your Universe Online Geologic evidence that supports historical narratives for two earthquakes in the 68 years prior to the 1906 quake that devastated San Francisco has been discovered by a research team led by the University of Oregon. The evidence, discovered by doctoral student Ashley R. Streig, places the two earthquakes—in 1838 and 1890—on the San Andreas Fault. Previously, many researchers had theorized this placement based on written accounts...

Latest ETV video features earthquake-resistant building, which literally rocks. San Francisco, CA (PRWEB) January 28, 2014 Sitting virtually astride California's infamous San Andreas Fault – the tectonic boundary between two massive geologic plates, the North American and the Pacific – San Francisco is no stranger to earthquakes. The City by The Bay and its surrounding communities were struck twice during the last century. The first one, in 1906, nearly destroyed the city...

Photographic Evidence, Lidar Helps Scientists More Accurately Locate San Andreas Fault Trace

Alan McStravick for redOrbit.com – your Universe Online At precisely 5:12 am on the morning of April 18, 1906, the northernmost 296 miles of the San Andreas Fault jolted many Californians from their sleep. The initial quake and catastrophic fires that followed are estimated to have sent nearly 3,000 to an early grave. Geologists claim this temblor to have been one of the most significant earthquakes of all time. This claim holds true when one considers that we are still learning from...

Humans Causing Seismic Activity
2013-07-12 08:57:39

Brett Smith for redOrbit.com - Your Universe Online Two studies published in the journal Science have both found human geologic activities could be causing nearby seismic activity. One study found that massive earthquakes from around the world have been triggering localized seismic events surrounding waste-fluid injection wells in the central United States. Large amounts of water are used in both hydrofracking and the more conventional mining of oil and gas from underground wells. After...

Why Some Quakes Shake Faster Revealed By Tabletop Fault Model
2012-10-31 15:28:04

University of California - Berkeley The more time it takes for an earthquake fault to heal, the faster the shake it will produce when it finally ruptures, according to a new study by engineers at the University of California, Berkeley, who conducted their work using a tabletop model of a quake fault. "The high frequency waves of an earthquake – the kind that produces the rapid jolts – are not well understood because they are more difficult to measure and more difficult to...

Lee Rannals for redOrbit.com — Your Universe Online Scientists are reviving a century old Tesla experiment by trying to recreate an earthquake through laboratory means. Nikola Tesla tried recreating earthquakes with his electro-mechanical oscillator, or "earthquake machine," back in 1898. He attached the device to building structures in a laboratory on Houston Street in New York. According to legend, the machine shook not only his building, but neighboring structures, leading...

Lawrence LeBlond for redOrbit.com - Your Universe Online UPDATE : 08-27-2012 10:00 a.m. (EST) Latest reports on the swarm of Southern California earthquakes puts the number at somewhere around 300, according to the USGS. The continuing series of temblors produced only minor damage, knocking trailers off their foundations and breaking windows. A few reports of cosmetic damage has also been reported on some older buildings. Most of the quakes were in the range of magnitude of 3.0,...
