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
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
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
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
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
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
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
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.
Etna Under Pressure: Does Gas Buildup Foreshadow Eruption?
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
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.
