First time birding in a long time, got close to four species of water birds: white-cheeked pintail (Anas bahamensis), American Oystercatcher (Haematopus palliatus), possibly a lesser yellowlegs (Tringa flavipes) and a sandpiper (possibly Calidris pusilla)🌿 #birds #birding #guadeloupe #gwada

Pointe des Châteaux, #Guadeloupe #Gwada, French West Indies is the easternmost point of the island of Grande Terre. Early Pleistocene reefs that got uplifted then deeply eroded by the waves of the Atlantic Ocean ⚒️Desirade island in the background

Third phase ot the eruption at #PitondelaFournaise still going strong. It started on April 8 after a few days of quiescence. A new cone is being built next to the main one with lava fountains. @ovpf.bsky.social 🌋⚒️Average 10 m³/s of lava emitted, building a new lava field south of the previous one.

🌋Eruption au Piton de la Fournaise A 9h50, le 2 avril, un nouveau bras de coulée a traversé la RN2, la coupant intégralement en 30 min, à une vitesse de 10 m /heure. ©OVPF-IPGP

This morning a new tongue of the main lava flow from #PitondelaFournaise crossed the coastal road, en route to the ocean. @ovpf.bsky.social measured temperatures as high as 1071 °C🌋⚒️

Eruption at #PitondelaFournaise has restarted, after a three day break! @ovpf.bsky.social webcams show magma in the main cone formed during the previous stage of the eruption🌋⚒️

Eruption at #PitondelaFournaise stopped today, but @ovpf.bsky.social is still not sure yet if this is a temporary break or the end of the eruption🌋⚒️

Beautiful pictures of pahoehoe flows on the delta formed in the ocean by the ongoing ‪eruption at #PitondelaFournaise🌋⚒️ @ovpf.bsky.social Decreasing lava emission rates, but still high seismicity, stable tremor, and the deflation of the edifice stopped.

Ongoing ‪eruption at #PitondelaFournaise: increased lava discharge rate (22 m³/s) at the vent leads to lava fountains, lava delta is growing over the ocean, increased sismicity and significant edifice deflation 🌋⚒️ @ovpf.bsky.social

The coastal lava delta is still growing over the ocean at #PitondelaFournaise. The eruption has now lasted for more than a month (since February 13). @ovpf.bsky.social 🌋⚒️

Lava sampling and temperature measurements yesterday by colleagues from @ovpf.bsky.social on #pitondelafournaise lava flow. Temperature measured at 1130 °C on a pahoehoe flow just before it enters the ocean🌋⚒️

‪Staff @ovpf.bsky.social is in the field sampling lava flows, and measuring temperature and viscocity to better understand the origin of the magma and its rheological behavior 🌋 ⚒️#PitondelaFournaise (and brings us amazing pictures)

Amazing rocks!

Lava flows🌋 ⚒️from Piton de la Fournaise volcano crossing the main road on February 13, covering over 260 m of the road

Yesterday (February 13) around 8 a.m. local time, one of the lava flow from the ongoing eruption🌋⚒️at Piton de la Fournaise volcano crossed the main road and is now 700 m from the ocean www.ipgp.fr/volcanoweb/r...

Spectacular olivine dolerite from Fair Head, County Antrim in XPL for #ThinSectionThursday. Olivine shows particularly vibrant interference colours while the ophitic intergrowth of twinned plagioclase and clinopyroxene is a textbook quality example. 🧪⚒️🌋

🌋 Éruption au #PitondelaFournaise Le champ de lave s’élargit en aval du cône, avec de nouveaux bras de coulée. 🔧 une station de l’OVPF-IPGP à 1,7 km du cône, menacée par les coulées, a été démantelée par une équipe de l'OVPF-IPGP grâce au concours de la SAG et du PGHM.

The eruption🌋 of #PitondelaFournaise that started on February 13 is still active, with a growing cinder cone, and a growing lava flow field.

Little (< 0.3 mm) intercumulus crystals of dalyite (bright interference colours) surrounded by alkali feldspar in a peralkaline syenite. #thinsectionthursday #geology #science #minerals #rocks #microscope #microscopy

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...

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…

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 ⚒️
