Yellowstone’s history of hydrothermal explosions over the past 14,000 years

While much of public attention on Yellowstone focuses on its potential to produce large supereruptions, the hazards that are much more likely to occur...

Arc volcanoes are wetter than previously thought, with scientific and economic...

The percentage of water in arc volcanoes, which form above subduction zones, may be far more than many previous studies have calculated. This increased amount...

Volcanoes at fault if the Earth slips

The 2016 Kumamoto earthquakes shocked inhabitants of the western island of Kyushu, causing hundreds of casualties and serious damage to vital infrastructure. The epicenter...

A swarm of 85,000 earthquakes at the Antarctic Orca submarine volcano

Volcanoes can be found even off the coast of Antarctica. At the deep-sea volcano Orca, which has been inactive for a long time, a...

The oxidation of volcanoes—a magma opus

A new, Yale-led study unlocks the science behind a key ingredient—namely oxygen—in some of the world's most violent volcanoes. The research offers a new model...

Hidden weaknesses within volcanoes may cause volcano collapse

Lava domes form at the top of many volcanoes when viscous lava erupts. When they become unstable, they can collapse and cause a hazard....

Hidden weaknesses within volcanoes may cause their collapse

Lava domes form at the top of many volcanoes when viscous lava erupts. When they become unstable, they can collapse and cause a hazard....

Deep down temperature shifts give rise to eruptions

The astonishing force of the Tonga volcanic eruption shocked the world, but the fact that this underwater volcano actually erupted came as less of...

Pink pumice key to revealing explosive power of underwater volcanic eruptions

In research published in the Nature portfolio journal Communications Earth and Environment, the researchers including Professor Scott Bryan, Dr Michael Jones and PhD candidate...

Tonga eruption is one for the record books

The recent violent volcanic eruption on the Pacific island nation of Tonga is believed to be one of the strongest ever recorded, and future...

Sierra Nevada range should celebrate two birthdays

When geologist Elizabeth Miller started mapping a fault system in Death Valley, she questioned the origin of some sedimentary rocks previously assumed to be...

‘Volcanic winter’ likely contributed to ecological catastrophe 250 million years ago

A team of scientists has identified an additional force that likely contributed to a mass extinction event 250 million years ago. Its analysis of...

Let’s talk about the 1,800-plus ‘young’ volcanoes in the US Southwest

They're born. They live once, erupting for a period that might last for days, years or decades. Then, they go dark and die. This narrative...

How to better identify dangerous volcanoes

Volcanologists have long been troubled by two questions: When exactly will a volcano erupt next? And how will that eruption unfold? Will the lava...

What lies beneath: Volcanic secrets revealed

Lava samples have revealed a new truth about the geological make-up of the Earth's crust and could have implications for volcanic eruption early warning...

A journey into an Alaskan volcano

I'm writing this note from the Steadfast; an old 108 ft long crabber boat equipped with a helipad, crane, five state rooms, kitchen, living...

Volcanic eruptions may have spurred first ‘whiffs’ of oxygen in Earth’s...

A new analysis of 2.5-billion-year-old rocks from Australia finds that volcanic eruptions may have stimulated population surges of marine microorganisms, creating the first puffs...

Volcanism drove rapid ocean deoxygenation during the time of the dinosaurs

Ocean deoxygenation during the Mesozoic Era was much more rapid than previous thought, with CO2 induced environmental warming creating ocean 'dead zones' over timescales...

Volcanoes acted as a safety valve for Earth’s long-term climate

Scientists at the University of Southampton have discovered that extensive chains of volcanoes have been responsible for both emitting and then removing atmospheric carbon...

Giant friction experiment at Kilauea volcano

On April 30, 2018, on the eastern flank of Hawaii's Kīlauea volcano, lava suddenly drained from a crater that had been spewing lava for...
