Magma Beneath Yellowstone Is Shifting Northeast

by Skyler Ware 31 January 202531 January 2025

Though the volcano’s magma chambers could hold enough material for a caldera-forming event, none of them are likely to erupt soon.

Antarctic Ice Melt May Fuel Eruptions of Hidden Volcanoes

by Madeline Reinsel 3 January 202513 January 2025

More than 100 volcanoes lurk beneath the surface in Antarctica. Ice sheet melt could set them off.

Imaging Magma from Afar

by Peter Zeitler 20 December 202419 December 2024

Reservoirs of magma and fluids in the crust create gravity anomalies detectable by altimetry, which can help find submarine volcanoes and provide key insights into their depth, shape and volume.

Magma Diversity in Iceland

by Peter Zeitler 19 December 202419 December 2024

Iceland’s recent basalt eruptions originated at the crust-mantle boundary and show chemical variability over remarkably short timescales of weeks, suggesting exchanges between diverse magma sources.
