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.
Future space missions will further our knowledge of tidal heating and orbital resonances, processes thought to create spectacular volcanism and oceans of magma or water on other worlds.
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.
Magma stored for 1,000 years in an Icelandic volcano journeyed to the surface in just 4 days.
Molecular dynamics calculations suggest that molten hydrogen-bearing iron peroxide (FeO2Hx) may produce the ultra-low velocity zones that occur at the core-mantle boundary.
This former West Point graduate and coffee grower transformed igneous petrology and volcanology.
A synthesis of data from studies in different ocean basins reveals that the characteristics of oceanic crust are shaped by age and spreading rate.
A planned project will drill into a magma reservoir in Iceland that has never erupted to the surface, giving scientists a fresh look at Earth’s underground “plumbing.”
