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...

Yellowstone super-volcano has a different history than previously thought

The long-dormant Yellowstone super-volcano in the American West has a different history than previously thought, according to a new study by a Virginia Tech...

Study finds deep subterranean connection between two Japan volcanoes

Scientists have confirmed for the first time that radical changes of one volcano in southern Japan was the direct result of an erupting volcano...

‘Ring around bathtub’ at giant volcano field shows movement of subterranean...

The Laguna del Maule volcanic complex in Chile is a large, complicated and explosive landscape that, oddly, lacks the classic cone seen on many...

Masses of methane from mud volcanoes

In the seabed, there are numerous microorganisms that play an important role in the global carbon cycle. Up to now, however, it has not...

Volcanic activity, declining ocean oxygen triggered mass extinction of ancient organisms

Global climate change, fueled by skyrocketing levels of atmospheric carbon dioxide, is siphoning oxygen from today's oceans at an alarming pace -- so fast...

Scientists use 4D scanning to predict behavior of volcanoes

Scientists are using the latest in 4D technology to predict the behaviour of lava flows and its implications for volcanic eruptions. The results explain why...

New way to estimate magma beneath Yellowstone supervolcano

Researchers at Washington State University and the University of Idaho have found a new way to estimate how fast magma is recharging beneath the...

Japanese student discovers new crustacean species in deep sea hydrothermal vent

A new species of microcrustacean (Stygiopontius ) was collected from a submarine hot spring (hydrothermal vent) of a volcanic seamount (Myojin-sho caldera) in the...

Volcanic hazard scenarios: Mount Taranaki, New Zealand

Over the last 5000 years, Mount Taranaki volcano, located in the westernmost part of New Zealand's North Island, produced at least 16 Plinian-scale explosive...
