More than 70 passive sensors on Mount Etna have captured the first radon measurements in volcanic plumes and show that radon could affect people around volcanoes.
Humanity’s carbon emissions are, by far, the largest disturbance to Earth’s steady state carbon cycle.
Hydrous silica-rich magmas can degas through connected bubble pathways when as little as 20% crystals are present, influencing transitions from explosive, Vulcanian-style eruptions to lava effusion.
High-precision airborne measurements, in combination with atmospheric modeling, suggest that the Katla subglacial caldera may be one of the planet’s biggest sources of volcanic carbon dioxide.
Scientists use 3-D imaging to reveal Solfatara crater’s inner plumbing.
A widely used technique to monitor sulfur dioxide was tweaked to focus on water vapor at Peru’s Sabancaya Volcano. Results show that the volcano steamed up prior to its 2016 eruption.
Researchers looking at geyser discharge water in Yellowstone National Park found that dissolved carbon dioxide could be involved in a geyser's eruption.
