Latest Seismology Stories
The region of Chile that was rocked by an earthquake last February could be at risk for a larger series of tremors.
One year ago, a massive earthquake devastated Haiti.
Careful analysis shows seismometer noise includes signals from storms in the South Atlantic and 'footquakes' from soccer matches.
A new assessment of global earthquake fatalities over the past three decades indicates that 83 percent of all deaths caused by the collapse of buildings during earthquakes occurred in countries considered to be unusually corrupt.
The Moon, Earth's closest neighbor, has long been studied to help us better understand our own planet.
New technologies developed by NASA and other agencies are revealing surprising insights into a major earthquake that rocked parts of the American Southwest and Mexico in April, including increased potential for more large earthquakes in Southern California.
Geologists from the University of Rhode Island and Princeton University, in collaboration with Lawrence Livermore National Laboratory, have taken an important step toward helping the United States government monitor nuclear explosions by improving a 3-dimensional model originally developed at Harvard University.
As the US policy makers renew emphasis on the use of nuclear energy in their efforts to reduce the country's oil dependence, other factors come into play.
Researchers from the Universidad Pablo de Olavide (UPO) and the Universidad de Sevilla (US) have found patterns of behavior that occur before an earthquake on the Iberian peninsula.
The devastating 2008 Wenchuan earthquake marks a defining moment for China's earthquake science program.
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...
