Latest Seismology Stories
Learning from history, TAU invention can improve earthquake prediction today.
While Japanâ€™s massive earthquake and accompanying tsunami represent a devastating natural disaster for the countryâ€™s residents, scientists should also seize upon the massive temblor as an important learning tool for future quakes around the world, including the Pacific Northwest coast of the United States.

The Christchurch, New Zealand earthquake that took place on February 22 has been illustrated in new radar imagery.
By studying seismographs from the earthquake that hit Chile last February, earth scientists at the Georgia Institute of Technology have found a statistically significant increase of microearthquakes in central California in the first few hours after the main shock.
A day after a powerful earthquake rocked Christchurch on Feb 22, 2011, the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on NASA's Terra spacecraft imaged the Christchurch region.
The terribly destructive earthquake that just hit Christchurch, New Zealand, was only a moderate 6.3 magnitude, but had certain characteristics that offer an important lesson to cities up and down the West Coast of North America that face similar risks, experts say.
The official death toll resulting from Tuesday's earthquake in the New Zealand city of Christchurch has climbed to 75, but that number is expected to rise even more--especially now that police called off the search for survivors at a television office building
New research gives the first accurate estimate of how much faster the Earth's core is rotating compared to the rest of the planet.
HOUSTON, Feb. 15, 2011 /PRNewswire/ -- ION Geophysical Corporation (NYSE: IO) today announced that its GX Technology (GXT) Imaging Solutions group has established a new seismic data processing center in Rio de Janeiro.
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...
