Island arcs study reveals ancient connections between ocean chemistry and volcanic rocks

Bringing a novel approach to a classic problem, researchers have revealed how changes in ocean chemistry over the past 2 billion years have left...

Easter Island’s volcanic history suggests Earth’s mantle behaves quite differently than previously assumed

Geography textbooks describe the Earth's mantle beneath its plates as a well-mixed viscous rock that moves along with those plates like a conveyor belt....

Scientists uncover details of a catastrophic volcanic eruption and flood over 1,000 years ago

In the year 946 CE, the Changbaishan-Tianchi volcano, on the border between China and North Korea, erupted ferociously. The eruption released dozens of cubic...

Tongan volcanic eruption triggered by explosion equivalent to ‘five underground nuclear bombs,’ new research reveals

The Hunga Tonga underwater volcano was one of the largest volcanic eruptions in history, and now, two years later, new research from The Australian National University...

Geoscientists detect rapid uplift at unique volcano in Tanzania

When a volcano is about to erupt, the surrounding land puffs up like a squeezed balloon. The technical term is "transient deformation," and Virginia...

Tiny glass beads suggest the moon had active volcanoes when dinosaurs roamed Earth

Volcanoes were still erupting on the moon when dinosaurs roamed Earth, new research suggests. The evidence: three tiny glass beads plucked from the surface of the moon and brought...

New parameter enhances insights into the evolution of mantle’s redox states

The oxygen fugacity (fO2) of the mantle controls the speciation and mobility of volatiles within it, influencing the composition of volatiles released during mantle-derived...

Volcanic eruptions that warmed the planet millions of years ago shed light on how plants evolve, regulate climate

Scientists often seek answers to humanity's most pressing challenges in nature. When it comes to global warming, geological history offers a unique, long-term perspective. Earth's geological...

Recent volcanic ‘fires’ in Iceland began with vast magma pooling just beneath the surface, scientists report

Scientists from UC San Diego's Scripps Institution of Oceanography have detected geochemical signatures of magma pooling and melting beneath the subsurface during the "Fagradalsfjall...

New study disputes Hunga Tonga volcano’s role in 2023–24 global warm-up

New research from a collaborative team featuring Texas A&M University atmospheric scientist Dr. Andrew Dessler is exploring the climate impact of the 2022 Hunga...

Pompeii skeleton discovery shows another natural disaster may have made Vesuvius eruption even more deadly

Almost 2,000 years ago, Pliny the Younger wrote letters describing the shaking ground as Vesuvius erupted. Now, a collaborative study led by researchers from...

A ‘trilobite Pompeii’: Perfectly preserved fossils of ancient sea critters found buried in volcanic ash

If you've ever visited the fossil gallery of a natural history museum—or its gift shop, for that matter—you've probably seen the armored body remains...
