Tonga Eruption May Temporarily Push Earth Closer to 1.5°C of Warming
The underwater eruption of Hunga Tonga–Hunga Ha‘apai sent megatons of water vapor into the stratosphere, contributing to an increase in global warming over the next 5 years.
Martian Lava, Up Close and Personal
The Mars 2020 Perseverance Rover conducted the first investigation of volcanic rocks where they stand in their original configuration on the surface of Mars.
Mapping the Fizzy Brines and Fluid-Filled Fractures Below a Volcano
Seismic tools reveal where hydrothermal fluids lie beneath the Uturuncu volcano in Bolivia and hint at their composition.
Quantification of Subaerial Volcanism and its Products
Researchers estimate the mass of volcanic products that erupted above sea level from 1980 to 2019 by volcanoes worldwide and the average eruptive rates of each magmatic province.
Rapid Evolution of Volcanic Systems Reflected in Magnetics
Spatiotemporal magnetic monitoring along with InSAR models is a powerful tool to image magmatic, hydrothermal, and mechanical changes within the volcanic edifice of the Piton de la Fournaise.
Crystals Track Magma Movement Beneath Iceland
Crystals from Fagradalsfjall’s eruption mark how mantle magma might have been moving years before geophysical indicators alerted scientists to unrest.
UV Radiation Contributed to Earth’s Biggest Mass Extinction
To find the first direct evidence of heightened UV radiation during the end-Permian mass extinction, researchers turned to chemical evidence preserved in pollen grains.
Centuries-Old Archive Reveals Far-Flung Impacts of Major Eruptions
Weather records preserved by staff and students at Williams College reveal cool spells in New England after volcanic blasts in Indonesia and South Asia.
Baked Contacts Focus a Lens on Ancient Lava Flows
Two studies, conducted 40 years apart, show how combining field observations and thermal modeling can reconstruct the history of massive lava flows and how they altered the surrounding landscape.
