A new National Research Council report presents a 20-year road map for increasing U.S. resilience to earthquakes, including a major earthquake that could strike a highly populated area.
Mega-quakes, such as the recent massive temblor off the coast of Japan are not expected to set off other large quakes in distant regions of the world.
AccuConference is offering free calls to Japan in the wake of the earthquake, Tsunami and nuclear crisis taking place there.
An earthquake struck Myanmar on Thursday night, shaking buildings as far away as Bangkok.
Geologists say the earthquake that rocked Japan on March 11 has altered the earth's surface and loaded more stress on a fault line much closer to Tokyo.

CHATSWORTH, Calif., March 16, 2011 /PRNewswire/ -- On March 11, 2011 Japan experienced the largest earthquake ever in its history, a 9.0 magnitude off the coast of Honshu, Japan.
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...
