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.

Seismic Images Show Major Change Along the Mid-Atlantic Ridge

by Andrew Frederiksen 7 April 20253 April 2025

New seismic images of the Lucky Strike slow-spreading segment of the Mid-Atlantic Ridge show thick lower crust at the center that thins in both along-ridge directions.

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.

Hawai’i’s Depleted Peridotite Delivers More Magma

by Vincent Salters 24 March 202524 March 2025

The source for the isotopically-enriched Hawaiian magmas contains peridotites that experienced near-surface melting prior incorporation in the plume.

A mostly flat landscape is dotted with mounds, which give way to taller volcanic cones in the background.

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.

Observing Magma-Induced Seismic Velocity Changes with Fiber-Optics

by Marcos Moreno 26 February 202526 February 2025

A new high-resolution method for tracking volcanic activity utilizes fiber-optic sensing to detect magma intrusion by measuring seismic velocity changes.
