April Flowers for redOrbit.com - Your Universe Online A new, detailed image of the volcanic plumbing beneath Mt. Rainier has been created by a group of researchers from the University of Utah, Woods Hole Oceanographic Institution, the College of New Jersey and the University of Bergen, Norway. The study, published in Nature, measured how fast the Earth conducts electricity and seismic waves. "This is the most direct image yet capturing the melting process that feeds magma into a crustal...

Large Magma Chamber Sits Below World’s Most Active Volcano
2014-01-29 13:29:50

[ Watch the Video: What's Bubbling Below The Kilauea Volcano? ] Lee Rannals for redOrbit.com - Your Universe Online University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science researchers have discovered a large magma chamber below the world’s most active volcano. The new discovery is the first geophysical observation that large magma chambers exist in the deeper parts of Kilauea. For the study, the team analyzed the seismic waves that travel through the volcano....

Supervolcanoes And Volcanic Activity
2014-01-06 03:54:43

redOrbit Staff & Wire Reports - Your Universe Online One team of researchers has uncovered the factors that determine the frequency and magnitude of volcanic activity, while another has identified the triggers for the rare and explosive eruptions experienced by supervolcanoes, according to studies currently appearing in the advanced online edition of the journal Nature Geoscience. In one paper, ETH-Zurich professor Carmen Sanchez-Valle and her colleagues used an X-ray beam at the...

Improved Eruption Forecasts May Come Via Costa Rican Volcano Study
2013-08-01 07:54:55

April Flowers for redOrbit.com - Your Universe Online Compared to the geologic timescales most volcanoes operate on, Costa Rica's Irazu has something of a short fuse. A new study, led by Columbia University's Lamont-Doherty Earth Observatory, suggests the 1960's eruption of Costa Rica's largest stratovolcano was triggered by magma rising from the mantle over a few short months, rather than thousands of years or more, as many scientists have thought. The study, published in Nature, is...

Trigger For Explosive Volcanic Eruptions Identified
2012-10-13 09:27:11

Lee Rannals for redOrbit.com — Your Universe Online Scientists have identified a trigger for the largest explosive volcanic eruptions on Earth, according to a report published in the journal Scientific Reports. University of Southampton researchers investigated crystal cumulate nodules and their trapped magma to see what caused eruptions at the Las Cañadas volcanic caldera on Tenerife, in the Canary Islands. This volcano has generated at least eight major...

Georgia Tech instruments measure unprecedented deformation Do a Google image search for “Greece.” Before you find pictures of the Parthenon or Acropolis, you´ll see several beautiful photos of Santorini, the picturesque island in the Aegean Sea. The British Broadcasting Company named it the world´s best island in 2011. Santorini is a tourist magnet, famous for its breathtaking, cliff side views and sunsets. It´s also a volcanic island that has been relatively...

The Soufriere Hills Volcano on Montserrat erupted in 1995, and an international team of researchers has studied this volcano from land and sea since then to understand the workings of andesite volcanos more completely. "To the extent that the Soufriere Hills Volcano is typical of andesitic dome building volcanoes, results from this research can be expected to apply more generally," said Barry Voight, professor emeritus of geosciences, Penn State. Voight and R. S. J. Sparks, the Channing Wills...

A prominent vulcanologist said on Monday that Europe's largest undersea volcano could disintegrate and unleash a tsunami that would engulf southern Italy "at any time." Enzo Boschi told the Corriere della Sera daily that the Marsili volcano, which is bursting with magma, has "fragile walls" that could collapse. "It could even happen tomorrow," said Boschi, president of the National Institute of Geophysics and Volcanology (INGV). "Our latest research shows that the volcano is not...

Researchers from The University of British Columbia and McGill University have simulated in the lab the process that can turn ordinary volcanic eruptions into so-called "supervolcanoes." The study was conducted by Ben Kennedy and Mark Jellinek of UBC's Dept. of Earth and Ocean Sciences, and John Stix of McGill's Dept. of Earth and Planetary Sciences. Their results are published this week in the journal Nature Geoscience. Supervolcanoes are orders of magnitude greater than any volcanic...

WASHINGTON (AP) - Yellowstone National Park, once the site of a giant volcano, has begun swelling up, possibly because molten rock is accumulating beneath the surface, scientists report. But, "there is no evidence of an imminent volcanic eruption," said Robert B. Smith, a professor of geophysics at the University of Utah. Many giant volcanic craters around the world go up and down over decades without erupting, he said. Smith and colleagues report in Friday's issue of the journal Science that...
