Hundreds of Volcanic Explosions Detected Underwater at Kīlauea

Jenessa Duncombe, Staff Writer by Jenessa Duncombe 14 December 202120 December 2021

Hundreds of volcanic explosions detected underwater at Kīlauea
The explosions, identified during the 2018 eruption phase, offer a clear acoustic signal that researchers could use to measure ocean properties.

How the Armero Tragedy Changed Volcanology in Colombia

by Santiago Flórez and Camilo Garzón 30 November 202128 March 2023

The deadly eruption of Nevado del Ruiz in 1985 made Colombian volcanologists realize that studying natural phenomena was irrelevant if they could not share their knowledge to avoid predictable tragedies.

Identifying an Eruption “Tipping Point” in Hot Spot Volcanoes

Kate Wheeling, freelance science writer by Kate Wheeling 15 November 20211 August 2022

By analyzing lava samples, researchers show how chemical processes that occur during magma’s ascent to the surface may contribute to a volcano’s eruptible state.

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.

Supergreen Trees Can Signal Sites of Eruptions

by J. Besl 8 November 202126 April 2022

Tree core chemistry can explain what happened before Mount Etna’s 2002 eruption and suggests that trees could play a role in rebuilding past eruptions.

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.

Climate Change Will Alter Cooling Effects of Volcanic Eruptions

by Michael Allen 20 September 202114 April 2022

New research indicates the cooling effect of rare, large eruptions will increase, whereas the effects of more frequent, smaller eruptions will be reduced.

Is Venus Volcanically Active? New Approach Could Provide an Answer

Sarah Stanley, Science Writer by Sarah Stanley 15 September 20218 February 2022

A strategy that combines geologic mapping with data on how the planet’s surface emits and absorbs microwave radiation could potentially identify recent lava flows.

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.

The Understudied Risks of Low-Magnitude Eruptions

Kate Wheeling, freelance science writer by Kate Wheeling 14 September 202129 March 2023

Volcanologists have historically focused on the risks of large-scale eruptions, but new research highlights how small eruptions can combine with human-made vulnerabilities to cause catastrophic impacts.
