The so-called Abelian sandpile model has been studied by scientists for more than 30 years to better understand a physical phenomenon called self-organized criticality, which appears... more
Indonesia's Mount Merapi, one of the world's most active volcanoes, has spewed a plume of grey ash into the sky as fiery red molten lava streamed down from its crater. more
A new analysis has revealed that advanced satellite-based instrument capabilities are needed for global monitoring of microscopic particles, or aerosols, in the stratospheric layer of the atmosphere. Aerosols... more
In order to understand the global carbon cycle, deep-sea exploration is essential, an international team led by geologists from Innsbruck concludes. For the first time, they succeeded in quantifying the... more

Researchers have developed a new isotopic method to analyze the recent history of large stratospheric volcanic eruptions, using 2,600 years' worth of records contained in ice cores from Antarctica. Stratospheric eruptions can launch... more
Researchers have turned parts of a 13,000-mile-long testbed of 'dark fiber', unused fiber-optic cable, owned by the DOE Energy Sciences Network (ESnet), into a highly sensitive... more
In traditional seismology, researchers studying how the earth moves in the moments before, during, and after an earthquake rely on sensors that cost tens of thousands... more
For all their destructive power, most volcanic eruptions are local events. Lava flows tend to reach only a few miles at most, while airborne ash and soot travel a little farther. But... more
An eruption of one of Indonesia's most active volcanoes sent lava and searing gas clouds out the crater and made villagers leave the slopes, a volcanology official said Tuesday. more
Earthquakes happen when rocks on either side of a tectonic fault shift suddenly in opposite directions. Two main seismic waves that carry shaking out of a... more
A field trip to Namibia to study volcanic rocks led to an unexpected discovery by West Virginia University geologists Graham Andrews and Sarah Brown. more
Floating seismometers dubbed MERMAIDs -- Mobile Earthquake Recording in Marine Areas by Independent Divers -- reveal that Galápagos volcanoes are fed by a mantle plume reaching 1,900 km deep. By letting their... more
