Latest Seismology Stories
Japan's March 11 Tohoku Earthquake is among the strongest ever recorded, and because it struck one of the world's most heavily instrumented seismic zones, this natural disaster is providing scientists with a treasure trove of data on rare magnitude 9 earthquakes.
SCOTTSDALE, Ariz., July 15, 2011 /PRNewswire/ -- Digitexx Data Systems, Inc. has launched REFLEXX Smart System for Buildings, a new damage detection and performance evaluation reporting system that provides essential structural health data in less than 15 minutes.
Study finds that faults beneath the Salton Sea ruptured during Colorado River floods and may have triggered large earthquakes on the southern San Andreas Fault.
A series of powerful aftershocks rocked the already quake-battered New Zealand city of Christchurch Monday, destroying one of the few remaining buildings downtown and throwing thousands of residents into darkness.
An unusual signal detected results from waves in Lake Gatun, the reservoir that forms the Panama Canal channel.
Japanâ€™s recent magnitude 9 earthquake, which triggered a devastating tsunami, relieved stress along part of the quake fault but also has contributed to the buildup of stress in other areas, putting some of the country at risk for up to years of sizeable aftershocks and perhaps new main shocks.
The magnitude 9 earthquake and resulting tsunami that struck Japan on March 11 were like a one-two punch â€“ first violently shaking, then swamping the islands â€“ causing tens of thousands of deaths and hundreds of billions of dollars in damage.
VIENNA, May 25, 2011 /PRNewswire/ -- Paradigm(TM)(www.pdgm.com)announced today the signing of a multi-year software license agreement with JKX Oil & Gas plc (www.jkx.co.uk) for a seismic-to-simulation workflow to be deployed as the company's standard toolkit.
VANCOUVER, May 19 /PRNewswire/ - Kimber Resources Inc.
Bolivia may need to prepare for a possible megaquake that would be 125 times more powerful than previously calculated.
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...
