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! 🌋🇨🇦

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...

Steamy! Active fumaroles at Mombacho volcano in Nicaragua 🌋🇳🇮

Ariane Loisel @arianeloisel.bsky.social testing the strength of the outcrops at Mombacho 🌋🇳🇮 we aim to make a 3D model of the volcano to investigate stability @claireharnett.bsky.social

Mike Heap @rocklabstrasbourg.bsky.social, Ben De Jarnatt, and Ariane Loisel @arianeloisel.bsky.social on the flanks of Mombacho volcano 🌋 🇳🇮 We are working with INETER to try to better understand the hazards posed by the volcano

Hot hot hot! 🥵 Active fumaroles at Mombacho volcano in Nicaragua 🌋🇳🇮

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 🌋🇳🇮

Congratulations to Agata Poganj, who published her first paper "Spatial distribution of alteration and strength in a lava dome: Implications for large-scale volcano stability modelling"! 🥳 🌋 @rottnrock.bsky.social Check it out here 👇 doi.org/10.1016/j.jv...

😍

Amazing altered samples from Las Cañadas caldera in Tenerife! 🌋🤩 @rottnrock.bsky.social @trwalter.bsky.social @magmatroll.bsky.social @claireharnett.bsky.social

Meet Benjamin De Jarnatt, our ECR of the month!! Originally from the United States 🇺🇸, Benjamin left behind the waves of Santa Cruz and now calls Germany 🇩🇪 home sweet home, where he's diving deep into the world of geosciences. Read his story 👇

Productive week of back-to-back seminars at Université de Genève 🇨🇭 and Université de Lausanne 🇨🇭, about the influence of hydrothermal alteration on volcanic hazards 🌋 and @rottnrock.bsky.social! Lots of interesting science discussions! Thanks to @lucacaricchi.bsky.social and @anungsamsu.bsky.social!

The fluctuating hydrothermal activity at Lastarria follows a systematic pattern, with changes first seen at the summit before spreading to the flanks, as our latest work shows. Check it out here: authors.elsevier.com/sd/article/S... @rottnrock.bsky.social

Glad to inform that our new paper about detecting hydrothermal deposits using the GEE platform is out. We even can identify a sulfur flow from space! Check it out here: authors.elsevier.com/sd/article/S... @rottnrock.bsky.social
