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.

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.
Steam-Driven Blasts Last Seen at Kīlauea in 1924 May Recur
Sinking magma levels and rockfalls prompt warnings, flight restrictions, and the shutdown of Hawai’i Volcanoes National Park.
