I'm giving social media a go after a hiatus, so hi! I'm a Kiwi volcanologist working on Ngāuruhoe (Mt Doom) in NZ, the 2021 La Palma/Tajogaite eruption impacts, seafloor geologic hazards, & collaborate w. @geotenerife.bsky.social. More on my work here: janinekrippner.weebly.com Nice to meet you❤️🌋

Un día como hoy, hace 4 años daba comienzo la erupción del Tajogaite en la isla de La Palma. A las 15.03h (hora local canaria) se iniciaba la erupción, que continuaría durante 85 días hasta el 13 de diciembre, siendo la erupción histórica más larga registrada en la isla y tercera en el archipiélago

Just spent some time digging through old Maxar/DigitalGlobe blogs to find a reference image and found this incredible capture of Mt Fuji. Incredible. The satellite was only three degrees above the horizon when it captured this image. blog.maxar.com/earth-intell...

🌋 Excited to share my new essay in Aeon: one of the most underappreciated global risks isn’t an asteroid or supervolcano—it’s the eruptions we don’t see coming:

MADRID, GRACIAS🇵🇸🇵🇸🇵🇸

Back at home after an incredible week of #fieldwork in La Palma #LaIslaBonita! All lava flows, basalts, phonolites, enclaves of all flavours... learning a lot with the best company, @falladamente.bsky.social @albertocaracciolo.bsky.social and Álvaro! Y mucho #barraquito... ⚒️ 🌋

Return from paradise 🌴🍌🫀🌋 A great fire work is over 😪 #LaPalma #IslaBonitaIslaPreciosa

I'm sure there are deep arguments for either, but I think hauyne is just prettier, which is a consideration when we match up random minerals against one another. ⚒️

Scientists who study climate don't automatically attribute all changes to human activity. Rather, we carefully investigate every possible natural factor that could explain the planet's warming. Could these be the real culprits? The evidence is in--and the answer is NO. This thread explains! 🧵

#Etna 's new lava flow is slowly advancing down the southeast flank of the volcano (currently at about 2400 m elevation), and is accompanied by mild Strombolian activity at the Southeast Crater. Photos taken from Nicolosi, on Etna's south flank, on the evening of 16 August 2025

OBITUARY Jim Lovell, commander of NASA's Apollo 13 moon mission, dies at 97 reut.rs/3UPKubN

Keep sciencing. We are living through a time when looking at a rock and wondering how old it is qualifies as an act of resistance.

54 years ago the Apollo 15 mission was exploring the Hadley Rille area of the rim of the Moon's vast ancient Imbrium Basin. After landing, the 'top' hatch was opened and David Scott obtained panoramas of the surroundings from an elevated view, something done only once. Here is a part of that view.

Two whole days the Kamchatka tsunami has been bouncing around the Pacific!

⚒️ 🧪 A M8.8 earthquake just ruptured the subduction zone offshore Russia’s Kamchatka peninsula. This is one of the world’s truly huge earthquakes, and a triggered tsunami is currently traveling across the Pacific ocean. This same fault ruptured on July 20th in a M7.4, and last August in a M7.1.

The Earthquake Insights article about the Mw8.8 Kamchatka earthquake is, as always, really informative. ⚒️🧪 #geology open.substack.com/pub/earthqua...

Just a reminder that tsunamis aren't just one wave. This tide gauge in Alaska has recorded 5 hours of surges so far from the Kamchatka quake - still more to come!

Working on a project and made this image of the Hunga Tonga volcanic eruption. Never seen it from this perspective and it sort of blew my mind.

📜⚒️🌋 We have a new publication in Volcanica! A robust quantification of H2O in silicate glasses through micro-Raman spectroscopy: insights on the compositional effect. Congrats to Filippo for this great work! www.jvolcanica.org/ojs/index.ph...

Today is the #InternationalMoonDay - marking the 56th anniversary of the Apollo 11 lading... so here goes my last #Moon photo! A crescent Moon HDR composite with Earthshine, 1 May 2025 🔭🌒

Seismometers around the world detected this earthquake. In this animation from @earthscope.org, you can watch the waves sweep across Europe - too small for people to feel, but not too small to be detected by seismic instruments.

⚒️🧪🌋🇮🇸 The fissure slowly extended to the north over the past hours. It is 2.4 km long now, and also extends further north than any of the previous fissures. This new map shows a smaller lava cover area than has been the case in the earlier stages of previous eruptions. www.vedur.is/um-vi/fretti...

Holy shit. This is 3I/ATLAS—the interstellar comet recently discovered passing through the Solar System. You're looking at something that didn't start out here. It came from another star. And, at about 7 billion years old, it was already ancient when our Sun was born.

The fissure of the #Iceland eruption that started this morning is between 700 and 1000 meters long and does not appear to be getting longer. Lava flow appears to be most concentrated to the southeast. No danger for Grindavik so far. ⚒️🧪 #volcano

#Svartsengi #volcano (Reykjanes peninsula): new eruption started - A new eruption has started early this morning on the Reykjanes peninsula. Following an intense earthquake swarm indicating the final push of magma towards the surface from shortly after midnight, an eruptive fissure opened south...

🔔#Earthquake (#terremoto) M5.3 occurred 53 km SE of #Almería (#Spain) 4 min ago (local time 07:13:28). More info at: 📱https://m.emsc.eu/#app 🌐https://m.emsc.eu/?id=1831870 🖥https://www.emsc-csem.org/Earthquake_information/earthquake.php?id=1831870

The AI hype makes doing science so much more difficult. Fighting its nonsense takes time away from doing science and its uncritical adoption hollows out our scientific processes and deskills scientists on a massive scale.

🚨 How far are volcanologists from volcanoes? 🌋🚨 Check out our new paper here: link.springer.com/article/10.1.... What started as a conversation about whether we at @exeter.ac.uk (in Cornwall, UK) are further from volcanoes than our global colleagues turned into an exploration of a fruitful data set!

We are thrilled to announce that the next IAVCEI Scientific Assembly will be held in Costa Rica! 🇨🇷 A heartfelt thank you to everyone who joined us in #IAVCEI2025 in Switzerland. We look forward to seeing you all again in #IAVCEI2029. Welcome to Costa Rica!

🌋⚒️ After one intense werk of volanoes and many friends, #IAVCEI2025 is over! By far the my best conference to date, looking forward the next one. Thanks @iavcei.bsky.social !

Whoa. That's a sprite, an elusive, high-altitude electrical discharge from a thundercloud photographed by NASA astronaut Nichole Ayers from the ISS earlier today. With reported sightings going back more than a century, this phenomenon was first photographed in 1989.

And here we have @albertocaracciolo.bsky.social with his La Palma CPx poster! #IAVCEI2025 🌋⚒️

If you want to learn all about CPx in the 2021 #Tajogaite eruption #LaPalma (including trace element maps!), come to Alberto's poster this afternoonn (no. 242) @albertocaracciolo.bsky.social #IAVCEI2025 🌋⚒️

🌋⚒️Today Jie Wu is talking about our results on the fate of S in the Hunga 2021 eruption, Tonga! Room S150, 11.15 #IAVCEI2025

Huge congrats to Teresa @teresaubide.bsky.social for receiving the Wager medal at #IAVCEI2025! So much deserved! 👏👏👏👏🌋⚒️

Really important point by Blaise Mafuko Nyandwi - do not assume non-experts have no knowledge or expertise of their environment. Fantastic 'Future of Volcanology' talk at #IAVCEI2025.

With a little suspense, but the Geneva volcano finally erupted #IAVCEI2025 🌋⚒️

....and a poster too! Trace element diffusion in tephrite-phonolite couples. Poster board 77. Visit me! #IAVCEI2025 🌋⚒️

First day of #IAVCEI2025! I have a talk on banded pumices from the Tajao ignimbrite in #Tenerife, Canary islands. Room 285, 14.45. 🌋⚒️

Ready for IAVCEI 2025? Let's meet tomorrow at our Tick tick Boom session (1.2)! 🌋 When? 30/06 8:30-10:00 in R280. Poster session: 16:30-18:30 (n°62 to 80). 8:30: Invited talk from E. Mutch. Followed by T. Havard, T. Pereira, A. L Martin, T. Plank, and P. Moreno-Yaeger! @iavcei.bsky.social

Arriving at Geneva #IAVCEI2025 with a spectacular view of Mont Blanc... and the first sign that something is happening ⚒️🌋

⚒️ On my way to #IAVCEI2025 #Geneva! Looking forward to a week of everything volcanoes 🌋and meeting old (and new!) colleagues.

Thank you very much @iavcei.bsky.social and super thank you to my team #UQmagmateam + collaborators + mentors and nominators !! Feeling incredibly honoured and humbled 🤗 Look forward to catching up with the volcano community soon in Geneva!! #IAVCEI2025 ♥️🌋
