A sea change for earthquakes
A reconstruction of land movements and changes in sea levels for three massive historic earthquakes in Alaska gives clues that may help scientists forecast future earthquakes and earthquake-triggered tsunami. To be published in this week's Journal of Quaternary Science¹ the findings should help reduce losses from future catastrophic events. view more (2005-02-21)
University of Nevada scientists gauge earthquake hazards through study of precariously balance rocks
A seismological research team from the University of Nevada, Reno is finding ways to make precariously balanced rocks talk. In so doing, they are unlocking valuable scientific information in assessing seismic hazards in areas throughout the West. view more (2007-03-01)
New NIST publication series addresses design of earthquake-resistant structures
Where can you find some of the latest insights in designing earthquake-resistant buildings joined together with current information on building codes? view more (2008-09-05)
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. view more (2008-01-04)
Atoms under the mantle
At a depth of 2900 kilometres, the layer between the Earth's mantle and its core has always intrigued geophysicists because they are unable to explain the seismic data it generates. view more (2007-03-07)
Predicted ground motions for great earthquake in Pacific Northwest: Seattle, Victoria and Vancouver
A new study evaluates expected ground motion in Seattle, Victoria and Vancouver from earthquakes of magnitude 7.5 - 9.0, providing engineers and policymakers with a new tool to build or retrofit structures to withstand seismic waves from large "subduction" earthquakes off the continent's west coast. view more (2009-06-11)
Media invitation: Nuclear test ban spurs research into UK`s rocky foundations
The vital role UK earth scientist play in monitoring the Comprehensive Nuclear Test Ban Treaty (CTBT), and how their research is leading to a greater understanding of what the Earth is like under the British Isles, is the subject of a two-day meeting in London on the 7th and 8th of February. Sponsored by the Royal Astronomical Society and the... view more... (2002-02-03)
Earth's core rotates faster than its crust, scientists say
Scientists have ended a 9-year-old debate by proving that Earth's core rotates faster than its surface, by about 0.3 to 0.5 degree per year. view more (2005-08-26)
Unique study shows oil, gas seismic work not affecting Gulf sperm whales
Noise can be irritating and possibly harmful for everything from mice to humans - and maybe even 60-foot whales in the Gulf of Mexico. view more (2008-08-22)
Underground Nuclear Explosions Deteriorate The Ozone Layer
Russian scientists have found one more cause of depletion of the ozone layer. They think that abyssal gases can go to the surface and reach stratosphere, deteriorating the ozone shield. Underground nuclear explosions enforce this process. A geologist Boris Golubov of the Institute of Geosphere Dynamics RAS and a climatologist Grigoriy Kruchenitsky... view more... (2002-08-16)
Amadeus and Esmeraldas: two marine geophysics campaigns to investigate strong earthquakes off Ecuador and Colombia
Several large earthquakes with magnitude higher than 8 on the Richter scale have already occurred along the margins between the Nazca and South American tectonic plates, under the ocean off Ecuador and Colombia. This region is vulnerable, all the more so because since the 1980s, Ecuador's oil export terminal is sited within it. More information is... view more... (2005-02-16)
Seismic response to natural gas anomalies in crystalline rocks
The research done at the Chinese Academy of Geological Sciences has shown that after geochemical experiments, the porosity of crystalline rocks in the middle crust increases sharply due to water-rock interaction. view more (2008-11-05)
Acoustic noise contains valuable information
The proper processing of acoustic noise can provide a wealth of information. Geophysicists have used seismic background noise measurements to reconstruct the crustal structure under Southern California. view more (2006-12-08)
Listening to rocks helps researchers better understand earthquakes
When Apollo punished King Midas by giving him donkey ears, only the king and his barber knew. Unable to keep a secret, the barber dug a hole, whispered into it, "King Midas has donkey ears," and filled the hole. But plants sprouted from the hole, and with each passing breeze, shared the king's secret. view more (2009-08-18)
San Andreas affected by 2004 Sumatran quake
U.S. seismologists have found evidence that the massive 2004 earthquake that triggered killer tsunamis throughout the Indian Ocean weakened at least a portion of California's famed San Andreas Fault. view more (2009-10-01)
Scientists use seismic waves to locate missing rock under Tibet
Geologists at the University of Illinois at Urbana-Champaign have located a huge chunk of Earth's lithosphere that went missing 15 million years ago. By finding the massive block of errant rock beneath Tibet, the researchers are helping solve a long-standing mystery, and clarifying how continents behave when they collide. view more (2007-02-08)
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. view more (2008-03-28)
U of M researchers unlock mystery of layer encircling the Earth's core
University of Minnesota associate professor of chemical engineering Renata Wentzcovitch and her team of researchers have confirmed the properties of a mineral (post-perovskite) that may form near the Earth's core in a layer called the D'' region. view more (2006-01-31)
Ground movement risks identified by Terrafirma
Ground movements are responsible for hundreds of deaths and billions of Euros annually, and the threat they pose is increasing due to urbanisation and land use. ESA's GMES Service Element Programme is backing a project, Terrafirma, to help mitigate these risks. view more (2006-09-11)
African initiative trains students, explores geophysical mysteries
Earthquakes, volcanoes and the African superplume are only some of the phenomena under investigation through AfricaArray, a program that establishes geophysical observatories, trains African and American students and examines geophysical phenomena on the African continent. view more (2009-02-13)
