Science China Press Chinese and American scientists collaborating in the study of an active seismic fault that produced one of China's most deadly earthquakes say their deployment of an airborne LiDAR system, which uses pulses of laser light to calculate distances and chart terrain features, has helped them produce the most precise topographical measurements ever of the fault zone. "Light detection and ranging (LiDAR) presents a new approach to build detailed topographic maps...

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,...

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...

Los Angeles Earthquake Risks Studied Using 'Virtual Earthquake' Technique
2014-01-24 04:52:49

[ Watch the Video: Forecasting Los Angeles Earthquakes ] redOrbit Staff & Wire Reports - Your Universe Online A new technique developed by scientists at California’s Stanford University has confirmed that the Los Angeles would experience stronger-than-anticipated ground movement should major seismic activity occur to the city’s south, according to research published in the latest edition of Science. The method used weak vibrations generated by the Earth’s oceans to produce...

Subvertical Faults Can Create Electrical Light Shows During Earthquakes
2014-01-03 05:56:52

April Flowers for redOrbit.com - Your Universe Online A new study, published in Seismological Research Letters, reveals that rare earthquake lights are more likely to occur on or near rift environments. These environments are where subvertical faults allow stress-induced electrical currents to flow rapidly to the surface. Scholars have been intrigued by the luminous phenomena known as earthquake lights (EQL) since the earliest days of seismology. EQL appear before or during earthquakes,...

One In Four Earthquakes Worldwide Come From Deep Within Earth
2013-12-12 08:16:04

April Flowers for redOrbit.com - Your Universe Online The long standing mystery of what drives a particular type of earthquake that occurs deep within the Earth and accounts for one in four quakes worldwide might have been solved by a team led by Stanford researchers. Their findings are published in an upcoming issue of Geophysical Research Letters. Originating farther inside the planet than shallow earthquakes, these temblors are known as intermediate-depth earthquakes. Shallow...

Japanese Earthquake And Tsunami

[ Watch the Video: What Is At Fault For The 2011 Fukushima Earthquake And Tsunami? ] redOrbit Staff & Wire Reports - Your Universe Online The magnitude 9.0 Tohoku-Oki earthquake that occurred off the Japanese coast in March 2011, triggering a tsunami and ultimately resulting in more than 15,000 deaths, was the result of the largest fault slip ever recorded, according to a trio of studies published Thursday in the journal Science. According to Jane J. Lee of National Geographic,...

Photographic Evidence, Lidar Helps Scientists More Accurately Locate San Andreas Fault Trace
2013-11-27 19:21:53

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...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
