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.
High levels of carbon dioxide and hydrogen sulfide emitted by volcanic outgassing caused a deadly accident near Rome, Italy, in 2011, geoscientists have shown.
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.
A team of volcanologists, chemists, physicists, and engineers from around the world test novel techniques at Central America’s two largest degassing volcanoes.
Readings from a sensor for the radioactive gas near summit craters of the Italian volcano reveal signatures of such processes as seismic rock fracturing and sloshing of groundwater and other fluids.
Scientists use 3-D imaging to reveal Solfatara crater’s inner plumbing.
During a closely watched eruption, plumes of harmful sulfur dioxide gas morphed into “plumerangs” of sulfuric-acid-rich aerosols that descended on populated parts of Iceland.
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.
