Latest Seismology Stories
The more time it takes for an earthquake fault to heal, the faster the shake it will produce when it finally ruptures, according to a new study by engineers at the University of California, Berkeley, who conducted their work using a tabletop model of a quake fault.
Scientists have found evidence of a deadly tsunami that inundated coastal Switzerland in AD 563 after a rockfall near the River Rhone swept Lake Geneva.
The scientific community has largely dismissed weather-driven earthquakes as myths or relics of an earlier, more mystical society.
The May 2011 earthquake that struck near the Spanish town of Lorca and killed nine people could have been exacerbated by groundwater extraction, according to a new study from a team led by University of Western Ontario researchers.
Amid nuclear tensions, a seismic reality check
Engineers and city planners study surface geology in order to construct buildings that can respond safely to earthquakes.
NASA software that models the behavior of earthquake faults to improve earthquake forecasting and our understanding of earthquake processes, and NASA's first mobile application are co-winners of NASA's 2012 Software of the Year Award.

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...
