How Magma Climbs the Crustal Ladder Between Eruptions

The road cut seems rather dull and gray at first, but the tuff and pumice rocks hold the secrets of a volcano. Covered in...

New insight into how magma feeds volcanic eruptions

A novel research study by scientists at the University of Liverpool has provided new insights into how molten rock (magma) moves through the Earth's...

Scientists eavesdrop on volcanic rumblings to forecast eruptions

A new study has shown that monitoring inaudible low frequencies called infrasound produced by a type of active volcano could improve the forecasting of...

Tidal cycles could help predict volcanic eruptions

Just before a surprise eruption of New Zealand's Ruapehu volcano in 2007, seismic tremor near its crater became tightly correlated with twice-monthly changes in...

Tiny crystals could help predict volcanic eruptions

They can be as small as a grain of salt, but tiny crystals that form deep in volcanoes may be the key for advance...

The seemingly unremarkable crystals that could help predict volcanic eruptions

They may look inconspicuous and unremarkable, and most people wouldn't notice them, but small crystals in volcanic rocks, such as lava, may hold the...

A close-up look at an uncommon underwater eruption

On July 18, 2012, passengers on an airline flight over the Southwest Pacific Ocean glimpsed something unusual -- a raft of floating rock known...

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....

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...

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...

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...

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...

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...

New study analyzes volcanic fatalities in more detail than ever before

It is hoped the findings, published recently in the Journal of Applied Volcanology, will help increase our understanding of volcanic hazards and the subsequent...

Large volcanic eruptions in Tropics can trigger El Niño events

Explosive volcanic eruptions in the tropics can lead to El Niño events, those notorious warming periods in the Pacific Ocean with dramatic global impacts...
