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...

New Study Reveals Quake-triggered Landslides Pose Significant Hazard For Seattle
2013-10-22 13:40:44

Seismological Society of America A new study suggests the next big quake on the Seattle fault may cause devastating damage from landslides, greater than previously thought and beyond the areas currently defined as prone to landslides. Published online Oct. 22 by the Bulletin of the Seismological Society of America (BSSA), the research offers a framework for simulating hundreds of earthquake scenarios for the Seattle area. "A major quake along the Seattle fault is among the worst case...

WorkSafe Technologies of Northern California understands Cal State's recent decision to demolish Warren Hall after being declared the most seismically unsafe structure in the university system. Hayward, CA (PRWEB) August 22, 2013 For over 20 years WorkSafe Technologies of Northern California has suggested to their customers "hope for the best, but prepare for the worst" when it comes to earthquakes. Non-structural seismic mitigation of a companies health and safety risks is...

Slow Earthquakes On San Andreas Fault Explained
2013-06-03 19:31:54

Woods Hole Oceanographic Institution New Zealand´s geologic hazards agency reported this week an ongoing, “silent” earthquake that began in January is still going strong. Though it is releasing the energy equivalent of a 7.0 earthquake, New Zealanders can´t feel it because its energy is being released over a long period of time, therefore slow, rather than a few short seconds. These so-called “slow slip events” are common at subduction zone faults...

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...

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...

Caltech researchers provide highest-resolution observations yet of the complex 2012 Sumatra earthquake The powerful magnitude-8.6 earthquake that shook Sumatra on April 11, 2012, was a seismic standout for many reasons, not the least of which is that it was larger than scientists thought an earthquake of its type could ever be. Now, researchers from the California Institute of Technology (Caltech) report on their findings from the first high-resolution observations of the underwater...

Researchers at the Carnegie Institution say that they have discovered a method of measuring and monitoring geological fault lines beneath the Earth's crust"”a development that could significantly enhance scientists' ability to accurately predict earthquakes. Geologists previously had no means with which to detect and measure the fluctuating strength of faults that are hidden beneath the Earth's surface.  Now, however, researchers from the Carnegie Institution's Department of...

When a swarm of hundreds of small to moderate earthquakes erupted beneath California's Salton Sea in March, sending spasms rumbling across the desert floor, it set off more than just seismometers. It also raised the eyebrows of quite a few concerned scientists. The reason: lurking underground, just a few kilometers to the northeast, lays a sleeping giant: the 160-kilometer-(100-mile) long southern segment of the notorious 1,300-kilometer- (800-mile) long San Andreas fault. Scientists were...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
