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...

Siberian volcanic eruptions caused extinction 250 million years ago

A team of scientists has found new evidence that the Great Permian Extinction, which occurred approximately 250 million years ago, was caused by massive...

Scientists locate potential magma source in Italian supervolcano

Scientists have found the first direct evidence of a so-called 'hot zone' feeding a supervolcano in southern Italy that experts say is nearing eruption...

Massive Antarctic volcanic eruptions linked to abrupt Southern hemisphere climate changes

New findings published today in the Proceedings of the National Academy of Sciences of the United States of America (PNAS) by Desert Research Institute...

New research uses satellites to predict end of volcanic eruptions

Researchers from the University of Hawai'i at Mānoa (UHM) School of Ocean and Earth Science and Technology (SOEST) recently discovered that infrared satellite data...

Crystals help volcanoes cope with pressure

University of Alaska Fairbanks researchers have discovered that volcanoes have a unique way of dealing with pressure -- through crystals. According to a new study...

A fresh view on volcanic plumbing systems

Volcanic eruptions such as Mount St. Helens' in 1980 show the explosiveness of magma moving through Earth's crust. Now geologists are excited about what...

Tree rings pinpoint eruption of Icelandic volcano to half a century...

An international group of researchers has dated a large volcanic eruption in Iceland to within a few months. The eruption, which is the oldest...
