Major deep carbon sink linked to microbes found near volcano chains

Up to about 19 percent more carbon dioxide than previously believed is removed naturally and stored underground between coastal trenches and inland chains of...

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...

New research supports volcanic origin of Kiruna-type iron ores

The origin of giant apatite-iron oxide ores of the so-called 'Kiruna-type' has been the topic of a long standing debate that has lasted for...

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...

Scientists argue for more comprehensive studies of Cascade volcanoes

The string of volcanoes in the Cascades Arc, ranging from California's Mt. Lassen in the south to Washington's Mt. Baker in the north, have...

Volcano cliffs can affect monitoring data

New research led by the University of East Anglia (UEA) reveals that sharp variations of the surface of volcanoes can affect data collected by...

Volcanic ash particles under the microscope

Volcanic ash is hazardous to many aspects of our lives. When airborne, it can damage aircraft: its particles abrade aeroplane surfaces and can even...

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?...
