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.

Gas-Rich, Transcrustal Magma Storage in the Main Ethiopian Rift
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.
New Evidence of a Giant Lava Lamp Beneath the Ancient Pacific
Seismic surveys find evidence of a superplume in Earth’s mantle that fueled ancient megaeruptions in the Pacific.
Are Geysers a Signal of Magma Intrusion Under Yellowstone?
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?
Fault Dips Figured in Kīlauea’s Caldera Collapse
Large-volume volcanic eruptions can create instabilities in the ground above magma chambers, leading to massive collapses and telltale calderas.
Using Garnets to Explore Arc Magma Oxidation
Samples collected from Greece help researchers piece together a scientific puzzle.
Does Io Have a Magma Ocean?
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.
Explosive Volcanic Eruption Powered by Water-Saturated Magma
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.
Crystal Clocks Serve as Stopwatch for Magma Storage and Travel Times
Magma stored for 1,000 years in an Icelandic volcano journeyed to the surface in just 4 days.
The Lower Mantle May Have a Wet Bottom
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.
