La vida después de una super erupción

by Danielle Beurteaux 9 November 202116 March 2022

Una vez que una erupción volcánica masiva termina, el sistema subyacente puede mantenerse activo por miles de años. Una nueva investigación vislumbra cómo funcionan los ciclos de super erupciones.

Life After a Supereruption

by Danielle Beurteaux 27 October 202116 March 2022

Once a massive volcanic eruption is finished, the underlying system can remain active for thousands of years. New research illuminates how supereruption cycles work.

Earthly Lava Tubes May Offer Insights into Extraterrestrial Life

Aaron Sidder, freelance science writer by Aaron Sidder 21 September 202118 January 2022

New research finds that Actinobacteria in lava caves fix carbon and survive independent of surface inputs, offering a fresh perspective in the search for life beyond Earth.

A Novel Thermobarometer to Infer Mantle Melting Conditions

by Susanne Straub 16 September 20214 August 2023

The algorithm RevPET automatically reverses the complex multi-phase fractional crystallization path of oceanic basalts and offers new perspectives for advancing mantle thermobarometry.

Mount Etna, a stratovolcano, sits in front of an ashy night sky. Lava erupts from and flows down the volcano, and ash and gas billow up from a vent behind the peak and make the sky glow orange. A few star trails appear in the upper right corner.

Etna Under Pressure: Does Gas Buildup Foreshadow Eruption?

Kimberly M. S. Cartier, News Writing and Production Intern for Eos.org by Kimberly M. S. Cartier 15 September 202129 March 2023

Pressure from both magma and gas can trigger eruptions. Monitoring degassing can help predict eruptions but only if the magma system is well understood first.

Coupled Mechanisms of Fluid Transport Across the Crust

by Beatriz Quintal 14 September 202111 May 2022

Magmatic fluid moves up in the ductile zone through porosity waves, accumulates in high-porosity lenses, and migrates across the brittle zone in a convection pattern involving also meteoric fluid.

Lava from Bali Volcanoes Offers Window into Earth’s Mantle

Jon Kelvey, Science Writer by Jon Kelvey 13 August 20214 August 2023

Lava from the Agung and Batur volcanoes provides a near-pristine picture of Earth’s mantle and raises questions about all volcanoes along the Indonesian Sunda Arc and beyond.

Persiguiendo magma por la península de Reykjanes en Islandia

by Alka Tripathy-Lang 30 June 202119 July 2023

La Oficina Meteorológica de Islandia ha estado rastreando la agitación cerca de la erupción de Fagradalsfjall desde diciembre de 2019, mientras que investigadores en otros lugares exploran nuevos métodos para ver los enjambres sísmicos de Islandia.

Magma Pockets Lie Stacked Beneath Juan de Fuca Ridge

Sarah Stanley, Science Writer by Sarah Stanley 14 June 202127 October 2021

Analysis of new imaging data suggests that vertically stacked magma chambers are short-lived and contribute to eruptions.
