Latest Seismology Stories
Two studies published in the journal Science have both found human geologic activities could be causing nearby seismic activity.
The U.S. Geological Survey (USGS) and other scientific institutions are using social media and crowdsourcing to learn more about earthquakes.
Folks living near the New Madrid seismic zone should expect to see a low-flying, red-and-white Cessna today. Do not be alarmed, U.S. Geological Survey officials announced.
Earthquake researchers have now identified a 30 kilometers long and ten kilometers deep area along the North Anatolian fault zone just south of Istanbul that could be the starting point for a strong earthquake.
According to a new report, two researchers have identified key acoustic characteristics of the 2011 Japan earthquake that could be used to significantly improve tsunami warning systems.
Colombia sits atop a complex geological area where three tectonic plates are interacting, producing seismicity patterns that have puzzled seismologists for years.
Researchers have been aware of slow earthquakes for only the past decade, but little has been understood about them. However, new tools may help explain what triggers these quakes.
Researchers writing in the journal Geophysical Research Letters say the western Indian Ocean earthquake and tsunami hazard potential is greater than scientists had originally predicted.
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...
