Two Sources Of Helium Produced By Ancient Yellowstone Activity
2014-02-20 07:33:51

[ Watch the Video: Yellowstone Releasing Ancient Helium ] Lawrence LeBlond for redOrbit.com - Your Universe Online 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, and while it is a common gas released from volcanic rocks, in this region, most of it comes from a much...

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...

YellowStone's Volcanic Caldera Much More Super Than Estimated
2013-12-17 15:35:14

[ Watch the Video: Yellowstone Volcano Bigger Than Estimated ] Lee Rannals for redOrbit.com - Your Universe Online A supervolcano located in Yellowstone National Park is much larger than previously thought, according to research presented at the American Geophysical Union last week. The new study finds the supervolcano is about 2.5 times bigger than earlier estimates, stretching for more than 55 miles. Researchers used a network of seismometers situated around the national park to...

US Supervolcanoes: Yellowstone-Check, Utah-Check, Wait... Utah?

[ Watch the Video: Add Another Supervolcano To North America's List ] Brett Smith for redOrbit.com - Your Universe Online 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 some 5,000 times larger than the Mount St. Helens eruption in 1980, according to a new report published in the journal Geosphere. “In southern Utah, deposits from this single eruption...

Scientists Look At Supervolcano Life Cycle In Whole New Way
2013-10-11 14:49:13

Lee Rannals for redOrbit.com - Your Universe Online Scientists say they've discovered a new way to look at the life cycle of a supervolcano at a Yellowstone hotspot. University of Oregon researchers said that crystals of zircon from the Snake River Plain helped to solidify evidence of "recycled" super-volcanic magma chambers. This Yellowstone hotspot creates a conveyor belt style of volcanism because of the southwest migration of the North American plate at about 0.8 to 1.6 inches...

Supervolcanic Ash Can Transform Into Lava Miles Away From Eruption
2013-08-28 06:33:27

Lawrence LeBlond for redOrbit.com - Your Universe Online New research has taken a closer look at how ash produced from supervolcanoes can turn back into lava once it falls back to Earth. Supervolcanoes, such as the Yellowstone caldera, are capable of producing eruptions thousands of times stronger than normal volcanoes. Such a massive eruption can produce an ash cloud that is so hot it has the ability to re-form into lava once it hits the ground much farther away. This evidence was...

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. Abstracts for these and other Geosphere papers are available at...

Megavolcanoes Led To End-Triassic Extinction Allowing Dinosaurs To Evolve
2013-03-22 04:19:11

WATCH VIDEO: [Drilling Into The Jurassic In New Jersey] Lawrence LeBlond for redOrbit.com - Your Universe Online 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. Now, scientists have found evidence of another planetary cataclysm that occurred some 135 million years before the Cretaceous-Paleogene Extinction (CPE) event. An examination of evidence across three continents...

Studies Suggest Volcanic Eruptions Can Be Predicted
2012-02-03 06:01:44

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. In one study, published Thursday in the journal Nature, scientists investigate "caldera-forming volcanic eruptions," or eruptions that discharge such massive amount of magma that it can create a large depression in the...

Conductivity image hints volcano plume is bigger than thought University of Utah geophysicists made the first large-scale picture of the electrical conductivity of the gigantic underground plume of hot and partly molten rock that feeds the Yellowstone supervolcano. The image suggests the plume is even bigger than it appears in earlier images made with earthquake waves. "It's like comparing ultrasound and MRI in the human body; they are different imaging technologies," says geophysics...

Lake Toba
2014-04-08 13:26:50

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...
