On my way to Strasbourg, to visit @rocklabstrasbourg.bsky.social and to connect with the @epostcsah.bsky.social community. I got to admit, traveling per train beats the plane by a mile! Better views, better seats, better WiFi. Now if there wouldn't be any strikes on the way... It would be perfect

Big congrats to @claireharnett.bsky.social, who won the 2026 @egu.eu Arne Richter Award for Outstanding Early Career Scientists! 🥳🏅 Here's some photos of Claire recommended by my phone... www.egu.eu/news/1551/eg...

Big congrats to Lucille Carbillet, who won the 2026 @egu.eu EMRP Outstanding Early Career Scientist Award! 🥳🏅 Here's a collection of photos suggested by my phone... www.egu.eu/news/1551/eg...

The ROTTnROCK team mapping hydrothermal alteration at Sulphur Springs in Dominica using a lidar drone! 🌋 @trwalter.bsky.social

ROTTnROCK postdocs Matías and Ariane exploring how hydrothermal alteration shapes volcanic hazards in Dominica 🇩🇲 🌋 @arianeloisel.bsky.social

The ROTTnROCK team investigate Boiling Lake in Dominica! 🇩🇲 🌋 @trwalter.bsky.social @magmatroll.bsky.social @arianeloisel.bsky.social

Some of the ROTTnROCK team are currently in Dominica 🇩🇲 🌋 looking at, well, hydrothermal alteration of course! @magmatroll.bsky.social @trwalter.bsky.social @arianeloisel.bsky.social

New paper out in Solid Earth, led by Sam Thiele: "Hyperspectral mapping of density, porosity, stiffness, and strength in hydrothermally altered volcanic rocks" 🥳 @rottnrock.bsky.social It's #OpenAccess! 👇 se.copernicus.org/articles/16/...

Nice couple of days at Teide volcano summit 🌋 to understand hydrothermal alteration and associated risks with @magmatroll.bsky.social (Uppsala Univ) and @rottnrock.bsky.social ERC synergy grant cc @ipna.csic.es @csic.es

Deadline tomorrow!

Samples of hyaloclastite from Krafla in Iceland 🇮🇸 🌋 These samples are from different depths within the shallow reservoir, and they’re now ready for some physical and mechanical probing in the laboratory!

I'm lurking at the back!

I'm hiring a new post-doc to work on the @rottnrock.bsky.social project! Come help us understand hydrothermal alteration and volcanic hazards! Advert here: www.unistra.fr/universite/t... 📸 Recent ROTTnROCK trip to Mombacho, Nicaragua 🌋

Talking about what laboratory measurements would be needed as part of the FlankEd project in Catania, Italy 🇮🇹 🌋

First day of the FlankEd workshop in Catania! We were all treated to a guided tour of Etna 🌋 by the experts at @ingvterremoti.bsky.social! Here they are pointing at maps at sites of interest!

The science of volcanoes and their relationship with the climate is hard to keep up with. Why do some volcanoes give us little warning before they blow? Are we ignoring the next big eruption?

Doing some Schmidt hammering on the failure surface of the most recent collapse at Galunggung volcano in Indonesia 🌋🇮🇩 These measurements are quick and simple and give us an idea as to the strength of the rock 🪨

Checking out the most recent collapse at Galunggung in Indonesia 🌋🇮🇩 Was quite the mission getting to the failure surface!

Pumice from the 1883 eruption of Krakatau in Indonesia, deposited during one of the most deadly, most destructive, and loudest known eruptions in recorded history 🌋🇮🇩 Feels odd just holding it…

Checking out the new dome at Anak Krakatau from the boat! 🌋🇮🇩🛥️ I spy alteration! 👀

Indonesian volcano themed chocolate complete with volcano-chocolate pun! 🌋🍫

Part of our international team of volcanologists working with @rottnrock.bsky.social! From England, Indonesia, and Chile! 🇬🇧 🇮🇩 🇨🇱 Interesting fact: we all like cats! 🐈

Monitor lizard on the island of Rakata, one of the islands left by the famous 1883 eruption 🌋 🦎

Early morning start for our @rottnrock.bsky.social trip to Anak Krakatau from Anyer 🌋 Our luxury speed boats await! 🛥️ 1/9

Early boat ride to Anak Krakatau tomorrow! 🌋 Quite excited! Although perhaps not looking forward to the boat ride 😂

Obviously, I bought a load of branded merchandise! 🌋

At Galunggung in Indonesia 🇮🇩 🌋 the @rottnrock.bsky.social team were investigating the impressive recent collapse within the crater - we found plenty of altered rocks in the blocky deposit!

The @rottnrock.bsky.social team were at Galunggung today, a volcano famous after a British Airways flight accidentally flew through the huge eruption plume of the 1982 eruption! We’ll go back tomorrow to investigate, collect rocks, and drone the volcano 🌋

Indonesian hot sauce for volcanologists! 🇮🇩🌋🥵

A two part feature! Lectures and scientific discussions today at the Fakultas Teknik Geologi at Universitas Padjadjaran and the Politeknik Geologi & Pertambangan AGP! 🌋 @magmatroll.bsky.social

The @rottnrock.bsky.social team are in Indonesia! 🇮🇩 🌋 we’re here, obviously, to look at the altered volcanoes! 👀 first stop, Tangkuban Perahu in Bandung!

Palagonitised lapilli tuffs from subglacial volcano Cracked Mountain 🌋🇨🇦 line up for physical property measurements in Strasbourg! Will their properties vary as a function of distance from the dyke? 🧐 @alteringrocks.bsky.social

Academia may not give you job security, flexibility, or wealth, but it will let you unexpectedly connect to eduroam in foreign cities

Stunning scenery during helicopter flight from Cracked Mountain 🌋 to Whistler in British Colombia in Canada 🇨🇦 1/3 🚁

For the 50th anniversary of the 1976-1977 eruption of La Soufrière de Guadeloupe, we are pleased to announce the upcoming international conference: Soufrière50: 50 years of volcano science advances fostering resilient futures Guadeloupe – Saint-Claude & Basse-Terre 5–10 July 2026

Flash-back to a few weeks ago when @claireharnett.bsky.social won the @iavcei.bsky.social George Walker Award! 🥇 Congrats again Claire! @farquharson.bsky.social, @alteringrocks.bsky.social, @magmatroll.bsky.social

Lava samples from Mt Etna prepped and ready for KIC measurements at EPFL in Switzerland! 🌋 Project led by Sév Furst at GEOMAR @pre-collapse.bsky.social

Discussing Forchheimer and Klinkenberg corrections for permeability data with @annathrl.bsky.social, who is currently visiting Strasbourg to measure her many dome samples! 🌋 @fabianwadsworth.bsky.social

Volcano thread! 🌋🧵 On the Drake Passage, between the tip of South America and the South Shetland Islands of Antarctica, there is a small island. The island is the caldera of an active volcano, eerily called Deception Island on account of its "outward deceptive appearance as a normal island" 🌋 1/6

Keen to know about hydrothermal sealing and phreatic explosions! Check out our pre-print, led by Sophie Pearson-Grant! 🌋👇 Lots of cool insight from Sophie’s 3D models! www.researchsquare.com/article/rs-6...

#IAVCEI25 @iavcei.bsky.social is now over! 🌋 What a great conference…so many fun and productive science chats! Thanks to @lucacaricchi.bsky.social and the rest of the organization team! Here are some of the (very few) pictures I took during the conference 📸

If you’re interested in hydrothermal sealing and explosions, check out my #IAVCEI25 @iavcei.bsky.social poster today! Number 29! 🌋

New paper in Volcanica looks at the thermal properties of rhyolites from Havre volcano, a submarine volcano in the Kermadec arc (Pacific Ocean)! 🌋 With Rebecca Carey, @smitchellscience.bsky.social, and @fabianwadsworth.bsky.social It's diamond open access 👇 doi.org/10.30909/vol...

@kkamalpha.bsky.social looking for pores with a preferred orientation in lavas in Iceland 🇮🇸 🌋

A selection of waterfalls in Iceland: Goðafoss, Dettifoss, and Selfoss 🇮🇸

Loved puffins since I was little. It’s great to see them! Such clumsy little birds. These ones are nesting on the north coast of Iceland 🇮🇸

Back at the core repository at Húsavík in Iceland 🇮🇸 to look at the shallow geothermal core from the Krafla geothermal reservoir 🌋🏭
