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.”

On the Prospect of Ancient Metallic Volcanism on Asteroids
There is a possibility of ancient volcanism on metallic asteroids, a new type of volcanism that is not yet observed, though the Psyche mission to the asteroid Psyche may change that soon.
More Than 30,000 Earthquakes Trace the Movement of Magma
Seismometers near Iceland’s Bárðarbunga volcanic system pinpointed thousands of earthquakes in 2014–2015, revealing where molten rock was moving underground before any eruptions occurred.
Lava Clues Chronicled Kīlauea’s Unusual 2018 Eruption
Samples from Kīlauea volcano’s extraordinary eruption that began last May could offer important insights into the behavior of volcanoes and the underlying mantle.
Carbonate Melting Enhances Mantle CO2 Fluxes in Old Ocean Basins
The amount of CO2 segregated from the mantle by carbonate melting beneath old oceanic crust may equal that emitted along the mid-ocean ridge system, thereby contributing to the global carbon cycle.
Two Active Volcanoes in Japan May Share a Magma Source
Evidence collected following the 2011 eruption of Japan’s Shinmoedake volcano suggests that the powerful event affected the behavior of an active caldera nearby.
Is Mars Not So Earthlike After All?
Light-colored Gale crater rocks could have formed from intraplate volcanoes, not continental crust, new study finds.
Tracing the Steps of Hydrothermal Activity in Hrad Vallis, Mars
Conditions that formed Amazonian age valleys may have been hospitable to microbial life.
Magma Flow in a Major Icelandic Eruption
Mechanical modeling suggests that previous, undetected eruptions released tectonic stress near the ice-covered Bárðarbunga volcano.
Faster Lava Flows, Explosive Eruptions Begin at Kīlauea
Scientists say the dramatic increase in flows is likely due to the arrival of younger, hotter magma in the system.
