The long-period seismicity reveals fluid flow along the caldera fault system, which led to failure and subsequent magma migration. GNSS data indicate no pressurization of a shallow sill following the earthquake, and capture time correlated sill deflation and magma intrusion to the eruptive fissures.

We combined analysis of long-period microseismicity with high-rate GNSS data to study the period between a Mw5.4 earthquake and the onset of magma migration and eruption.

Our understanding of the Universe is stronger because of Bill Nye’s remarkable leadership and advocacy.

Thank you, Bill, for your 15 years leading the Planetary Society, and I look forward to continuing to work with you to advance science and space exploration!🚀✨

In 2025, the AWI and University of Bremen secured extensive data sets from the USA. Now, the @dfg.de has approved around €860,000 in funding to systematically identify endangered data and secure it for the long term with the help of the PANGAEA data platform. ☁️📊

Photo of the Day: The #volcano complex Kaiserstuhl is situated in the south west of Germany near the city of Freiburg. It is one of the most interesting #volcanoes in Germany and for example there are rare rocks similar to the #volcano Ol Doinyno Lengai.

Looking down into a glowing volcanic vent, with a plume of steam and gas rising. All under a cloudy sky with dusk colours.

Red hot lava bombs rise out of a glowing volcanic vent during a loud volcanic explosion!

Still smiling after another amazing visit to Yasur volcano in Vanuatu just over a week ago. We were there to help VMGD install new infrasound microphones in their monitoring network, a vital tool for tracking eruptive activity.

A nice part of Earth (in Canada). A flattish (glacially eroded) small island of granite sits on a still lake reflecting a blue sky dotted with clouds. Two people stand at either end, fishing.

It’s Earth Day, and some of us have spent not just our careers but our whole lives loving + studying the Earth. It is not an easy time. But I hope you take a moment today to look at something beautiful, eat something delicious, squish someone you love, pet a dog, remember the nice parts. Yay Earth.

Jupiter's volcanic moon Io.

Just because.

Two years ago today was one of the most thrilling moments of my life when I captured this sunrise eruption of Guatemala's Volcán de Fuego. My drone was much closer than I realized, and the eruption was the largest I saw in my two days up there. I may never again film something as remarkable as this:

I wonder if this inconvenient (for the fossil fuel industry) plot has something to do with it? 🤔

Notice to flat-Earthers all around the globe: Please alert the authorities if tonight’s Total Lunar Eclipse looks like this:

This was the lava lake in February 2024. We are studying the collapse with @INETER colleagues.

Santiago crater, Masaya caldera, Nicaragua. On March 2, 2024, the south crater wall collapsed (debris cone lower right) burying the lava lake. The shallow magma degassed through two small vents (right center & lower left).
