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...

Lee Rannals for redOrbit.com - Your Universe Online University of Liverpool scientists believe that up to three and a half times the water of all the Earth’s oceans could be being transported beneath our feet. Seismologists reported in the journal Geology that they found deep sea fault zones could transport much larger amounts of water from Earth’s oceans to the upper mantle than previously thought. The team analyzed earthquakes that occurred more than 60 miles below the Earth’s...

Los Angeles Earthquake Risks Studied Using 'Virtual Earthquake' Technique

[ 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...

Georgia Basin May Amplify Ground Shaking From Next Quake In Vancouver
2014-01-21 08:15:38

Seismological Society of America Tall buildings, bridges and other long-period structures in Greater Vancouver may experience greater shaking from large (M 6.8 +) earthquakes than previously thought due to the amplification of surface waves passing through the Georgia basin, according to two studies published by the Bulletin of the Seismological Society of America (BSSA). The basin will have the greatest impact on ground motion passing over it from earthquakes generated south and southwest...

NASA JPL Scientist Reflects Last Big Quake In Los Angeles
2014-01-17 09:14:01

NASA's Jet Propulsion Laboratory Twenty years ago this week, in the predawn darkness of Jan. 17, 1994, at five seconds before 4:31 a.m. PST, the ground ruptured violently on a blind thrust fault (a crack in Earth's crust that does not reach the surface) about 11 miles (18 kilometers) beneath Reseda, in California's San Fernando Valley about 20 miles (31 kilometers) northwest of downtown Los Angeles. The resulting magnitude 6.7 earthquake, known as the Northridge earthquake, became the...

Seismology is the scientific study of earthquakes and the spread of elastic waves through the Earth or through other planet-like bodies. The field includes studies of earthquake effects, such as tsunamis in addition to diverse seismic sources such as tectonic, volcanic, oceanic, atmospheric, and artificial processes. A related field that utilizes geology to infer information regarding past earthquakes is paleoseismology. A recording of earth motion as a function of time is a seismogram. A...

The Richter scale assigns a single number to quantify the amount of seismic energy released by an earthquake. The scale uses a base-10 logarithm by calculating the logarithm of the combined horizontal amplitude of the largest displacement from zero on a particular type of seismometer. A earthquake measuring 5.0 on the Richter scale has a shaking amplitude 10 times larger than one that measures 4.0. The moment magnitude, calibrated to give generally similar value for medium-sized...

The Seismometer is an instrument designed to measure the motions of the ground. This includes seismic waves generated by earthquakes, nuclear explosions, and other seismic sources. Records of these activities allow seismologists to map the interior of the Earth, and locate and measure the size of the different sources. There are also seismographs, which is sometimes used in place of the word seismometer. However, a seismograph is the older instrument in which the measuring and recording...
