Satellite Observations Could Help Forecast an Eruption’s End
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.
Caught on Camera: Volcanic Bombs in Flight
A recent paper in Reviews of Geophysics revealed new insights into the flight patterns of solid and molten debris flung out of volcanos during explosive eruptions.
A Promising New Tool for Forecasting Volcanic Hazards
A new model that simulates the behavior of surging ash clouds may help scientists to better predict the hazards associated with the deadliest type of volcanic flows.
Volcano’s Toxic Plume Returns as Stealth Hazard
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.
Can Water Vapor Help Forecast When a Volcano Will Blow?
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.
Homemade Lava Flows Fuse Science with Art on Video
An artist’s impulse to recreate natural landscapes leads to fiery scientific explorations that elucidate the behavior of erupting lava and the solid shapes it becomes.
New Volcanic Island Unveils Explosive Past
A recent volcanic eruption near Tonga in the southwest Pacific created a new island, giving scientists a rare opportunity to explore the volcanic record of this remote region.
Can Volcanic Gas Levels Predict an Eruption?
Researchers test whether the changing composition of volcanic gas can signal a coming eruption in Chile’s Villarrica volcano.
An Autonomous Boat to Investigate Acidic Crater Lakes
A novel aquatic drone ventured into highly acidic waters to test the feasibility of remotely exploring and surveying hazardous volcanic lakes.
