Latest Seismology Stories
The National Research Council folded to pressure from the fossil fuel industry and pro-fracking Congress members last week by releasing a “more study needed” report on fracking and earthquakes.
Global seismic hazard maps exist to help societies and decision-makers anticipate and prepare for earthquakes.
Northern Italy on Tuesday was shaken by a magnitude 5.8 earthquake, killing at least ten people, less than two weeks after a magnitude 6.0 temblor rocked the same region, destroying castles, churches and leaving seven dead.
New dynamic computer model first to show full history of a fault segment
The space-based technology that lets GPS-equipped motorists constantly update their precise location will undergo a major test of its ability to rapidly pinpoint the location and magnitude of strong earthquakes across the western United States.
Fracking and injection wells are causing earthquakes around gas fields across the United States. This is a fact. Is it from waste-water injection wells or the production of gas? Geologists are not sure.
Things could get shaky as scientists will gather in San Diego next week to present their latest seismological research at the annual conference of the Seismological Society of America (SSA).
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...
