An international team of geoscientists led by a volcanologist at Rutgers University-New Brunswick has discovered that, contrary to present scientific understanding, ancient volcanoes continued to spew carbon dioxide into the atmosphere from deep within the Earth long past their period of eruptions.

Research reveals sources of CO2 from Aleutian-Alaska Arc volcanoes
Scientists have wondered what happens to the organic and inorganic carbon that Earth’s Pacific Plate carries with it as it slides into the planet’s interior along the volcano-studded Ring of Fire.
Updating our understanding of Earth’s architecture
New models that show how the continents were assembled are providing fresh insights into the history of the Earth and will help provide a better understanding of natural hazards like earthquakes and volcanoes.
As Big As It Gets, Hunga Volcano Comparable To Krakatoa
New research by an international team from 17 countries including Lawrence Livermore National Laboratory (LLNL) scientist Keehoon Kim demonstrates that based on atmospheric pressure waves recorded by global barometers, the Hunga explosion was comparable in size to that of the 1883 Krakatoa eruption.
Let’s talk about the 1,800-plus ‘young’ volcanoes in the U.S. Southwest
The landscape of the southwestern U.S. is heavily scarred by past eruptions of monogenetic volcanoes, and a new study marks a step toward understanding future risks for the region.
What lies beneath: Volcanic secrets revealed
Lava samples have revealed a new truth about the geological make-up of the Earth’s crust and could have implications for volcanic eruption early warning systems, a University of Queensland-led study has found.
Study reveals threat of catastrophic supervolcano eruptions ever-present
Curtin scientists are part of an international research team that studied an ancient supervolcano in Indonesia and found such volcanoes remain active and hazardous for thousands of years after a super-eruption, prompting the need for a rethink of how these potentially catastrophic events are predicted.
Volcanoes acted as a safety valve for Earth’s long-term climate
Scientists at the University of Southampton have discovered that extensive chains of volcanoes have been responsible for both emitting and then removing atmospheric carbon dioxide (CO2) over geological time.
Minor Volcanic Eruptions Could ‘Cascade’ Into Global Catastrophe, Experts Argue
Currently, much of the thinking around risks posed by volcanoes follows a simple equation: the bigger the likely eruption, the worse it will be for society and human welfare.
In lonely desert landscapes, hunting for clues about pyroclastic surges
The history of pyroclastic surges is written in the landscapes they ravage. Volcanic dunes and other deposits hold debris from ancient eruptions, as do craters marking sites of ancient blasts. This study focuses on Ubehebe and El Elegante.
Iceland’s Fagradalsfjall is erupting. This UB expert helps predict where lava may go
Mattia de’ Michieli Vitturi, a geology faculty member and a mathematician, uses computational modeling to help officials in Iceland understand where lava may flow BUFFALO, N.Y. — The eruption of Fagradalsfjall on Iceland’s Reykjanes Peninsula, with lava emerging from multiple…
When Volcanoes Go Metal
What would a volcano – and its lava flows – look like on a planetary body made primarily of metal? A pilot study offers insights into ferrovolcanism that could help scientists interpret landscape features on other worlds.
Volcanic activity and changes in Earth’s mantle were key to rise of atmospheric oxygen
Evidence from rocks billions of years old suggest that volcanoes played a key role in the rise of oxygen in the atmosphere of the early Earth.
New geochemical tool reveals origin of Earth’s nitrogen
Researchers at Woods Hole Oceanographic Institution (WHOI), the University of California Los Angeles (UCLA) and their colleagues used a new geochemical tool to shed light on the origin of nitrogen and other volatile elements on Earth, which may also prove useful as a way to monitor the activity of volcanoes. Their findings were published April 16, 2020, in the journal Nature.
Supercomputer Models Accurately Simulate Tsunamis from Volcanic Events
Researchers at the University of Rhode Island (URI) used San Diego Supercomputer Center’s (SDSC) Comet supercomputer to show that high-performance computer modeling can accurately simulate tsunamis from volcanic events. Such models could lead to early-warning systems that could save lives and help minimize catastrophic property damage.
Taal volcano threatens life, climate, agriculture
CORNELL UNIVERSITY MEDIA RELATIONS OFFICEJan. 22, 2020 Taal volcano threatens life, climate, agriculture The Taal volcano in the Philippines has eased its dramatic spewing of ash, but researchers monitoring the volcano say the possibility of a major eruption remains. Esteban…
Rutgers Geology Museum Hosts Open House
Presentations on natural disasters such as earthquakes, volcanoes and their impacts will be held in Scott Hall and are open to the public at the Rutgers Geology Museum’s 52nd Annual Open House. There will also be hands-on activity sessions for kids, a mineral sale and rock and mineral identification in Scott Hall, and make-and-take stations in the Rutgers Geology Museum. Field Station Dinosaurs will bring its baby Hadrosaurus puppet and will also offer hands-on activities for visitors. All events are free and no preregistration is required.
