Latest Seismology Stories
Researchers from Washington University in St. Louis, Missouri have found that giant ice avalanches on Saturn's moon Iapetus could provide clues to slippage in other places in the Solar System.
The most dangerous fault line on the island of New Zealand is the Alpine Fault.
Caltech researchers provide highest-resolution observations yet of the complex 2012 Sumatra earthquake
Although the earth is shaken by approximately 80,000 earthquakes every month, not many of them will send you running for the nearest doorway. However, scientists, led by a team at Karlsruhe Institute of Technology (KIT) in Germany, have recently started investing more time and research into understanding these subtle vibrations that occur deep in the Earth’s crust.
Seismic risk not only depends on the magnitude of the tremor itself but also on the resistance of buildings and the social characteristics of its population.
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.
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...
