'Rosetta Stone' of supervolcanoes discovered in Italian Alps
Scientists have found the "Rosetta Stone" of supervolcanoes, those giant pockmarks in the Earth's surface produced by rare and massive explosive eruptions that rank among nature's most violent events. The eruptions produce devastation on a regional scale - and possibly trigger climatic and environmental effects at a global scale. view more (2009-09-21)
CU-Boulder tracks movements of ancient Central Americans using satellites, video-game technology
Satellite imagery meshed with video-game technology is allowing University of Colorado at Boulder and NASA researchers to virtually "fly" along footpaths used by Central Americans 2,000 years ago on spiritual pilgrimages to ancestral cemeteries. view more (2007-01-04)
New, hands-on science demos teach young students how volcanoes 'blow their tops,' spew lava
A popular volcano demonstration in grade school science class rivets students' attention as it spews bubbly liquid over a tabletop, but it comes up short in explaining all the ways that volcanoes form and evolve. view more (2006-10-25)
At Least Part of Climate Change is Man-Made
Humanity does seem to have been a major contributor to global warming after all. This has been demonstrated by new simulations carried out at the University of Bonn. The Bonn meteorologists used about 30 different models to investigate how the Earth's average annual temperature would have developed with and without the influence of climate gases.... view more...

Geologists reveal secrets behind supervolcano eruption
Researchers at Rensselaer Polytechnic Institute have discovered what likely triggered the eruption of a "supervolcano" that coated much of the western half of the United States with ash fallout 760,000 years ago. view more (2007-03-06)
Marine scientists return from expedition to erupting undersea volcano
Scientists who have just returned from an expedition to an erupting undersea volcano near the Island of Guam report that the volcano appears to be continuously active, has grown considerably in size during the past three years, and its activity supports a unique biological community thriving despite the eruptions. view more (2009-05-06)
Meteor no longer prime suspect in great extinction
The greatest mass extinction in Earth's history also may have been one of the slowest, according to a study that casts further doubt on the extinction-by-meteor theory. view more (2007-10-25)
Dinosaur Deaths Outsourced to India?
A series of monumental volcanic eruptions in India may have killed the dinosaurs 65 million years ago, not a meteor impact in the Gulf of Mexico. view more (2007-10-31)
Scientist Anticipates Major Eruption of Peru`s El Misti Volcano
Boulder, Colo.- Scientist Jean-Claude Thouret is worried about the one million people who live in the suburbs and city of Arequipa in southern Peru. The city`s center is only 17 km from the summit of the active El Misti volcano. Thouret and his colleagues report new findings on El Misti`s geology, past eruptions, and the reasons for probable... view more... (2001-12-10)
More than a meteor likely killed dinosaurs 65 million years ago
Growing evidence shows that the dinosaurs and their contemporaries were not wiped out by the famed Chicxulub meteor impact alone, according to a paleontologist who says multiple meteor impacts, massive volcanism in India and climate changes culminated in the end of the Cretaceous Period. view more (2006-10-27)
Geologist plans volcano safety for Ecuadorians
A geologist at Washington University in St. Louis is doing his part to make sure that the small Latin American country of Ecuador follows the Boy Scout motto: Be prepared. view more (2007-08-22)
Natural climate change may be larger than commonly thought
A new study of climate in the Northern Hemisphere for the past 2000 years shows that natural climate change may be larger than generally thought. This is displayed in results from scientists at the Stockholm University, made in cooperation with Russian scientists, which are published in Nature on 10 Feb 2005. view more (2005-02-09)
Climate models consistent with ocean warming observations
Climate models are reliable tools that help researchers better understand the observed record of ocean warming and variability. view more (2007-06-19)
Sulfur signature changes thoughts on atmospheric oxygen
Ancient sediments that once resided on a lake bed and the ocean floor show sulfur isotope ratios unlike those found in other samples from the same time, calling into question accepted ideas about when the Earth's atmosphere began to contain oxygen. view more (2006-08-24)
Volcanic plumbing dictates development of deep-sea hydrothermal vents
After years of results that repeatedly dogged him, University of Oregon geologist Douglas R. Toomey decided to follow the trail of data surfacing from the Pacific Ocean. In doing so, he and his collaborators may have altered long-held assumptions involving plate tectonics on the ocean floor. view more (2007-03-22)
New Pompeii before Pompeii discovered
Swedish archeologists have found previously unknown prehistoric settlements under ancient Pompeii. The Swedish Pompeii Project, tied to Stockholm University and the Swedish Institute in Rome, has worked for five seasons in a section of Pompeii to study and document the relics of the ancient city. When a well was emptied of its contents of pumice... view more... (2005-04-18)
New theory sheds light on space enigma
An enormous plume of dust and water spurts violently into space from the south pole of Enceladus, Saturn's sixth-largest moon. This raging eruption has intrigued scientists ever since the Cassini spacecraft provided dramatic images of the phenomenon. view more (2008-02-25)
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)
New CIESM Monograph
Human records of recent geological evolution in the Mediterranean Basin-historical and archaeological evidence. This is one of the most ambitious volumes produced yet in the young -- and already sizeable - CIESM Workshop Monograph collection. This 152 page- report, edited by Jean Mascle and Frederic Briand, is rich in thoughts, analyses,... view more... (2004-05-26)
Icelandic volcano caused historic famine in Egypt, says Rutgers-based team
An environmental drama played out on the world stage in the late 18th century when a volcano killed 9,000 Icelanders and brought a famine to Egypt that reduced the population of the Nile valley by a sixth. view more (2006-11-22)
