What does the future of Kilauea hold?

Ever since Hawaii's Kilauea stopped erupting in August 2018, ceasing activity for the first time in 35 years, scientists have been wondering about the...

Mysterious Large-Magnitude Eruption that Covered the Mediterranean

The caldera-forming eruption of Campi Flegrei (Italy) 40,000 years ago is the largest known eruption in Europe during the last 200,000 years, but little...

New evidence suggests volcanoes caused biggest mass extinction ever

Biggest Mass Extinction Researchers say mercury buried in ancient rock provides the strongest evidence yet that volcanoes caused the biggest mass extinction in the history...

Driving force of volcanic super-hazards uncovered

Massey volcanologists have discovered the driving force behind superheated gas-and-ash clouds from volcanic eruptions, which may help save lives and infrastructure around the globe. Endangering...

Large volcanic eruptions can alter hurricane strength and frequency

A new study led by Lamont-Doherty Earth Observatory researcher Suzana Camargo and Université du Québec à Montréal's Francesco Pausata provides deeper insight into how...

Large volcanic eruption in Scotland may have contributed to prehistoric global...

Around 56 million years ago, global temperatures spiked. Researchers at Uppsala University and in the UK now show that a major explosive eruption from...

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...
