Icelandic Eruption Caused Record-Breaking Sulfur Dioxide Release
Satellite and ground-based data reveal sulfur dioxide flux, trace element release, and preeruption magma movement.
Fewer Tropical Cyclones Form After Volcanic Eruptions
Volcanic eruptions aren't all bad—in some cases, they can lower the frequency of tropical cyclones in the North Atlantic by emitting sulfate aerosols.
Can We Predict How Volcanic Ash Disperses After an Eruption?
Researchers investigate what factors influence how particles from a plume spread following a volcanic eruption.
Massive Carbon Dioxide Stores Beneath Mammoth Mountain
Gas in rocky pores beneath the surface of California's Mammoth Mountain could fuel dangerous carbon dioxide emissions for the next 28 to 1100 years.
Radar Technique Shows Magma Flow in 2014 Cape Verde Eruption
The European Space Agency's Sentinel-1 satellite captures volcanic surface changes that reveal the flow below.
Scientists Discover a New Source of Atmospheric Carbon Dioxide
In an African region where continental crust is pulling apart and fracturing—the East African Rift zone—the area's many faults are slowly releasing a large amount of carbon dioxide.
Forecasting Eruptions at Restless Calderas
Scientists review decades of data on swarms of earthquakes, surface deformation, degassing, and microgravity changes around calderas to determine when such forms of unrest may result in eruptions.
Hawaii’s Swelling Lava Lake Charts a Volcano’s Hidden Plumbing
Geophysicists used unique seismic signatures to track the cyclic rise and fall of lava inside Hawai'i Volcanoes National Park's Overlook crater.
