    International research led by geologists from Curtin University has found that a volcanic province in the Indian Ocean was the world's most continuously active—erupting for 30 million years—fuelled by a constantly moving conveyor belt of magma. It's believed this magma conveyor belt, created by shifts in the seabed, continuously made space available for the molten rock to flow for millions of years, beginning around 120 million years ago. Research lead Qiang Jiang, a Ph.D. candidate from Curtin's School of Earth and Planetary Sciences, said the studied volcanoes were in the Kerguelen Plateau, located in the Indian Ocean, about 3,000 kilometers...

    An aerial flight over Yellowstone’s Midway Geyser Basin in 2004 shows Grand Prismatic Spring and Excelsior Geyser Crater, which drain into the nearby Firehole River. Courtesy of USGSIn the unlikely event of a volcanic supereruption at Yellowstone National Park, the northern Rocky Mountains would be blanketed in meters of ash, and millimeters would be deposited as far away as New York City, Los Angeles and Miami, according to a new study. An improved computer model developed by the study’s authors finds that the hypothetical, large eruption would create a distinctive kind of ash cloud known as an umbrella, which expands...

    Big Bangs: 'Stirring' Secrets Of Deadly Supervolcanoes UncoveredSupervolcanoes are orders of magnitude greater than any volcanic eruption in historic times. They are capable of causing long-lasting change to weather, threatening the extinction of species, and covering huge areas with lava and ash. (Credit: iStockphoto/Koch Valérie) ScienceDaily (May 30, 2008) — Researchers from McGill University and the University of British Columbia (UBC) have simulated in the lab the process that can turn ordinary volcanic eruptions into so-called “supervolcanoes,” with potentially devastating worldwide impact. The study was conducted by Dr. Ben Kennedy and and Dr. Mark Jellinek of UBC’s Department of Earth...

    SUPERVOLCANOES WARNING Slumbering supervolcanoes powerful enough to wipe out much of the planet may awaken much sooner than it had previously been thought. Experts believed it would take hundreds of thousands of years for reservoirs of molton rock, or magma, beneath a supervolcano to build for an eruption. But a new study indicates the time between super-eruptions can actually be tens of thousands of years - and many are already long overdue. A blast from a supervolcano would be strong enough cause mass extinction and change the world's climate. The findings, published in the Journal of Petrology, are bad...
