A new analysis suggests that a widely accepted approximation of ancient magnetic field strength may be less accurate for the past 5 million years than previously thought.
New research shows that huge bubbles can change the viscosity of lava and drastically affect how it moves across the landscape.
Combining commercial hydrocarbon and mineral exploration data with novel academic research and modeling capabilities helps answer key questions about underground magma systems.
Researchers suggest a magma chamber sits within an old submarine caldera structure that extends into the mantle. Nearby, a new underwater volcano emerged with a flurry of seismicity.
At Kīlauea Volcano, scientists are using unoccupied aircraft to monitor the new water lake, a possible harbinger of explosive activity, that formed after the volcano’s 2018 eruption.
Increments of melt trapped in crystals reveal upper crustal magmas in the Main Ethiopian Rift are rich in water and other volatiles, leading to extensive diffuse degassing and hydrothermal systems.
Seismic surveys find evidence of a superplume in Earth’s mantle that fueled ancient megaeruptions in the Pacific.
Steamboat Geyser, the world’s tallest, is in the midst of one of its largest periods of activity. Is it linked to new magma intruding under the Yellowstone caldera?
Large-volume volcanic eruptions can create instabilities in the ground above magma chambers, leading to massive collapses and telltale calderas.
Samples collected from Greece help researchers piece together a scientific puzzle.
