San Andreas Fault Wouldn't Stop Statewide California Quake
2013-01-12 07:54:47

Assumptions that the San Andreas Fault would automatically prevent an earthquake from affecting both northern and southern California at the same time may not necessarily be true.

Himalayas Will Have More Massive Earthquakes, Warn Scientists
2012-12-31 11:33:53

An international team of researchers has found that a pair of massive, historical earthquakes ruptured the surface in the central Himalayas.

A research team led by scientists from Nanyang Technological University (NTU) has discovered that massive earthquakes in the range of 8 to 8.5 magnitudes on the Richter scale have left clear ground scars in the central Himalayas.

Using Seismic Waves To Detect Tunnels Is Not As Simple As It Sounds
2012-12-10 15:01:35

You’d think it would be easy to use seismic waves to find tunnels dug by smugglers of drugs, weapons or people. You’d be wrong.

Scientists have long used the speed of seismic waves traveling through the Earth as a means of learning about the geologic structure beneath the Earth's surface, but the seismic waves they use have typically been generated by earthquakes or man-made explosions.

Scientists Warn Of Major Earthquakes In Himalayas And Pacific Northwest
2012-12-04 15:18:09

Scientists at the American Geophysical Union meeting in San Francisco this week reported that the Himalayas and Pacific Northwest could experience major earthquakes.

In The Last 300,000 Years The Alhama de Murcia Fault Has Experienced At Least 6 Major Earthquakes
2012-11-12 13:13:08

Enjoying Spanish participation, an international group of researchers have analyzed the most recent history of the Alhama de Murcia fault.

Landslides Triggered At Extraordinary Distances From 2011 Virginia Quake

The 2011 Mineral, Virginia M-5.8 earthquake was felt over an extraordinarily large area.

Why Some Quakes Shake Faster Revealed By Tabletop Fault Model
2012-10-31 15:28:04

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.

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 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...
