On the front lines in Kilauea

In the early spring, volcanologists monitoring the ground around Kilauea, the most active volcano on the island of Hawai'i, noticed a significant increase in...

‘Amazing snapshots’ plumb volcanic depths

Research shedding light on the internal "plumbing" of volcanoes may help scientists better understand volcanic eruptions and unrest. The University of Queensland-led study analysed crystals...

A volcanic binge and its frosty hangover

A major volcanic event could have triggered one of the largest glaciations in Earth's history -- the Gaskiers glaciation, which turned the Earth into...

Satellite images reveal interconnected plumbing system that caused Bali volcano to...

A team of scientists, led by the University of Bristol, has used satellite technology provided by the European Space Agency (ESA) to uncover why...

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...

Geological fingerprinting of volcanic ash

Volcanic ash consists of tiny particles containing minerals and glass. LMU researchers have now used a new analytical technique based on quantitative chemical analysis...

How to predict when a volcano will erupt

The eruption of a volcano can have devastating consequences – killing people and destroying livelihoods, as well as releasing vast amounts of ash into...

Scientists brew lava and blow it up to better understand volcanoes

What happens when lava and water meet? Explosive experiments with humanmade lava are helping to answer this important question. By cooking up 10-gallon batches of...

Scientists discover possible mantle mineral

Scientists long believed that Earth's lower mantle was composed of Bridgmanite (Mg,Fe)SiO3 and magnesiowüstite (Mg,Fe)O, in which Fe2+ dwells. This view changed when experiments...

Volcanoes fed by ‘mush’ reservoirs rather than molten magma chambers

Volcanoes are not fed by molten magma formed in large chambers finds a new study, overturning classic ideas about volcanic eruptions. Instead, the study suggests...

A microbe’s membrane helps it survive extreme environments

Within harsh environments like hot springs, volcanic craters and deep-sea hydrothermal vents -- uninhabitable by most life forms -- microscopic organisms are thriving. How?...

New automated volcano warning system forecasts imminent eruptions

Scientists have developed an automated early warning system for volcanic eruptions, according to a new study. The new system helped government officials warn the...

A large volcanic eruption shook Deception Island 3,980 years ago

A large volcanic eruption shook Deception Island, in Antarctica, 3,980 years ago, and not 8,300, as it was previously thought, according to an international...

Volcanoes and glaciers combine as powerful methane producers

Large amounts of the potent greenhouse gas methane are being released from an Icelandic glacier, scientists have discovered. A study of Sólheimajökull glacier, which flows...

What is a Plutonic Igneous Rock?

In geology, a pluton is a body of intrusive igneous rock (called a plutonic rock) that is crystallized from magma slowly cooling below the...

Life cycle of sulphur predicts location of valuable minerals

A team of researchers from The University of Western Australia and two Canadian universities has applied a first-of-its-kind technique that measures the long-term life...

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 Pompeii evidence rewrites Vesuvius eruption history

A newly-discovered inscription at Pompeii proves the city was destroyed by Mount Vesuvius after October 17, 79 AD and not on August 24 as...

GeoSEA array records sliding of Mount Etna’s southeastern flank

As Europe's most active volcano, Mount Etna is intensively monitored by scientists and Italian authorities. Satellite-based measurements have shown that the southeastern flank of...

Volcano researcher learns how Earth builds supereruption-feeding magma systems

To figure out where magma gathers in the earth's crust and for how long, Vanderbilt University volcanologist Guilherme Gualda and his students traveled to...
