Portions of Arctic coastline eroding, no end in sight (12/31/2009)

Portions of Arctic coastline eroding, no end in sightThe northern coastline of Alaska midway between Point Barrow and Prudhoe Bay is eroding by up to one-third the length of a football field annually because of a "triple whammy" of declining sea ice, warming seawater and increased wave activity, according to new study led by the University of Colorado at Boulder. ...> Full Article


Sun and moon trigger deep tremors on San Andreas Fault (12/29/2009)

Sun and moon trigger deep tremors on San Andreas FaultWhen the sun and moon are aligned with the San Andreas Fault they tug on it enough to increase the tremor rate deep underground, according to a new UC Berkeley study. While these tremors have not yet been linked to earthquakes, the tremors are associated with increased stress on the fault and may increase the risk of future quakes. The ease with which the deep rock slips indicates it is lubricated by high-pressure water. ...> Full Article

Pollution alters isolated thunderstorms (12/23/2009)

Pollution alters isolated thunderstormsNew research reveals how wind shear -- the same atmospheric conditions that cause bumpy airplane rides -- affects how pollution contributes to isolated thunderstorm clouds. The work improves scientists' understanding of how aerosols -- tiny unseen particles that make up pollution -- contribute to isolated thunderstorms and the climate cycle. How aerosols and clouds interact is one of the least understood aspects of climate, and this work allows researchers to better model clouds and precipitation. ...> Full Article

Pre-eruption earthquakes offer clues to volcano forecasters (12/21/2009)

Pre-eruption earthquakes offer clues to volcano forecastersLike an angry dog, a volcano growls before it bites, shaking the ground and getting "noisy" before erupting. This activity gives scientists an opportunity to study the tumult beneath a volcano and may help them improve the accuracy of eruption forecasts, according to UC Santa Cruz seismologist Emily Brodsky. ...> Full Article

Going vertical: Fleeing tsunamis by moving up, not out (12/19/2009)

Going vertical: Fleeing tsunamis by moving up, not outWhen the next big earthquake strikes Indonesia, a tsunami could follow close behind, killing thousands of people stuck in traffic jams while attempting to evacuate. Stanford researchers suggest lives can be saved if those residents take refuge instead in nearby tall buildings -- but only after those buildings are strengthened to withstand big waves. ...> Full Article

Black carbon deposits on Himalayan ice threaten Earth's 'Third Pole' (12/17/2009)

Black carbon deposits on Himalayan ice threaten Earth's 'Third Pole'Black soot deposited on Tibetan glaciers has contributed significantly to the retreat of the world's largest nonpolar ice masses, according to new research by scientists from NASA and the Chinese Academy of Sciences. Soot absorbs incoming solar radiation and can speed glacial melting when deposited on snow in sufficient quantities. ...> Full Article


Yellowstone's plumbing exposed (12/16/2009)

Yellowstone's plumbing exposedThe most detailed seismic images yet published of the Yellowstone supervolcano's plumbing shows a plume of hot and molten rock rising from the northwest at a depth of at least 410 miles, contradicting claims that there is no deep plume. A related University of Utah study indicates the banana-shaped magma chamber a few miles beneath Yellowstone is 20 percent larger than believed, so a future cataclysmic eruption could be larger than thought. ...> Full Article


Greenland glaciers: What lies beneath (12/16/2009)

Greenland glaciers:  What lies beneathScientists who study the melting of Greenland's glaciers are discovering that water flowing beneath the ice plays a much more complex role than they previously imagined. Researchers previously thought that meltwater simply lubricated ice against the bedrock, speeding the flow of glaciers out to sea. ...> Full Article

New study cites lower rate of quakes along some subduction zones (12/6/2009)

As the relative speed of the plates around a fault increases, is there a corresponding increase in the number of earthquakes produced along the fault? According to this study published in the December issue of BSSA, the answer depends upon the type of tectonic boundary. On certain types of boundary, the efficiency of earthquake production actually depends on the fault slip rate. ...> Full Article


Hawaiian hot spot has deep roots (12/5/2009)

Hawaiian hot spot has deep rootsA classic explanation for oceanic hot spots such as Hawaii has been that they originate from upwellings of hot rock, called mantle "plumes," deep in the Earth's mantle. Evidence for these deep structures has been sketchy, however. Now, a sophisticated array of seismometers deployed on the sea floor around Hawaii has provided the first high-resolution seismic images of a mantle plume extending to depths of at least 1,500 kilometers (932 miles). ...> Full Article


Strong regional climatic fluctuations in the tropics (12/4/2009)

Strong regional climatic fluctuations in the tropicsClimatic fluctuations close to the equator show a different pattern to climate change in the Arctic and Antarctic. In the tropics, distinct 11,500-year fluctuations between wet and dry periods can be clearly identified which do not occur in temperature reconstructions of polar ice cores. ...> Full Article
