Latest Seismology Stories
A team of U.S., Mexican, and Chinese geologists have used a new tool to help pinpoint the precise locations where earthquakes caused the planet's crust to rupture and alter the landscape, resulting in what they are calling the "most comprehensive before-and-after picture… of an earthquake zone to date."
2010 Haiti quake possible start of new cycle of seismic activity, according to new study.
Japan’s capital city, Tokyo, has a high probability of experiencing a magnitude-7 earthquake within just a few years, according to Japanese scientists.
Last year, earthquakes and their consequences, such as tsunamis, landslides, and ground settlements, caused a damage of 365 billion US dollars.
Geophysicists from Potsdam have established a mode of action that can explain the irregular distribution of strong earthquakes at the San Andreas Fault in California.
"You know you are from Christchurch when…" you manage to keep your sense of humor through a year of nonstop hardship.
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...
