Unusual feature at Piton de la Fournaise: a small pyroclastic flow likely caused by collapse of an old cinder cone occured at 14:00 local time on February 15, 2026🌋⚒️

Second eruption of the year at Piton de la Fournaise started on February 13, 2026, with initially four fissures (only one active now), and a lava flow going towards the ocean (stopped now) 🌋⚒️

📖 Retour sur l'éruption du 18-20 janvier 2026 au #PitondelaFournaise dans le dernier bulletin mensuel de l'OVPF-IPGP Quelques chiffres: - 830 séismes VT - Jusqu'à 60 cm de déformation - 0,88 million m³ de lave émis Toutes les infos ici👇 🇫🇷 www.ipgp.fr/volcanoweb/r... 🇬🇧 www.ipgp.fr/volcanoweb/r...

After 2.5 years of quiescence, eruptive activity restarted at Piton de la Fournaise on January 18-20, 2026 with a short eruption🌋⚒️

🌋 Retour en images sur l’activité explosive observée à proximité du site éruptif. Le 15/02/2026 vers 14h, l’effondrement d’un ancien cône en aval de l'éruption a généré de petites coulées de type pyroclastique. Analyse détaillée dans notre communiqué 👇 www.ipgp.fr/volcanoweb/r... 📸 Clément Dijoux

Haüyne is gorgeous!!!

▶️ Communiqué OVPF-IPGP - 30/11/2025 . L'activité sismique sous le Piton de la Fournaise se poursuit. . Une légère inflation semble se dessiner. . De faibles concentrations de SO2 et de H2S, associées à une augmentation de H2O, sont enregistrées. Toutes les infos ici 👇 www.ipgp.fr/volcanoweb/r...

@erikklemetti.bsky.social @olamb245.bsky.social looks like there is indeed a lower part of the plume that moved to a different direction

Do you like stripy rocks? Want to study how ore deposits form? Does fieldwork in Norway sound like fun? Come do a PhD with @3oja.bsky.social and me (and a few others) at @ueaenv.bsky.social! aries-dtp.ac.uk/studentships...

▶️ Les équipes du REVOSIMA étaient présentes ce matin, place de la république à Mamoudzou, pour la journée nationale de la résilience. L'occasion pour la population de s'acculturer aux risques et plus particulièrement aux risques volcaniques et sismiques 🌋.

No seriously, the reason to vote for haüyne is that it's the absolute bluest thing--it is the super expensive blue that traditional aquamarine paint was made from (lazurite per MinDat when analyzed is just a variety of haüyne).

For my American friends…

▶️ La campagne en mer MAYOBS33 aura lieu du 25/09 au 14/10/2025 à bord du Marion Dufresne. Cette mission s'inscrit dans le cadre des campagnes océanographiques de surveillance du REVOSIMA. Plus d'informations ici👇 @ipgp.bsky.social @brgm.fr @cnrs-insu.bsky.social @ifremer.bsky.social

An unexpected discovery of IODP Exp 398! 200 m of ash from the Kos Plateau Tuff eruption buried in the basins around Santorini, read how it got there in our new paper in Science Advances 🌋 www.science.org/doi/10.1126/...

We tried compiling a global database of deposit descriptions of pyroclastic density current deposits. The aim was to help us do big data analysis, look for common trends, and to support modelling. We got some interesting results but also, found some really significant issues and gaps #IAVCEI2025

What happens when a dense, aerated granular flow encounters a vertical barrier? What night these mean for the behaviours of pyroclastic density currents? Check out Jordan Chenery's poster at #IAVCEI2025

hello hi i am presenting a poster #IAVCEI2025 (session 3.4) on long-lasting ashy rhyolite eruptions esp. in Iceland, come chat come come

Poster board 165 today at #IAVCEI2025 ! Come see my ongoing PhD research project 🪨

My poster is up at #IAVCEI2025! Come through and get a free sticker while you learn about the US’s new IHPV #forceasu @forcehighp.bsky.social @iavcei.bsky.social

Come and see my poster today at #IAVCEI2025 if you love field volcanology and pyroclastic density currents

Still not in Geneva today 😒 #IAVCEI2025 but if you are interested in volcanic textures and highly explosive basaltic eruptions please go to poster board 97 tonight to see Lisa's work on the 8600 BP subplinian eruption of La Vache and Lassolas in the French Chaîne des Puys 🌋

Unfortunately I cannot be at #IAVCEI2025 today, but for people interested in olivine diffusion chronometry, please come see our posters 62 (Mayotte, presented by Kalini) and 65 (Ambae, Vanuatu, presented by Eva)🌋

Structural geology fieldcamp for the finishing undergraduate students on beautiful Cap de Creus (with @caroline-lotout.bsky.social and Valérie Bosse). Starting with folding and bedding/cleavage relationships in a very low-grade greso-pelitic series.

Today I was teaching binary phase diagrams with a solvus to undergrads so here is a pretty perthite with a Carlsbad twin from the hypersolvus Tolla granite (Corsica) for #ThinSectionThursday ⚒️

Hi @earth-science.bsky.social can you add me to the feed please? Thanks! Etienne

For #VolcanoMonday, I give you Manaro Voui volcano, a shield volcano on the Island of #Ambae in the #Vanuatu arc. A poorly known volcano, it flew under the radar until unrest started in the 1990s, culminating in a major eruption in 2017-2018 that lead twice to the evacuation of the entire island.⚒️🧪🌋

'tis the season for ice crystals ⚒️ #mineralogy #minerals #geology

Short introduction since I have not yet been really active here. Igneous petrologist working mostly on volcanic rocks using field, analytical, and experimental tools. Also teaching (faculty at Université Clermont Auvergne). Interested in anything linked to nature: mineral, plant, animal, landscape

Watch these snowflake-like dendritic clinopyroxenes twinkle as this thin section is rotated in cross-polarised light!❄️☃️ This is a rare volcanic rock called komatiite, from Gorgona. Credit: Charlie Gordon. #ThinSectionTuesday #Petrology #Mineralogy

First day of our undergraduate fieldcamp looking at deformation and metamorphism on the beautiful Cap_de_Creus - deformation in a low-grade gresopelitic sequence and relationships between bedding and schistosity (Cadaques)

Cephalanthera damasonium on (wet) limestone soils in the southern part of the French Massif Central #orchids

The second PhD paper by our amazing PhD student Pauline Verdurme is online! Read for free at authors.elsevier.com/c/1izOE,Ig4Y... for the next 50 days about what vesicles can tell us about the 2018-2020 large submarine eruption offshore Mayotte. #earth-science @earth-science.bsky.social

First few #orchids of the season on a sunny limestone slope (likely Anacamptis morio) #botany #wildflowers

First mushroom of the year 😋
