Chemical tipping point of magma determines explosive potential of volcanoes

Volcanic eruptions are the most spectacular expression of the processes acting in the interior of any active planet. Effusive eruptions consist of a gentle...

Unearthing the underground effects of earthquakes and volcanoes

Most of what we know about earthquakes and volcanoes is based on what we can observe at the Earth's surface. However, most of the...

Submarine volcanoes add to ocean soundscape

Most volcanoes erupt beneath the ocean, but scientists know little about them compared to what they know about volcanoes that eject their lava on...

Time between world-changing volcanic super-eruptions less than previously thought

After analysing a database of geological records dated within the last 100,000 years, a team of scientists from the University of Bristol has discovered...

Eruption clues: Researchers create snapshot of volcano plumbing

Much like a forensic team recreates a scene to determine how a crime was committed, researchers at the University of New Hampshire are using...

When magma prevents volcanic eruptions

A spectacular proof of our planet's activity, calderas are huge topographic depressions, similar to flat-bottomed craters, with a diameter of several tens of kilometres....

A Series of Fortunate Events: Antarctic Zircons Tell Story of Early...

Geoscientists from Michigan Technological University, University of Wisconsin Oshkosh and ETH Zurich have traced the age and chemical signatures stored in tiny zircon minerals...

Climate change could increase volcano eruptions

Shrinking glacier cover could lead to increased volcanic activity in Iceland, warn scientists. A new study, led by the University of Leeds, has found that...

High-latitude volcanic eruptions have global impact

Volcanic eruptions emit sulfate aerosols via volcanic plumes, which may stay in the stratosphere for months to years, reflecting sunlight back into space, cooling...

When water met iron deep inside the Earth, did it create...

Reservoirs of oxygen-rich iron between the Earth's core and mantle could have played a major role in Earth's history, including the breakup of supercontinents,...

Is Iceland’s tallest volcano awakening?

Two women and a boy took refuge on the roof … but it was carried away by the deluge of water, and as far...

How to turn a volcano into a power station

Ethiopia tends to conjure images of sprawling dusty deserts, bustling streets in Addis Ababa or the precipitous cliffs of the Simien Mountains – possibly...

Magma held in ‘cold storage’ before giant volcano eruption

Long Valley, California, has long defined the "super-eruption." About 765,000 years ago, a pool of molten rock exploded into the sky. Within one nightmarish...

Future volcanic eruptions could cause more climate disruption

Major volcanic eruptions in the future have the potential to affect global temperatures and precipitation more dramatically than in the past because of climate...

Yellowstone Spawned Twin Super-Eruptions that Altered Global Climate

A new geological record of the Yellowstone supervolcano's last catastrophic eruption is rewriting the story of what happened 630,000 years ago and how it...

Ice sheets may melt rapidly in response to distant volcanoes

Volcanic eruptions have been known to cool the global climate, but they can also exacerbate the melting of ice sheets, according to a paper...

New magma pathways after giant lateral volcano collapses

Giant lateral collapses are huge landslides occurring at the flanks of a volcano. Giant lateral collapses are rather common events during the evolution of...

Scientists determine source of world’s largest mud eruption

On May 29, 2006, mud started erupting from several sites on the Indonesian island of Java. Boiling mud, water, rocks and gas poured from...

Is it gonna blow? Measuring volcanic emissions from space

Late last month, a stratovolcano in Bali named Mount Agung began to smoke. Little earthquakes trembled beneath the mountain. Officials have since evacuated thousands...

Researchers document one of planet’s largest volcanic eruptions

Washington State University researchers have determined that the Pacific Northwest was home to one of the Earth's largest known volcanic eruptions, a millennia-long spewing...
