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

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!

Come join us!

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

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

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 🌋

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!

Plenty of altered lapilli tuffs on Cracked Mountain! 🌋🇨🇦

@rottnrock.bsky.social PI @claireharnett.bsky.social receiving the George Walker award! 🥳 @iavcei.bsky.social

Altered lapilli tuffs! 😍

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...

Collection of great talks about phreatic explosions and hydrothermal sealing! 🌋 John Stix, Maarten de Moor, Emily Mick, Geoff Kilgour, Jessica Salas Navarro…

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

Bubbling mud pools at Hverir/Námafjall in Iceland 🇮🇸 Blubb blubb

Cristobalite and diktytaxitic textures are common in lavas. Do they influence rock properties? We try to answer this question by measuring rocks from submarine volcano Havre 🌋 With @smitchellscience.bsky.social, Rebecca Carey, @alteringrocks.bsky.social It's open access 👇 doi.org/10.1016/j.jv...

ROTTnROCK PI @claireharnett.bsky.social wins the @iavcei.bsky.social George Walker Award! 🥇 Congratulations! 🥳

🚂🌱 On the train journey back from Sweden 🇸🇪 to Strasbourg 🇫🇷 after a fantastisk ROTTnROCK annual general assembly, filled with inspiring talks 🌋. Huge thanks to the Uppsala team (@magmatroll.bsky.social) for the top-notch organisation 💯 @rottnrock.bsky.social @rocklabstrasbourg.bsky.social

@arianeloisel.bsky.social and Ben De Jarnatt present the recent Mombacho 🌋🇳🇮 to the rest of the ROTTnROCK team! It was a great trip and we’re all very excited about the data!

The ROTTnROCK general assembly in Sweden 🇸🇪 has now come to a close! Amazing few days discussing all things rotten, and at a great location! @magmatroll.bsky.social @rocklabstrasbourg.bsky.social @claireharnett.bsky.social @trwalter.bsky.social Next one to be held in Strasbourg! 🇫🇷

The annual ROTTnROCK general meeting continues today with more talks from the wider team! Lots of rotten rocks! 🌋🌋🌋 @arianeloisel.bsky.social @magmatroll.bsky.social @claireharnett.bsky.social @rocklabstrasbourg.bsky.social @trwalter.bsky.social

The ROTTnROCK annual general meeting is underway at Krusenberg Herrgård in Sweden 🇸🇪 organised by @magmatroll.bsky.social and team. The first day included overview talks from all the PIs @rocklabstrasbourg.bsky.social @trwalter.bsky.social @rocklabstrasbourg.bsky.social @magmatroll.bsky.social

Pre-print "Hyperspectral mapping of density, porosity, stiffness, and strength in hydrothermally altered volcanic rocks" now available for comments! 🌋 @rottnrock.bsky.social egusphere.copernicus.org/preprints/20...

Ariane @arianeloisel.bsky.social and Alex @alteringrocks.bsky.social exploring the active fumarolic activity at Mombacho volcano in Nicaragua 🌋🇳🇮 @rottnrock.bsky.social

The amphitheater of Mombacho volcano 🌋 is certainly impressive! Current focus of the surface manifestation of hydrothermal activity is very localized. We’re here with INETER to explore 🌋🇳🇮 @rocklabstrasbourg.bsky.social @arianeloisel.bsky.social

The alteration at Mombacho volcano 🌋 🇳🇮 has recently killed the trees at the top and sides of the scarp. Working with INETER, we plan to map the extent of the alteration @rottnrock.bsky.social

Sometimes, as a supervisor, you just need to hold the umbrella ☂️ protecting Ben from the sun as he maps the alteration at Mombacho volcano 🌋 🇳🇮 @rottnrock.bsky.social

The @rottnrock.bsky.social team arrive at Mombacho volcano 🌋 in Nicaragua 🇳🇮 to work with INETER to try to understand how alteration is influencing the volcano @rocklabstrasbourg.bsky.social @arianeloisel.bsky.social

Ben De Jarnatt droning Mombacho in style! We’re in Nicaragua to work with INETER to understand the extent of the hydrothermal alteration at Mombacho volcano 🌋🇳🇮

The @rottnrock.bsky.social team were at INETER yesterday, explaining the project and discussing how we can jointly help better understand Nicaraguan volcanoes, particularly Mombacho 🌋🇳🇮
