New clues to the origin of massive underwater volcano, Tamu Massif

The discovery of Tamu Massif, a gigantic volcano located about 1,000 miles east of Japan, made big news in 2013 when researchers reported it...

Water drives explosive eruptions: Magma is wetter than we thought

Volatile elements in magma, primarily water, drive explosive volcanic eruptions. The tricky part is determining just how much volatile content was present before the...

Discovery of rare lava lake on remote sub-Antarctic island

A team of scientists has discovered a rare lava lake on a remote and inaccessible sub-Antarctic island. There are around 1500 land-based volcanoes on...

Earthquake swarms reveal missing piece of tectonic plate-volcano puzzle

Deep under the ocean bed, a sinking tectonic plate causes a "swarm" of earthquakes, feeding molten rock into newly forming volcanoes, new research has...

A 49 kilometers high volcanic ash column rose up over the...

The Ilopango’s volcano eruption (also known as Tierra Blanca Joven or TBJ) occurred approximately 1,500 years ago. Pyroclastics currents were dispersed over much of...

Rare volcanic rocks lift lid on dangers of little-studied eruptions

Unusual rocks discovered on a remote mountainside have alerted scientists to the dangers posed by a little-studied type of volcano. Researchers say that the rocks,...

How Earth’s mantle is like a Jackson Pollock painting

In countless grade-school science textbooks, the Earth's mantle is a yellow-to-orange gradient, a nebulously defined layer between the crust and the core. To geologists, the...

From Earth’s deep mantle, scientists find a new way volcanoes form

Far below Bermuda's pink sand beaches and turquoise tides, geoscientists have discovered the first direct evidence that material from deep within Earth's mantle transition...

The Central Andes had the largest volcanic eruption of the last...

Cerro Blanco Volcanic Complex, located in the south of the Altiplano-Puna plateau, erupted around 4,200 years ago. But it was not an ordinary event....

Iceland volcano eruption in 1783-84 did not spawn extreme heat wave

An enormous volcanic eruption on Iceland in 1783-84 did not cause an extreme summer heat wave in Europe. But, as Benjamin Franklin speculated, the...

Study on explosive volcanism during ice age provides lessons for today’s...

A University of Oklahoma-led study recently found that explosive volcanic eruptions were at least 3-8 times more frequent during the peak of the Late...

What does the future of Kilauea hold?

Ever since Hawaii's Kilauea stopped erupting in August 2018, ceasing activity for the first time in 35 years, scientists have been wondering about the...

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...
