Evidence Of Super-fast Deep Earthquake Discovered By Scripps Scientists
2014-07-14 08:49:39

University of California - San Diego Rare high-speed rupture off Russia provides clues about similar phenomena on shallow fault zones near Earth's surface As scientists learn more about earthquakes that rupture at fault zones near the planet's surface—and the mechanisms that trigger them—an even more intriguing earthquake mystery lies deeper in the planet. Scientists at Scripps Institution of Oceanography at UC San Diego have discovered the first evidence that deep earthquakes,...

Seismological Society of America Natural earthquakes and nuclear explosions produce seismic waves that register on seismic monitoring networks around the globe, allowing the scientific community to pinpoint the location of the events. In order to distinguish seismic waves produced by a variety of activities – from traffic to mining to explosions – scientists study the seismic waves generated by as many types of events as possible. In August 2012, the emergence of a very large...

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...

Fracking May Pose Greater Earthquake Risk Than Previously Believed
2014-05-04 06:04:05

redOrbit Staff & Wire Reports - Your Universe Online The risk of fracking-related underground wastewater disposal could pose a far greater risk of causing earthquakes than experts have previously realized, especially in the US Southwest and Midwest, scientists revealed Thursday at the annual Seismological Society of America (SSA) conference. According to Patrick J. Kiger of National Geographic, the reason why those regions are the most at-risk is because the fault lines there have...

Man-made quakes need to be included in seismic hazard planning say experts Oil and gas development activities, including underground disposal of wastewater and hydraulic fracturing, may induce earthquakes by changing the state of stress on existing faults to the point of failure. Earthquakes from wastewater disposal may be triggered at tens of kilometers from the wellbore, which is a greater range than previously thought, according to research to be presented today at the annual meeting of...

Accidental Find Offers Big Potential For Research On Alaska's Glaciers
2014-05-01 03:38:49

Seismological Society of America Alaska's seismic network records thousands of quakes produced by glaciers, capturing valuable data that scientists could use to better understand their behavior, but instead their seismic signals are set aside as oddities. The current earthquake monitoring system could be "tweaked" to target the dynamic movement of the state's glaciers, suggests State Seismologist Michael West, who will present his research today at the annual meeting of the Seismological...

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...
