Latest Seismology Stories
A massive earthquake that affected the Maule region of Chile in February 2010 also unleashed a series of smaller seismic events known as “icequakes” nearly 3,000 to the south in Antarctica, a team of researchers report in a new Nature Geoscience study.
A 70-foot-long, 52-ton concrete bridge survived a series of earthquakes in the first multiple-shake-table experiment in the University of Nevada, Reno's new Earthquake Engineering Lab, the newest addition to the world-renowned earthquake/seismic engineering facility.
Rare high-speed rupture off Russia provides clues about similar phenomena on shallow fault zones near Earth's surface
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.
HOUSTON, July 1, 2014 /PRNewswire/ -- Virtus Oil and Gas Corporation (OTCBB: VOIL) ("Virtus" or the "Company") today announced it has entered into an agreement with Seismic Exchange, Inc.
Saddleback continues its alliance with INT by providing Attribute::Toolbox™ to all licensed users of INTViewer™. Houston, Texas (PRWEB) June 16, 2014
HOUSTON and RIO DE JANEIRO, June 16, 2014 /PRNewswire/ -- OceanGeo B.V., a geophysical company specializing in multicomponent ocean bottom seismic (OBS) acquisition, today announced that
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.
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.
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.
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...
