Scientists Solve Mystery Of California Tectonics
2013-03-19 12:50:14

A team of American scientists believe they have solved a geological mystery buried about 100 miles below California.

Space Seismometer Recorded Japan's 2011 Earthquake, Two Years Ago Today
2013-03-11 14:58:19

Two years ago today, Japan was rocked by a 9.0-magnitude earthquake and giant tsunami that caused both death and destruction throughout the country. Now, with instrument's like the European Space Agency's GOCE satellite, scientists will be able to understand a bit more about these devastating quakes.

Waves Generated By Russian Meteor Recorded Crossing The US
2013-03-07 13:29:53

A network of seismographic stations recorded spectacular signals from the blast waves of the meteor that landed near Chelyabinsk, Russia, as the waves crossed the United States.

Russian Meteor Is The Largest Ever Detected By CTBTO’s Infrasound Sensors
2013-02-19 12:31:59

Infrasonic waves from the meteor that broke up over Russia’s Ural mountains last week were the largest ever recorded by the CTBTO’s International Monitoring System.

Geologic Facelift For Appalachian Mountain Basin
2013-02-01 08:45:25

Despite the absence of any recent tectonic activity in the area, one region of the Appalachian Mountains looks vastly different from its surroundings, leading a team of US researchers to conclude that the location had undergone a transformation they refer to as a “geological facelift.”

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.

2012-12-28 15:13:47

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.

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...
