The Cozier the Better for Bubbles Inside Powerful Volcanoes

Study suggests that powerful volcanic blasts occur due in part to how light vapor bubbles migrate and accumulate in some parts of shallow volcanic chambers. Researchers say these bubbles maneuver their way through crystal filled magma until they settle in these open-spaced reservoirs – areas without many crystals – and build up the necessary energy for an impending eruption.

Making Magma Helps Researchers Understand Volcanoes

The best way to figure out how something is made is to take it apart and put it back together again. That is what Jessica Larsen and her students do at the Geophysical Institute’s Petrology Lab in order to understand active volcanoes in Alaska.

How Rivers of Hot Ash and Gas Move When a Supervolcano Erupts

greg-valentine-slides.jpg

New research in Nature Communications sheds light on what happens when a supervolcano erupts. The study combines recent lab tests with vintage field data — some of it captured in colorful Kodachrome slides — to provide insight on how rivers of hot ash and gas travel huge distances in supereruptions.

Study Challenges Widely Accepted Theory of Yellowstone Formation

82870.jpg

Understanding the complex geological processes that form supervolcanoes could ultimately help geologists determine what triggers their eruptions. A new study using an advanced computer model casts doubt on previously held theories about the Yellowstone supervolcano’s origins, adding to the mystery of Yellowstone’s formation.

Explosive Underwater Volcanoes Were a Major Feature of ‘Snowball Earth’

16_05Snowball_Earth_white.jpg

Around 720-640 million years ago, much of the Earth’s surface was covered in ice during a glaciation that lasted millions of years. Explosive underwater volcanoes were a major feature of this ‘Snowball Earth’, according to new research led by the University of Southampton.

Evidence of Past Volcanic Activity in the Caribbean Sea

105927_web.jpg

Reconstructing the magnitude of past volcanic eruptions is important in informing predictions about future eruptions and hazards. This is difficult to accomplish from records on land -- old eruptions are often eroded away, buried beneath later eruptions, or obscured by vegetation and soil. Most volcanoes are close to the oceans, so much of the erupted material falls into seawater and accumulates on the seafloor.

New ‘Geospeedometer’ Confirms Super-Eruptions Have Short Fuses

A new "geospeedometer" that can measure the amount of time between the formation of an explosive magma melt and an eruption confirms that the process took less than 500 years in several ancient super-eruptions.
