A great opportunity to submit a paper to a new joint publication between the AGU and Geological Society: Geohorizons special publication on tephra & hazards. Born our last International tephra meeting, they are still taking submissions! 🧪⚒️🌋 #tephra @geolsoc.bsky.social @agu.org @iavcei.bsky.social

XXII INQUA Congress 2027 in Lucknow, India. Abstract deadline: 15th Feb 2026 COT sponsored session on Tephrochronology across multiple disciplines. Should be fantastic for many tephra fans out there! 🧪⚒️🌋 @oxfordtephra.bsky.social @camtephra.bsky.social @iavcei.bsky.social @inquaecr.bsky.social

We are kicking off some new work in the Northern Cordilleran Volcanic Province this summer we hope! Exciting times, with Shaun leading the way. Some pics from 2021 when we collected the cores presented in the paper 🧪🌋 #fieldwork #geology #tephra

Have a weird urge to write an abstract over Christmas? Tephrochronology Beyond Boundaries: Chronology, Correlation, and Innovation in Earth System Studies Tephrochronology Keynote: Victoria Smith Deadline: 15 Jan 2026, 13:00 CET @oxfordtephra.bsky.social @egu.eu @iavcei.bsky.social

I don't usually do this but if you love nature & quality journalism please donate to The Narwhal. Their work is more important than ever, and are currently trying to raise $200,000 to keep the lights on. You get a charitable receipt, and a donor is matching funds. Please share 🧪⚒️ @thenarwhal.ca

VARG will be there! @hanaayousif.bsky.social @tephrabird.bsky.social I think TIP is going too @tephraportal.bsky.social

🌋 Hello tephra & volcano fans 🌋 We have some announcements, including THREE tephra sessions at the #EGU2026 and TWO special issues! Check out our flyer below with all the details, and pass it on! @egu.eu @ingvterremoti.bsky.social @iavcei.bsky.social @tephraportal.bsky.social 🧪⚒️

Falsifying manifests and locations. Turning off identification systems. Conducting offshore ship-to-ship transfers. This is piracy in the modern era, and Russia is doing all of it to shield its shadow tanker fleet. Writer Wesley Wark investigates: thewalrus.ca/a-ghost-fleet-of...

🚨New paper! Our latest study, led by Sophie Vineberg, integrates proximal & distal tephra records to reveal the timing and dispersal of large explosive eruptions at Aso volcano (Japan) 🌋 🔗 doi.org/10.1016/j.jvolgeores.2025.108436 #tephra #volcanology #Aso #Japan #LakeSuigetsu #tephrochronology

VARGtastic.

Have been laying low, but wanting do something light hearted, I will start sharing my summer for #fieldworkFriday. In May I joined the @iavcei.bsky.social @volc-ice.bsky.social field trip in Iceland. Stunning sunny days the entire time, so I can’t go back 🤣. Ready for future field work in NW BC! ⚒️🧪

Sampling the Logan 2022 ice core for tephra!! 🌋🧊

Pliny the cat with Dawson tephra!!

Next we stop at a favourite: Saskatchewan Crossing. #strataday. Loess, paleosols, and three (!) volcanic ash: Mazama, Mount St Helens Yn and Bridge River. Doesn’t get much better, unless you like glaciers. We finish at Athabasca Glacier. Beautiful but heart breaking in her steady retreat. 🧪⚒️

A reminder that nominations are open for our executive and location for the next meeting. Please email [email protected] if you are interested before May 1st. This is a great opportunity especially for early career researchers- great community and network building! 🧪🌋⚒️

We made it! If you are interested Quaternary geology, archaeology, climate/environmental change and volcanology and how all those things are interconnected by volcanic ejecta, give us a follow. @inquaecr.bsky.social @iavcei.bsky.social @comvolcseds.bsky.social @iavcei-involc.bsky.social 🧪🌋⚒️

CoT is seeking nominations for our executive and hosts for the next Tephra Conference (2028). Interested? Questions? Check out the flyer. Nominations are open until April 30. @iavcei.bsky.social @oxfordtephra.bsky.social @camtephra.bsky.social @tephrotastic.bsky.social @tephraportal.bsky.social 🧪🌋⚒️

New opportunities in Canada 🇨🇦 @oxfordtephra.bsky.social @camtephra.bsky.social @tephraportal.bsky.social @volcancanuck.bsky.social

A few photos from field work in SE Alaska from last year. Taking a hike up Crater Ridge next to Mount Edgecumbe. Almost got lost in the mega-dense fog that didn’t break until we got to the top. What an adventure! #alaska #fieldworkfriday #volcano 🌋⚒️

Tephra Information Portal (TIP) is now on BlueSky Project information at www.iedadata.org/communities/...

Tephra field data workshop at IAVCEI 2025 sa2025.iavceivolcano.org/workshop-12/

We're hiring! Postdoctoral Researcher in tephrochronology-volcanology data management and end-user engagement to join the team working on the FAIR Data Communities – Tephra Information Portal (TIP) project. jobs.concord.edu/postings/3210

To say things are grim right now is an understatement. So we would like to share a bit of fun. In honour of VARG PhD @hanaayousif.bsky.social finally adopting her furry feline, we present "THE CATS OF VARG". We start with the cat of the hour, Pliny! Yes, in honour of Plinian eruptions. #cats 🌋

Cool. Pun intended. Earth, what a planet!

This week, we spoke with the indomitable @katharinehayhoe.com about how climate science got to be so polarized and why she thinks scientists should stop trying to pretend to be neutral when it's our planet at risk. www.cbc.ca/radio/quirks...

How is this even a contest!? Anyone who lives in Edmonton knows magpies rule this city! Whether you love them or hate them. It is the truth. How often do you see a boreal chickadee in the city? Never. Blue jays are good corvids but too Ontario associated. Magpies. Yes. #birds #magpies #YEG

This is a great talk series, people from all over join in thanks to the live stream.

🚨REMINDER: Only 1 day left to submit your abstract! Remember to submit your abstract before: 📅 January 10, 2025 💻 Submission portal : visit our website on-line-form.eu/iavcei2025sa... 📩 Questions regarded to IAVCEI25 please and an email to: [email protected]

Thanks Kevin! Probably should get better at tooting our own horn, haha. Cryptotephra records can tell us a lot (although they are agonizing to build to a critical mass). Shout out to Ali Monteath and co-authors for persevering through years of terrible tiny tephra shards.

From the Dept of Earth and Atmospheric Sciences at the University of Alberta alumni Jessie Reimink and his former supervisor Tom Chacko, nicely posing with the Acasta. Yay!

As a lab account we avoid politics. But we are Canadian and plan on staying that way. @nytimes.com Your headline is pathetic. First, Greenland NEVER belonged to the US. Use your words better! Second, we are sovereign nations and allies. This isn’t “acquiring”. Don’t hide behind placating language.

Great instructors and a STUNNING location. Hard to beat!

Super excited to share our latest on CO2’s role in geological climate change! Using boron isotopes in ~300 million year old brachiopod shells, we show that rising CO2 from volcanic emissions drove a profound change in climate that ended the Late Palaeozoic Ice Age ⚒️🧪🌊 www.nature.com/articles/s41...

Hmmm. Seems appropriate somehow. Start sabbatical in July.

A wonderful tradition for some Canadians of a certain vintage.

I know, I know....I hate to derail your holiday shopping, but you may want to think twice before you buy the 370 square miles of wrapping paper.

If the UCP ever starts to recognize the positive force the UofA is in this province and are able to hire again, I would love to share with the prospectives what a wonderful gift a winter day can be. We are losing them and that is sad. Too many think YEG=Cold=bad. #WinterCity #YEG

Some volcanoes are stealthy. Scientists are trying to find out why. #AGU24

Hello, @agu.org, why not have a "Follow us on Bluesky" image on the landing page for AGU journals? Bluesky, not X, is where 😎 geoscientists hang out. 🧪

Thanks IAVCEI! With AGU next week (without my talk done yet, typical) and end of semester madness makes this a welcome reprieve!

A nice article about the cross-over opportunities between #volcanology and #climate and hazards resilience in the latest @eos.org magazine. eos.org/features/how... PS - @eos.org, please start adding a Bluesky share button to your pubs!

I will never, ever get over this.

Get ready for IAVCEI2025! In the next summer, we are bringing you 7 major themes, 66 exciting sessions, plus, 15 incredible workshops. All in Geneva, Switzerland! 📅 Register now and be part of it! 🌎 For more information, please visit: sa2025.iavceivolcano.org

The place we were born! If you want to live in the clouds part time and work with some great people, SFU Earth Sciences is definitely worth joining. The great view of Mount Baker going up and down the mountain doesn’t hurt either 🌋
