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...

Volcano under ice sheet suggests thickening of West Antarctic ice is...

A region of West Antarctica is behaving differently from most of the continent's ice: A large patch of ice there is thickening, unlike other...

New Antarctic rift data has implications for volcanic evolution

New data revealing two tectonic plates fused to form a single Antarctic Plate 15 million years later than originally predicted and this extra motion...

Mantle xenon has a story to tell

The Earth has been through a lot of changes in its 4.5 billion year history, including a shift to start incorporating and retaining volatile...

Size matters: If you are a bubble of volcanic gas

The chemical composition of gases emitted from volcanoes -- which are used to monitor changes in volcanic activity -- can change depending on the...

Platinum is key in ancient volcanic related climate change

Supervolcanoes are one of Mother Nature's deadliest phenomena, and when they erupt, they can change the climate of the entire planet. To get a glimpse...
