Volcanologist jams to the beat of the Earth’s drummer

“We’re Barely Listening to the U.S.’s Most Dangerous Volcanoes,” read the headline on a recent story in the New York Times, pointing to the...

Magma crystallization makes volcanoes more explosive

A new paper from scientists at The University of Manchester has discovered why some volcanic eruptions are more explosive than others. Basaltic eruptions are the...

Ice core source discovery adds to study of volcanic activity, climate...

A new discovery by University of Maine researchers that challenges the established volcanic source of particles found in an ice core from the South...

A new study determines the influence of the topography over ...

The emplacement of small-volume (<0,1km3) pyroclastic flows is strongly controlled by topography, according to a new study made by researchers of the Institute of...

Early warning signals heralded fatal collapse of Krakatau volcano

On 22 December 2018, a flank of the Anak Krakatau volcano plunged into the Sunda strait between the Indonesian islands of Sumatra and Java,...

Kimberlites: The only volcanic deposits that we know are from the...

Our planet formed around 4.54 billion years ago but few hints of this ancient world remain—just a small outcrop of rocks in northwestern Canada...

Ancient volcanoes reveal Earth’s recycled crust

Ancient volcanoes dating back billions of years could provide new insights into how the Earth's surface is recycled, according to scientists at the University...

Crack in Pacific seafloor caused volcanic chain to go dormant

From his geology lab at the University of Houston, Jonny Wu has discovered that a chain of volcanoes stretching between Northeast Asia and Russia...

Kīlauea lava fuels phytoplankton bloom off Hawai’i Island

When Kīlauea Volcano erupted in 2018, it injected millions of cubic feet of molten lava into the nutrient-poor waters off the Big Island of...

The ‘universal break-up criterion’ of hot, flowing lava?

Thomas Jones' "universal break-up criterion" won't help with meltdowns of the heart, but it will help volcanologists study changing lava conditions in common volcanic...

Detecting hydrothermal vents in volcanic lakes

Geothermal manifestations at Earth's surface can be mapped and characterized by a variety of well-established exploration methods. However, mapping hydrothermal vents in aquatic environments...

Jurassic world of volcanoes found in central Australia

An international team of subsurface explorers from the University of Adelaide in Australia and the University of Aberdeen in Scotland have uncovered a previously...

Ancient drop of water rewrites Earth’s history

The remains of a microscopic drop of ancient seawater has assisted in rewriting the history of Earth's evolution when it was used to re-establish...

Synchronization of ice cores using volcanic ash layers

Thin, brownish layers of a thickness of about a millimeter or two are sometimes observed in the whitish/transparent ice cores. These brown layers consist...

Scientists uncover deep-rooted plumbing system beneath ocean volcanoes

Cardiff University scientists have revealed the true extent of the internal 'plumbing system' that drives volcanic activity around the world. An examination of pockets of...

How to recognise where a volcano will erupt

On television, the eruption of volcano shoots magma right out of the top. However, it is not so uncommon that magma erupts from the...

Careful analysis of volcano’s plumbing system may give tips on pending...

A volcano will not send out an official invitation when it's ready to erupt, but a team of researchers suggest that scientists who listen...

‘Crystal clocks’ used to time magma storage before volcanic eruptions

The molten rock that feeds volcanoes can be stored in the Earth's crust for as long as a thousand years, a result which may...

Volcano eruption at different latitudes: A switch of hemispheric monsoon rainfall...

Volcanic eruptions eject sulfur dioxide gas high into the atmosphere, forming sulfate aerosol chemically, and block the incoming sunlight like an umbrella. This causes...
