Volcano-like tremors detected deep within Earth's crust near San Andreas
Tremors within the Earth are usually-but not always-related to the activity of a volcano. Now, such vibrations have been recorded nowhere near a volcano, but at a geologic observatory at the San Andreas Fault.   view more (2006-04-13)

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)

Warmer means windier on world's biggest lake
Rising water temperatures are kicking up more powerful winds on Lake Superior, with consequences for currents, biological cycles, pollution and more on the world's largest lake and its smaller brethren.   view more (2009-11-16)

Slowly slip-sliding faults don't cause earthquakes
Some slow-moving faults may help protect some regions of Italy and other parts of the world against destructive earthquakes, suggests new research from The University of Arizona in Tucson.   view more (2009-08-28)

Yellowstone's quiet power
A 17-year University of Utah study of ground movements shows that the power of the huge volcanic hotspot beneath Yellowstone National Park is much greater than previously thought during times when the giant volcano is slumbering.   view more (2007-03-01)

Recipe for a storm: The ingredients for more powerful Atlantic hurricanes
As the world warms, the interaction between the Atlantic Ocean and atmosphere may be the recipe for stronger, more frequent hurricanes.   view more (2007-11-30)

Geologists push back date basins formed, supporting frozen Earth theory
Even in geology, it's not often a date gets revised by 500 million years. But University of Florida geologists say they have found strong evidence that a half-dozen major basins in India were formed a billion or more years ago, making them at least 500 million years older than commonly thought.   view more (2008-07-07)

Geologists point to outer space as source of the Earth's mineral riches
According to a new study by geologists at the University of Toronto and the University of Maryland, the wealth of some minerals that lie in the rock beneath the Earth's surface may be extraterrestrial in origin.   view more (2009-10-19)

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 -... view more... (2006-11-27)

Climate gas could disrupt food chain
Levels of a climate cooling gas will change as carbon dioxide increases, affecting food webs along the way, said Dr Michael Steinke at a Science Media Centre press briefing today.   view more (2007-12-11)

New Test of Snow's Thickness May 'Bear' Results Key to Polar Climate Studies, Wildlife Habitat
A NASA-funded expedition to the Arctic to map the thickness of snow has a legion of unexpected furry fans hailing from one of the world's coldest regions: polar bears.   view more (2006-03-16)

NASA satellite reveals a depressed and disorganized Henri
Depression happens to everyone, even tropical storms, and Henri is now tropically depressed. NASA satellite imagery has confirmed he's weakened to a tropical depression and he is further expected to degenerate into a remnant low pressure area.   view more (2009-10-09)

News from Earth's magnetic field
It is widely known that the geomagnetic field shields our planet against highly energetic cosmic particles. The importance of the magnetic field for answering geological, tectonic or even archaeological questions is less known.   view more (2007-12-21)

Long-term ocean data confirm fishing puts species in 'double jeopardy'
For the first time, research has shown that fishing can promote boom and bust swings in supplies of targeted fish stocks.   view more (2006-10-19)

Ancient raindrops reveal the origins of California's Sierra Nevada range
One of the longest ongoing controversies in Earth science concerns the age of California's Sierra Nevada, the tallest mountain range in the continental United States and site of Yosemite National Park, Lake Tahoe and other scenic wonders.   view more (2006-07-07)

Report Warns about Carbon Dioxide Threats to Marine Life
Worldwide emissions of carbon dioxide from fossil fuel burning are dramatically altering ocean chemistry and threatening marine organisms, including corals, that secrete skeletal structures and support oceanic biodiversity.   view more (2006-07-06)

Study of islands reveals surprising extinction results
It's no secret that humans are having a huge impact on the life cycles of plants and animals. UC Santa Barbara's Steven D. Gaines and fellow researcher Dov Sax decided to test that theory by studying the world's far-flung islands.   view more (2008-08-27)

Persistent Man-made Chemical Pollutants Found in Deep-sea Octopods and Squids
New evidence that chemical contaminants are finding their way into the deep-sea food web has been found in deep-sea squids and octopods, including the strange-looking "vampire squid". These species are food for deep-diving toothed whales and other predators.   view more (2008-06-10)

Surface features on Titan form like Earth's, but with a frigid twist
"It is really surprising how closely Titan's surface resembles Earth's," says Rosaly Lopes, a planetary geologist at the Jet Propulsion Laboratory (JPL) in Pasadena, California, who is presenting the results on Friday, 7 August.   view more (2009-08-07)

Time to lift the geoengineering taboo
Hot on the heels of the Royal Society's Geoengineering the Climate report, September's Physics World contains feature comment from UK experts stressing the need to start taking geoengineering - deliberate interventions in the climate system to counteract man-made global warming - more seriously.   view more (2009-09-01)
