Satellite data have revealed that ground radiant temperatures around volcanoes rose in the years leading up to eruptions. The observation may help in forecasting future volcanic activity.
A theoretical model coupled to lab experiments on turbulent jets with reversing buoyancy sheds new light on the role of wind in controlling the dynamics of volcanic eruptive columns.
Impact and turbulence models for river tremor are adapted and combined into a model that predicts the amplitude and frequency content of volcanic eruption tremor.
Four decades of research into biophysical responses to the 1980 eruption of Mount St. Helens have vastly improved our understanding of how landscapes react to cataclysmic disturbances.
Researchers used a combination of ground and space-based measures to look for warning signs for the flank collapse at Anak Krakatau in 2018, which triggered a tsunami that killed hundreds.
Little seismic unrest preceded the 2014 eruption of a stratovolcano in Indonesia, which suggests that the eruption was kick-started internally by volatile-triggered overpressure.
A new biography details the life and legacy of the scientist who died on Mount St. Helens.
Roughly 1,500 years ago, the Tierra Blanca Joven eruption blanketed Central America in ash and likely displaced Maya settlements, new research shows.
A research team from Ecuador’s Geophysical Institute keeps a close eye on an unusually active and unstable volcano in the nation’s remote jungles.
Evidence from volcanic crystals sheds light on magma storage under Mount Agung and helps explain this giant volcano’s frequent eruptions.
