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...

Japan's recent magnitude 9.0 earthquake, which triggered a devastating tsunami, relieved stress along part of the quake fault but also has contributed to the buildup of stress in other areas, putting some of the country at risk for up to years of sizeable aftershocks and perhaps new main shocks, scientists say. After studying data from Japan's extensive seismic network, researchers from the Woods Hole Oceanographic Institution (WHOI), Kyoto University and the U.S. Geological Survey (USGS)...

By Louis Bergeron, Stanford The magnitude 9 earthquake and resulting tsunami that struck Japan on March 11 were like a one-two punch "“ first violently shaking, then swamping the islands "“ causing tens of thousands of deaths and hundreds of billions of dollars in damage. Now Stanford researchers have discovered the catastrophe was caused by a sequence of unusual geologic events never before seen so clearly. "It was not appreciated before this earthquake that this size of...

VANCOUVER, May 19 /PRNewswire/ - Kimber Resources Inc. (NYSE Amex:KBX) (TSX:KBR) is pleased to announce the results of a further 9 drill holes from its ongoing drill program at the Carmen Deposit at its Monterde Project in Mexico.  Five of the drill holes (MTR-480, 481, 482, 490 and 491) were drilled to upgrade the confidence level of shallow mineral resources potentially amenable to open pit extraction ("Carmen Pit" targets), while the remaining holes were drilled with the...

Bolivia may need to prepare for a possible 8.9 magnitude quake that would be 125 times more powerful than previously calculated to be possible in this area, AFP reports. Two million people in the region of the east of the central Andes mountains could be affected in what had been thought, until now, to be a relatively calm area for seismic activity, according to a study published in Nature Geoscience. "No one suspected that the previous estimates were too low," Benjamin Brooks, a...

TACOMA, Wash., April 25, 2011 /PRNewswire/ -- When the next major earthquake hits this region, a substantial amount of buildings and schools are likely to sustain major damage and, in many cases, even collapse. But thanks to a new line of desks that serve as protective armor, a lot of the folks inside these buildings are now more likely to survive. - Robert von Bereghy, founder of LifeGuard Structures, WHO: maker of new earthquake-proof desks and...

The massive subduction zone earthquake in Japan caused a significant level of soil "liquefaction" that has surprised researchers with its widespread severity, a new analysis shows. The findings also raise questions about whether existing building codes and engineering technologies are adequately accounting for this phenomenon in other vulnerable locations, which in the U.S. include Portland, Ore., parts of the Willamette Valley and other areas of Oregon, Washington and California. A...

The U.S. Geological Survey said that a 6.6-magnitude earthquake struck in the South Pacific on Monday. The survey said that the epicenter was south of the Kermadeic Islands, about 340 miles east-northeast of Auckland, New Zealand. The earthquake had a preliminary magnitude of 6.4, but the U.S. Geological Survey later increased to a 6.6-magnitude quake. The Pacific Tsunami Warning Center said that it does not expect the earthquake to generate "a destructive, Pacific-wide tsunami." A...

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...
