Los Angeles Earthquake Risks Studied Using 'Virtual Earthquake' Technique
2014-01-24 04:52:49

[ Watch the Video: Forecasting Los Angeles Earthquakes ] redOrbit Staff & Wire Reports - Your Universe Online A new technique developed by scientists at California’s Stanford University has confirmed that the Los Angeles would experience stronger-than-anticipated ground movement should major seismic activity occur to the city’s south, according to research published in the latest edition of Science. The method used weak vibrations generated by the Earth’s oceans to produce...

NASA JPL Scientist Reflects Last Big Quake In Los Angeles
2014-01-17 09:14:01

NASA's Jet Propulsion Laboratory Twenty years ago this week, in the predawn darkness of Jan. 17, 1994, at five seconds before 4:31 a.m. PST, the ground ruptured violently on a blind thrust fault (a crack in Earth's crust that does not reach the surface) about 11 miles (18 kilometers) beneath Reseda, in California's San Fernando Valley about 20 miles (31 kilometers) northwest of downtown Los Angeles. The resulting magnitude 6.7 earthquake, known as the Northridge earthquake, became the...

Earthquake Prone Regions Could Benefit From Updated Warning System

redOrbit Staff & Wire Reports - Your Universe Online Relocating some of the seismic stations in California and upgrading earthquake-detection technology could improve early warning systems throughout the state, according to new research appearing in the November edition of the the journal Seismological Research Letters. The effect would be particularly noticeable in regions that are poorly served by the current network, explained Serdar Kuyuk, assistant professor of civil...

North America Rocked By Two Major Earthquakes And Several Small Ones
2013-09-04 15:02:31

Lawrence LeBlond for redOrbit.com - Your Universe Online What started as a few small temblors that shook up Texas residents on Monday turned into an all-out rumble as three major earthquakes rocked parts of North America and Japan into Tuesday evening. One Texas temblor on Monday measured 4.1 magnitude, while the second measured 4.3 on the Richter scale. Neither of the quakes caused much in the way of significant damage and no injuries were reported. The USGS said both quakes occurred...

Slow Earthquakes May Predict Larger Events
2013-08-16 06:37:57

Penn State Monitoring slow earthquakes may provide a basis for reliable prediction in areas where slow quakes trigger normal earthquakes, according to Penn State geoscientists. "We currently don't have any way to remotely monitor when land faults are about to move," said Chris Marone, professor of geophysics. "This has the potential to change the game for earthquake monitoring and prediction, because if it is right and you can make the right predictions, it could be big." Marone and...

Powerful 7.8 Magnitude Earthquake Rocks Southeastern Iran
2013-04-16 08:48:18

Lawrence LeBlond for redOrbit.com - Your Universe Online A powerful 7.8 magnitude earthquake struck southeastern Iran, near the Pakistan border this morning at about 10:45 GMT (3:15 p.m. local time). Iran´s state-operated Press TV cited reports that at least 40 people are feared dead. However, the latest report from The Guardian said that number could be in the hundreds. The Iranian Seismological Center initially put the magnitude at 7.5, but an updated measurement of 7.8 was...

Landslides Triggered At Extraordinary Distances From 2011 Virginia Quake
2012-11-06 09:45:51

Seismological Society of America The 2011 Mineral, Virginia M-5.8 earthquake was felt over an extraordinarily large area. A new study details landslides triggered by the earthquake at distances four times greater and over an area 20 times larger than previously documented for M-5.8 earthquakes worldwide. The study, to be published in the December issue of the Bulletin of the Seismological Society of America (BSSA), describes physical confirmation of previous observations that ground...

Seismology
2014-01-12 00:00:00

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 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...
