Matching Magma Dikes May Have Different Flow Patterns

Sarah Stanley, Science Writer by Sarah Stanley 30 April 20255 May 2025

A set of lab experiments involving a laser, gelatin, and xanthan gum explored how varying flow patterns between dikes with similar speeds and shapes could affect eruption predictions.

Martian Magmas Live Long and Prosper

by Mariek E. Schmidt 10 April 20259 April 2025

The depths, longevity, and potential to generate silicic compositions of magma chambers are linked to crustal temperature, which varies across Mars and over its geological history.

Cómo pueden los vulcanólogos mejorar la resiliencia urbana al cambio climático

by Jonathan Fink and Michael Armstrong 27 March 202527 March 2025

Las estrategias pensadas para ciudades enteras para hacer frente al cambio climático pueden beneficiarse de los conocimientos de los vulcanólogos, que llevan mucho tiempo adaptando la información y la comunicación sobre riesgos a las comunidades locales.

The Deep Frontier of Mantle Magma Supply

by Ben Black, Samer Naif, Forrest Horton, Andrea Goltz and Cian Wilson 25 March 202525 March 2025

Compared with crustal magma systems, little is known about the deep sources of volcanic supply chains. Interdisciplinary efforts can help answer key questions about how magma migrates from the mantle.

Water Stored in the Mantle for Millions of Years May Be Linked to Continental Volcanism

by Rebecca Owen 19 March 202519 March 2025

New research shows that intraplate volcanism is more likely to occur over areas of the mantle that are more hydrated—particularly those that have been hydrated for a long, long time.
