Rare volcanic plumes create uncommonly dangerous ash flows
Three unique photographs of a recent volcanic eruption in a remote part of Ecuador show a plume unlike any previously documented, and hint at a newly recognized hazard.   view more (2006-03-15)

U of M to help NASA 'follow the sun' — in stereo
Like geologists poring over seismograph records to identify the telltale signature of an imminent earthquake, University of Minnesota researchers are poised to probe the sun for a tipoff that a huge eruption of its corona is brewing.   view more (2006-10-19)

New research puts 'killer La Palma tsunami' at distant future
The volcanic island of La Palma in the Canaries is much more stable than is generally assumed, Dutch scientists working at the TU Delft have found.   view more (2006-09-21)

CU-Boulder team discovers first ancient manioc fields in Americas
A University of Colorado at Boulder team excavating an ancient Maya village in El Salvador buried by a volcanic eruption 1,400 years ago has discovered an ancient field of manioc, the first evidence for cultivation of the calorie-rich tuber in the New World.   view more (2007-08-21)

1843 stellar eruption may be new type of star explosion
Eta Carinae, the galaxy's biggest, brightest and perhaps most studied star after the sun, has been keeping a secret: Its giant outbursts appear to be driven by an entirely new type of stellar explosion that is fainter than a typical supernova and does not destroy the star.   view more (2008-09-11)

Mega Eruption of Yellowstone's Southern Twin
North America isn't the only continent that's experienced super-colossal volcanic eruptions in the recent geologic past.   view more (2006-03-29)

Stratospheric injections could help cool Earth, computer model shows
A two-pronged approach to stabilizing climate, with cuts in greenhouse gas emissions as well as injections of climate-cooling sulfates, could prove more effective than either approach used separately.   view more (2006-09-15)

Aurorae and Volcanic Eruptions
Impressive thermal-infrared images have been obtained of the giant planet Jupiter during tests of a new detector in the ISAAC instrument on the ESO Very Large Telescope (VLT) at the Paranal Observatory (Chile). They show in particular the full extent of the northern auroral ring and part of the... view more (2001-06-07)

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)

Volcanoes, asteroids and mass extinctions
Neither massive volcanic eruptions nor extraterrestrial impacts are sufficiently powerful on their own to cause mass extinctions of life on Earth, research by University of Leicester geologists suggests. Instead, both events coincidentally occurring together may be required to cause the worst mass... view more (2004-05-17)

Historic volcanic eruption shrunk the mighty Nile River
Volcanic eruptions in high latitudes can greatly alter climate and distant river flows, including the Nile, according to a recent study funded in part by NASA.   view more (2006-11-22)

No safe ground for life to stand on during world's largest mass extinction
The world's largest mass extinction was probably caused by poisonous volcanic gas, according to research published today.   view more (2005-12-02)

Volcanoes helped slow ocean warming trend, researchers find
Ocean temperatures might have risen even higher during the last century if it weren't for volcanoes that spewed ashes and aerosols into the upper atmosphere, researchers have found. The eruptions also offset a large percentage of sea level rise caused by human activity.   view more (2006-02-10)

Scientist proposes explanation for puzzling property of night-shining clouds at the edge of space
An explanation for a strange property of noctilucent clouds--thin, wispy clouds hovering at the edge of space at 85 km altitude--has been proposed by an experimental plasma physicist at the California Institute of Technology (Caltech), possibly laying to rest a decades-long mystery.   view more (2008-09-26)

Supernova Imposter Goes Supernova
In a galaxy far, far away, a massive star suffered a nasty double whammy. On Oct. 20, 2004, Japanese amateur astronomer Koichi Itagaki saw the star let loose an outburst so bright that it was initially mistaken for a supernova. The star survived, but for only two years. On Oct. 11, 2006,... view more (2007-04-05)

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)

NASA data show earthquakes may quickly boost regional volcanoes
Scientists using NASA satellite data have found strong evidence that a major earthquake can lead to a nearly immediate increase in regional volcanic activity.   view more (2007-04-11)

Methane Eruptions On The Sea Floor - Science article: New evidence, new methods
Methane is a highly potent greenhouse gas. In its solid, ice form, called methane hydrate, it is stored in large amounts below the sea floor. Some signs indicate that there have been repeated intense undersea methane emissions over the course of the Earth's history. Often, these emissions appeared... view more (2003-02-19)

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)

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... view more (2008-09-26)

Venus mission will hold surprises says U. of Colorado planetary scientist
University of Colorado at Boulder planetary scientist Larry Esposito, a member of the European Space Agency's Venus Express science team, believes the upcoming mission to Earth's "evil twin" planet should be full of surprises.   view more (2005-11-03)

Watching rocks grow: Theory explains landscape of geothermal springs
Scientists at the University of Illinois at Urbana-Champaign have successfully modeled the spectacular landscapes seen at geothermal hot springs.   view more (2006-07-06)

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)

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)

EARLY HOMINOIDS MAY HAVE SUFFERED DEATH BY VOLCANO
Geological re-evaluation of deposits in which fossils of the human precursor Proconsul have long been found suggests that they lived in a semi-arid environment close to a then-active volcano (Kisingiri). Moreover the abundant hominoid fossils may represent "death assemblages" - whole populations... view more (1999-04-28)
