An unusual signal detected by the seismic monitoring station at the Smithsonian Tropical Research Institute's research facility on Barro Colorado Island results from waves in Lake Gatun, the reservoir that forms the Panama Canal channel, scientists report. Understanding seismic background signals leads to improved earthquake and tsunami detection in the Caribbean region where 100 tsunamis have been reported in the past 500 years.As part of a $37.5 million U.S. presidential initiative to...

First such station installed northwest of Columbia, Mississippi Most seismic activity--and earthquakes--have been in the U.S. West. But the East is not out of the woods in terms of risk, geologists say. After a six-year march eastward from the U.S. West Coast, the EarthScope Transportable Array seismic network has reached a major milestone: installation of the first Transportable Array station east of the Mississippi River. Station 345A, located on a private farm about 15 miles northwest of...

Learning from history, TAU invention can improve earthquake prediction today Earthquakes are one of the world's biggest enigmas "” impossible to predict and able to wreak untold damage within seconds. Now, a new tool from Tel Aviv University may be able to learn from earthquakes of the ancient past to better predict earthquakes of the future. Prof. Shmuel Marco of Tel Aviv University's Department of Geophysics and Planetary Sciences in the Raymond and Beverly Sackler Faculty of Exact...

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. The observation provides an additional support that seismic waves from distant earthquakes could also trigger seismic events on the other side of the earth. The results may be found online in the journal Geophysical Research...

By Tony Fitzpatrick, Washington University in St. Louis Careful analysis shows seismometer noise includes signals from storms in the South Atlantic and 'footquakes' from soccer matches. If you wander up to a seismograph in a museum, unless you are lucky enough to be there right during an earthquake, all you will see is a small wiggly signal being recorded. What's inside the wiggles is called noise by seismologists, because the signal is always there and originates from the normal activity of...

ARMONK, N.Y., Oct. 22 /PRNewswire/ -- IBM (NYSE: IBM) inventors have developed a patented natural disaster warning system, which uses analytics to improve the effectiveness and timeliness of post-event rescue efforts in cities and other locations where efficient emergency response is essential following a natural disaster. It also offers a means to accurately predict the location and timing of subsequent catastrophic events, which will further aid evacuation efforts. (Logo:...

A Princeton University-led research team has developed the capability to produce realistic movies of earthquakes based on complex computer simulations that can be made available worldwide within hours of a disastrous upheaval. The videos show waves of ground motion spreading out from an epicenter. In making them widely available, the team of computational seismologists and computer scientists aims to aid researchers working to improve understanding of earthquakes and develop better maps of...

Scientists study the February Chilean earthquake, and the likelihood of future such quakes In response to the magnitude 8.8 earthquake that occurred in Chile on February 27, 2010, the National Science Foundation (NSF) has awarded three major Rapid Response Research (RAPID) grants to study how the quake happened, and learn from those findings for the future. The Chile quake is the fifth largest earthquake ever recorded, and the second largest that has occurred since a modern suite of...

Seismologists have found a new way to piece together the history of hurricanes in the North Atlantic - by looking back through records of the planet's seismic noise. It's an entirely new way to tap into the rich trove of seismic records, and the strategy might help establish a link between global warming and the frequency or intensity of hurricanes. "Looking for something like hurricane records in seismology doesn't occur to anybody," said Carl Ebeling, of Northwestern University in Evanston....

Long-term monitoring by Stony Brook University researchers finds rip currents are frequent but short-lived at East Hampton Village Beach Rip currents"”powerful, channeled currents of water flowing away from the shore"”represent a danger to human life and property. Rip currents are responsible for more than one hundred deaths on our nation's beaches each year, according to the United States Lifesaving Association, and if rip currents persist long enough they can cause beach...

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...
