A trio of earthquakes that stuck Central and Southern California on Friday morning caused no damage and were apparently unrelated.
Scientists are reviving a century old Tesla experiment by trying to recreate an earthquake through laboratory means.
As this weekend's earthquakes still captivate the headlines, a new program is emerging that implores citizens to act as scientists to try and predict the next big quake.
A swarm of moderately-sized earthquakes struck Imperial County, north of El Centro, California late Sunday morning and early Sunday afternoon, according to the US Geological Survey.
Glacierologists said their recent study not only provides a window into the behavior of glaciers—it also could be used as a simple model for the mechanism behind slip-stick earthquakes.
A new study from Arizona State University found nearly 1,000 earthquakes rattling the state over a three-year period.
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...
