Geologists Make Their Own Lava to Prep for Explosive Experiments (Video Available)

University at Buffalo

The lava-making operation — one of the largest in the world — will provide a rare, close-up view of the interplay between molten rock and water, an interaction that can enhance the explosive potential of volcanoes.

Scientists Gain Supervolcano Insights From Wyoming Granite

University of Wyoming

Geophysical monitoring of the ground above active supervolcanoes shows that it rises and falls as magma moves beneath the surface of the Earth. Silica-rich magmas like those in the Yellowstone region and along the western margin of North and South America can erupt violently and explosively, throwing vast quantities of ash into the air, followed by slower flows of glassy, viscous magma.

The Cozier the Better for Bubbles Inside Powerful Volcanoes

Georgia Institute of Technology

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

University of Alaska Fairbanks

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

University at Buffalo

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

University of Illinois at Urbana-Champaign

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’

University of Southampton

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.

UO-Led Expedition Probes Undersea Magma System

University of Oregon

A team of University of Oregon scientists is home after a month-long cruise in the eastern Mediterranean, but this was no vacation. The focus was the plumbing system of magma underneath the island of Santorini, formed by the largest supervolcanic eruption in the past 10,000 years.
