A new study sheds light on how magma erodes the conduit it flows through.
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.

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.
