Life in the extreme
Cold seeps are deep-sea environments, usually a few square meters in size, where fluid is released through slow diffusion from the sea floor. Mud volcanoes which are active areas of fluid seepage, are other extreme environments discovered in the 1990s. These harsh conditions give rise to some of the most extreme and scientifically challenging... view more... (2006-11-09)
Study Compares Sound from Exploding Volcanoes with Jet Engines
New research on infrasound from volcanic eruptions shows an unexpected connection with jet engines. view more (2009-04-09)
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)
Venus Express reboots the search for active volcanoes on Venus
ESA's Venus Express has measured a highly variable quantity of the volcanic gas sulphur dioxide in the atmosphere of Venus. Scientists must now decide whether this is evidence for active volcanoes on Venus, or linked to a hitherto unknown mechanism affecting the upper atmosphere. view more (2008-04-07)
Martian Snow Source of Tropical Glaciers, Research Team Reports
Snow is the source of glacial deposits found at the base of the majestic volcanoes and mountains dotting the mid-latitude and tropical regions of Mars. view more (2006-01-20)
Hot volcanic eruptions could lead to a cooler Earth
Volcanic eruptions may be an agent of rapid and long-term climate change, according to new research by British scientists. view more (2005-06-13)
A Fresh Look Inside Mount St. Helens
Volcanoes are notoriously hard to study. All the action takes place deep inside, at enormous temperatures. So geophysicists make models, using what they know to develop theories about what they don't know. view more (2008-02-20)
Earth, Wind and Volcanoes - Disaster Science
Ash with Altitude "Volcanic ash, ejected into the stratosphere and spread horizontally by the winds, can cause serious damage to aircraft engines and sensors," says Dr Charles Sprinkle of the US National Weather Service. Modern jet engines operate at such high temperatures that volcanic ash ingested can melt, stick to the turbines and... view more... (1999-10-26)
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)
Off the shelf maps help mitigate volcanic hazards
When volcanoes erupt, pinpointing the regions at high risk for lethal hazards and deciding whether or not to evacuate a resistant population comprise the most difficult problems faced by hazards managers. Now a team of volcanologists has a program that maps potential problem areas quickly, taking much of the guesswork out of decision making and... view more... (2009-01-22)
Discovered: World's Largest Tsunami Debris
A line of massive boulders on the western shore of Tonga may be evidence of the most powerful volcano-triggered tsunami found to date. Up to 9 meters (30 feet) high and weighing up to 1.6 million kilograms (3.5 million pounds), the seven coral boulders are located 100 to 400 meters (300 to 1,300 feet) from the coast. view more (2008-09-26)
Volcanoes played pivotal role in ancient ice age, mass extinction
Researchers here have discovered the pivotal role that volcanoes played in a deadly ice age 450 million years ago. Perhaps ironically, these volcanoes first caused global warming -- by releasing massive amounts of carbon dioxide into the atmosphere. When they stopped erupting, Earth's climate was thrown off balance, and the ice age began. view more (2009-10-27)
Earthquake swarms not just clustered around volcanoes, geothermal regions
An earthquake swarm - a steady drumbeat of moderate, related seismic events - over hours or days, often can be observed near a volcano such as Mount St. Helens in Washington state or in a geothermal region such as Yellowstone National Park in Wyoming. view more (2006-10-26)
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)
Real-Time Seismic Monitoring Station Installed Atop Active Underwater Volcano
This week, researchers will begin direct monitoring of the rumblings of a submarine volcano in the southeastern Caribbean Sea. view more (2007-05-11)
Joining forces to predict tsunamis: Pan-European approach to disaster prevention
Following a series of well documented natural disasters with grave human and economic consequences, the ability to predict these devastating events has once more come to the fore as a research priority for the European scientific community. view more (2006-11-07)
Short-circuit found in ocean circulation
Scientists have discovered how ocean circulation is working in the current that flows around Antarctica by tracing the path of helium from underwater volcanoes. The details are published in Nature this week. view more (2007-05-11)
U of Minnesota-led study reveals mysteries of deep-sea nutrients
Iron dust, the rare but necessary nutrient for most life, can not only be washed into the ocean from rivers or blown out to sea, but it can bubble up from the depths of the ocean floor, a new study led by a University of Minnesota scientist shows. view more (2009-02-09)
Better living through chemistry
Scientists have completed the first study of microbes that live within the plumbing of deep-sea mud volcanoes in the Gulf of Mexico, where conditions may resemble those in extraterrestrial environments and early Earth. view more (2009-04-08)
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)
