Magma-limestone interaction can trigger explosive volcanic eruptions -- and affect the global carbon cycle
In a new study researchers from Sweden and Italy show what happens when magma meets limestone on its way up to the surface. Magma-limestone interaction might help explain why volcanoes like Vesuvius in Italy and Merapi in Indonesia are particularly explosive and, moreover, it helps us to understand another source of natural carbon released to the atmosphere by volcanoes.

Geophysicists challenge traditional theory underlying the origin of mid-plate volcanoes
Geophysicists from Virginia Tech and Caltech point to a super-hot layer beneath the tectonic plates as the place of origin for volcanoes, as opposed to deep within the Earth's core. (2014-12-04)

Scientists reveal an explosive secret hidden beneath seemingly trustworthy volcanoes
An international team of volcanologists working on remote islands in the Galápagos Archipelago has found that volcanoes which reliably produce small basaltic lava eruptions hide chemically diverse magmas in their underground plumbing systems - including some with the potential to generate explosive activity. These volcanoes might undergo unexpected changes to sudden such activity in the future. (2020-07-28)

One vent just isn't enough for some volcanoes
One vent just isn't enough for some volcanoes: the curious case of Mount Etna's wandering craters. (2016-09-02)

Deep-sea volcanoes don't just produce lava flows, they also explode!
Most deep-sea volcanoes produce effusive lava flows rather than explosive eruptions, both because the levels of magmatic gas tend to be low, and because the volcanoes are under a lot of pressure from the surrounding water. But by using an ion microprobe, Christoph Helo, a PhD student in McGill's Department of Earth and Planetary Sciences, has now proved that explosive eruptions can also occur. (2011-03-28)

Volcanic activity on Mars could offer clues to planet's history
The study of three of the oldest and most explosive volcanoes on Mars could provide insights into the planet's history, especially implications for water sources. (2009-07-12)

First-ever 3-D image created of the structure beneath Sierra Negra volcano
The Galapagos Islands are home to some of the most active volcanoes in the world, with more than 50 eruptions in the last 200 years. Yet until recently, scientists knew far more about the history of finches, tortoises, and iguanas than of the volcanoes on which these unusual fauna had evolved. Now research out of the University of Rochester is providing a better picture of the subterranean plumbing system that feeds the Galapagos volcanoes. (2014-03-05)

Scientists have exploited crystals from lavas to unravel the records of volcanic eruptions. (2008-08-28)

Evidence from Hawaiian volcanoes shows that Earth recycles its crust
Rutgers University geological sciences professor Claude Herzberg offers new evidence that parts of the Earth's crust that long ago dove hundreds or thousands of kilometers into the Earth's interior have resurfaced in the hot lava flow of Hawaiian volcanoes. Writing in Nature, Herzberg claims to have found telltale chemical evidence at Mauna Kea that pieces of this submerged crust have been forced up through plumes and now make up most of this volcano's lava flow. (2006-11-29)

Crystals reveal the danger of sleeping volcanoes
Most active volcanoes on Earth are dormant and are normally not considered hazardous. A team of volcanologists from the University of Geneva has devised a technique that can predict their devastating potential. The scientists used zircon, a tiny crystal contained in volcanic rocks, to estimate the volume of magma that could be erupted once Nevado de Toluca volcano (Mexico) will wake up from its dormancy. Up to 350 km3 of magma are currently lying below. (2020-11-05)

Los Alamos volconologist highlights education collaboration
A collaboration between the U.S. Department of Energy's Los Alamos National Laboratory and the University of New Mexico has resulted in a successful, one-of-a-kind educational program where students can get a first-hand glimpse into the esoteric world of volcanology. (2002-05-31)

How do you forecast eruptions at volcanoes that sit 'on the cusp' for decades?
Some volcanoes take their time--experiencing protracted, years-long periods of unrest before eventually erupting. This makes it difficult to forecast when they pose a danger to their surrounding areas, but Carnegie's Diana Roman and Penn State's Peter LaFemina are trying to change that. (2019-08-06)

Another clue for fast motion of the Hawaiian hotspot
Recent studies have suggested that the Hawaiian hotspot moved relatively quickly southward in the period from 60 to about 50 million years ago. This hypothesis is supported by a new study of Kevin Konrad and colleagues. They have evaluated new rock dating of the Rurutu volcanic chain and added data from the Hawaiian-Emperor chain and the Louisville chain. It shows that the Hawaiian-Emperor hotspot displays strong motion between 60 and 48 million years ago. (2018-02-27)
