Multi-Study Focuses On Link Between Lushan, Wenchuan Earthquakes
2014-01-03 09:30:34

New research, published in Seismological Research Letters, suggests that the 32-mile segment of the fault northeast of the 2013 Lushan rupture is the place to watch for the next major earthquake in the region.

Subvertical Faults Can Create Electrical Light Shows During Earthquakes
2014-01-03 05:56:52

A new study, published in Seismological Research Letters, reveals that rare earthquake lights are more likely to occur on or near rift environments. These environments are where subvertical faults allow stress-induced electrical currents to flow rapidly to the surface.

Runaway Earthquakes Helped By High Pressure Heating
2013-12-25 05:01:27

Almost one quarter of all earthquakes start in the lithosphere, a slice of the Earth about 31 miles below the surface. Scientists have now revealed the discovery of a mechanism that helps deep rumblings in the lithosphere spread into larger quakes.

One In Four Earthquakes Worldwide Come From Deep Within Earth
2013-12-12 08:16:04

The long standing mystery of what drives a particular type of earthquake that occurs deep within the Earth and accounts for one in four quakes worldwide might have been solved by a team led by Stanford researchers.

Japanese Earthquake And Tsunami
2013-12-06 04:37:35

The magnitude 9.0 Tohoku-Oki earthquake that occurred off the Japanese coast in March 2011, triggering a tsunami and ultimately resulting in more than 15,000 deaths, was the result of the largest fault slip ever recorded.

Earthquake Prone Regions Could Benefit From Updated Warning System
2013-10-31 08:52:18

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.

Google Street View Tool Used To Record Earthquake Damage
2013-10-30 11:13:09

A scientist from Cologne University has used Google's online street view scans to document the damage caused by the 2009 L'Aquila earthquake and suggests that the database would be a useful tool for surveying damage caused by future earthquakes.

New Study Reveals Quake-triggered Landslides Pose Significant Hazard For Seattle
2013-10-22 13:40:44

A new study suggests the next big quake on the Seattle fault may cause devastating damage from landslides, greater than previously thought and beyond the areas currently defined as prone to landslides.

Powerful Earthquake Rocks Philippines On National Holiday
2013-10-15 06:59:43

A powerful 7.1-magnitude earthquake rocked the Philippines Tuesday morning, killing at least 85 people and injuring hundreds more. The USGS said the quake was centered near the town of Catigbian at about 12 miles deep.

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...
