Latest Supervolcano Stories
Seismologists from the University of Utah have discovered a massive pool of hot, partly molten rock hidden deep beneath Yellowstone’s supervolcano – a reservoir that is more than four times larger than the shallower, more well-known magma chamber there.
As one might expect, Yellowstone National Park’s hot springs, geysers and other hydrothermal vents release gases stored deep below the Earth, including carbon dioxide and methane. Another gas has also been discovered to be squeaking out of Yellowstone’s vents.
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.
A supervolcano located in Yellowstone National Park is much larger than previously thought, according to research presented at the American Geophysical Union last week.
Geologists from Brigham Young University in Utah have found evidence of a massive supervolcano near the Utah-Nevada border that had a massive eruption around 30 million years ago. It was 5,000 times larger than the Mount St. Helens eruption in 1980.
Studies of zircon in Yellowstone rocks are giving scientists a whole new look at the life cycle of supervolcanoes.
New research has taken a closer look at how ash produced from supervolcanoes can turn back into lava once it falls back to Earth.
Each of the six new papers published in Geosphere on 13 June address geoscience compiled in specially themed issues: CRevolution 2: Origin and Evolution of the Colorado River System II; The 36–18 Ma southern Great Basin, USA, ignimbrite province and flareup: Swarms of subduction-related supervolcanoes; New Developments in Grenville Geology; and Origin and Evolution of the Sierra Nevada and Walker Lane.
Popular theory suggests that a massive asteroid smashed into Earth around 65 million years ago wiping most life, including the dinosaurs, off the face of the earth. But scientists have found evidence of another planetary cataclysm that occurred some 135 million years before the Cretaceous-Paleogene Extinction (CPE) event.
New research suggests that eruptions at some of Earth's largest volcanoes could be predicted decades before the event actually occurs, potentially making it easier for experts to monitor danger zones and conduct pre-emptive evacuations to keep residents out of harm's way.
Lake Toba, also known as Toba, is a supervolcano and lake that is located in Indonesia on the island of Sumatra. The volcano reaches an elevation of 2,953 feet and the lake stretches across an area of sixty-two miles and is the largest volcanic lake on earth. Toba holds a caldera complex that is comprised of four volcanic craters that overlap each other, the youngest of which is noted as the largest Quaternary caldera. Visible features within the lake include three craters, four cones, and...
