Current Seismic Activity News Events, Discoveries and Articles
China quake rare and unexpected, says new MIT study
A new analysis of the setting for last month's devastating earthquake in China by a team of geoscientists at MIT shows that the quake resulted from faults with little seismic activity, and that similar events in that area occur only once in every 2,000 to 10,000 years, on average. (2008-07-01)
Fatal mine collapse covered 50 acres
New calculations show that the deadly Crandall Canyon mine collapse - which registered as a magnitude-3.9 earthquake - began near where miners were excavating coal and quickly grew to a 50-acre cave-in, University of Utah seismologists say in a report on the tragedy. (2008-06-02)
Earthquake in Illinois could portend an emerging threat
To the surprise of many, the earthquake on April 18, 2008, about 120 miles east of St. Louis, originated in the Wabash Valley Fault and not the better-known and more-dreaded New Madrid Fault in Missouri's bootheel. (2008-04-25)
Dramatic developments at Kilauea Volcano: Scientists work to keep public safe and informed
Explosive eruptions and noxious gas emissions at Kilauea Volcano in Hawaii this week have prompted scientists to work around the clock to understand what will happen next and how to keep the public out of harm's way. (2008-03-28)
Earthquake 'memory' could spur aftershocks
Using a novel device that simulates earthquakes in a laboratory setting, a Los Alamos researcher and his colleagues have shown that seismic waves-the sounds radiated from earthquakes-can induce earthquake aftershocks, often long after a quake has subsided. (2008-01-04)
Los Angeles enjoying 1,000 year seismic lull
The Los Angeles basin appears to be in a seismic "lull" characterized by relatively smaller and infrequent earthquakes, according to a study in the September issue of Geology. (2007-08-24)
Real-Time Seismic Monitoring Station Installed Atop Active Underwater Volcano
This week, researchers will begin direct monitoring of the rumblings of a submarine volcano in the southeastern Caribbean Sea. (2007-05-11)
Major population centers may be at risk; building codes must reflect new seismic data
Earthquakes in stable continental regions lack sufficient understanding to prepare local populations for future seismic activity, according to a paper published in the February issue of the Bulletin of the Seismological Society of America (BSSA). (2007-02-08)
Listening in on the birth pangs of Earth's crust
Scientific business-as-usual became an adventure in ocean floor geol-ogy for Donald Forsyth, Alberto Saal and their students when the instruments they were sup-posed to retrieve for another scientist went missing. The researchers quickly collected samples and data that strongly suggested they had just missed a major episode of seafloor spreading - and the missing instruments had been buried in lava.

Scientists lose instruments, gain first look at seafloor formation
Ordinarily, losing almost all of one's instruments would be considered a severe setback to any scientist. But when Maya Tolstoy, a marine geophysicist at the Lamont-Doherty Earth Observatory, a member of the Earth Institute at Columbia University, recently learned that two-thirds of the seismometers she placed on the floor of the Pacific Ocean were trapped more than 8,000 feet (2500 meters) underwater, it turned out to be an extremely good sign.
