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.
Offshore observations by cabled ocean-bottom pressure recorders have revealed details of the 2015 eruption of Axial Seamount submarine volcano in the Pacific Ocean.
It took more than a decade, but a bill that funds U.S. volcano monitoring efforts and establishes a single system became law on 12 March.
Optimizing the Use of Volcano Monitoring Database to Anticipate Unrest; Yogyakarta, Indonesia, 26–29 November 2018
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 network of buoys provides a first glimpse of the seafloor beneath a volatile Italian caldera.
Yellowstone Lake, far from any ocean, hosts underwater hot springs similar to those on mid-ocean ridges. A research team is investigating the processes that drive the lake’s hydrothermal systems.
Researchers studying past volcanic activity found they could retrospectively predict when outflows of molten rock would cease for about 40% of effusive eruptions, the kind that produces flowing lava.
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 have developed a new numerical model that can, for the first time, solve for both the speed and the path of a propagating dike.
