This looks exciting - a new scanning method to detect tephra 👌🌋🧪🔬

Just going to repost this - EGU is looking pretty special this year, especially for the tephra fans out there! #geology #volcano #tephra #egu2026 @egu.eu @iavcei.bsky.social 🌋🧪⚒️

What’s the collective noun for a cluster of geographers rarely seen out of the labs? Seasons Greetings from Cambridge everyone! 🎄✨🎄✨🎄✨🎄 @camunigeography.bsky.social

Stunning footage from earlier today, when the new Kilauea eruption covered the USGS Webcam 3, which is situated in the Halemaʻumaʻu crater near the southern rim of the much larger Kilauea caldera. This *isn't* what the people of Pompeii saw. But it's not very far off.

Not all tephra travels by air…

Pumice rafts are floating mats of volcanic rock from the eruption of underwater or coastal volcanoes. Monteath et al., analyze the chemistry of pumice from the Falkland Islands and trace its origin from ∼20,000 km away in the South Sandwich Islands 🌊 agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Here is a hastily constructed animated gif from different NASA satellites showing the progression of the Hayli Gubbi eruption. Note the tall ash plume spreading NE (right) and a lower, light tan ash flow(?) moving NNW. #eruption #volcano

Two weeks until our 2/12 PhD funding deadline! If you’re interested in a cryptotephra research project and joining @camtephra.bsky.social there’s still time drop me an email to discuss your ideas. Dept funding info: www.geog.cam.ac.uk/postgraduate... NERC DLA: nercdtp.esc.cam.ac.uk/StaffDirecto...

Cambridge Tephra Lab paper hot off the press: read how (2022-23 masters student) @elowilkinsonrowe.bsky.social used tephra layers in lakes to reconstruct Holocene explosive eruptions from the Main Ethiopian Rift. #tephratastic www.sciencedirect.com/science/arti...

~100,000 years of rainfall… 💦

🚨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

Another reason to ♥️ volcanic ash

Wonderful tephra layer revealed in this peat core sample. Follow the thread to find out where from… 🌋✨

Dept of Geography's Prof Christine Lane @chslane.bsky.social was at the Romanian Academy, Cluj, for the "Integrating ice core, marine & terrestrial environments" network meeting. The two-day event was a great success, with current and former @camtephra.bsky.social members presenting their research.

Last week PhD student @yqnatdeng.bsky.social and @chslane.bsky.social were sampling cores from an Ethiopian lake…in Aberystwyth! Here’s hoping there’s lots of ancient cryptotephra to be found! #tephratastic

🌋📢 Calling all #tephra researchers! Join us in shaping this new JQS Special Issue. "Beyond the #Eruption – Advances and Applications in Distal Tephra Analysis Across the Geosciences" Deadline: 2 Jan 2026. Further details below: onlinelibrary.wiley.com/page/journal...

We’ve had two days of science in beautiful Cluj as the “Integrating ice core, marine & terrestrial environments” network met for an open meeting. Photos of past/present @camtephra.bsky.social members presenting their work and the birthday flowers they embarrassed me with. @jinheum.bsky.social

LST floating in LST. Small pleasures 🤓🌋 (Laacher See Tephra floating in the heavy liquid, lithium metatungstate)

Volcanic ash originating from Russia’s Kamchatka Peninsula canceled Alaska Airlines flights to Nome and Kotzebue Tuesday morning. The ash plume came from the Klyuchevskoy volcano, prompting an advisory from the Alaska Volcanic Ash Advisory Center.

We report a cryptotephra deposit from a ~120 ka Tondano eruption in a sediment core from Lake Towuti (Indonesia)! doi.org/10.1002/jqs....

Some nice fresh looking tephra from Laki. Imagine these fragments quenching in fire fountains a kilometer high

🌋 Lewotobi Laki-laki volcano is at it again. Biggest hazards are lahars and volcanic ash (the latter being particularly bad for air traffic). Stay safe, Indonesians! www.bbc.com/news/article...

Cambridge tephrochronologists discover Holocene wall art from the “other place”… 👀 Come visit anytime @oxfordtephra.bsky.social

Megadrought Reveals Volcanic Ash at Lake Mead Volcanic ash from volcanoes in Wyoming, Idaho, and California was deposited in the rocks along the shore. The ash samples ranged from 6 million to 12 million years old. #drought #LakeMead 🧪 www.discovermagazine.com/planet-earth...

Thanks to Alex Mattin [ www.wgtn.ac.nz/antarctic/ab... ] for visiting yesterday and giving a fascinating talk about his search for tephra from the ~25 kyr Ōruanui eruption in Antarctic ice cores!

Congrats! But we will miss you @jinheum.bsky.social 😭

Welcome home, my beloveds, to #FossilFriday 🧪⚒️. I've spent most of the week deep in the collection, trying to get a basic count together as we look at moving to a new home. Sometimes you find things you never realized were there all along. Here, plant fossils from the Florissant Fm.

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

Our good old friend the Laacher See Tephra in a speleothem! #tephratastic @swinnyy.bsky.social

This is wonderful footage. Enjoy

The Cambridge Tephra Lab wishes you all a Tephratastic new year!

Sediment sending me some love while sieving for #tephra 🤎🥺

It was great to visit Oxford to speak at the seminar in School of Archaeology on Tuesday!

What a view that is @palaeobecca.bsky.social 🤩 Looking forward to many more shots of your field and lab work!

From one volcanic ash lab to another, welcome to Bluesky @tephrotastic.bsky.social 🌋⚒️ I’ll show you mine, you show me yours 😉 …Here’s a close up of a beautiful microvesicular glass shard from the ~8 kyr BP Mercato tephra, sampled near Naples 🤩

Given the new followers👋 I’ll reintroduce myself: I use volcanic ash to date sediments hiding secrets of past climates & people. Prof in Cambridge Uni Geography & Corpus Christi College. Likes: field & lab teaching, tephra-hunting, family time. Follow my group @camtephra.bsky.social Now your turn…

Wow, hello new people! This is a weird, sad, scary time, but welcome & I hope you'll stay a while. I mostly post about science and I lean toward the strange stuff. Speaking of which, do you like trilobites? Here are some that were smothered in volcanic ash & preserved in 3D, 515 million years ago 🧪

Calling all researchers in tephra studies and volcanology! Join us at #PAGES25 for an engaging session on advancing tephra/volcanology research. Share your work and contribute to discussions either on site or remotely. Abstract deadline: 1st December. www.pages2025.org.cn/Data/List/Ab...

Absolutely beautiful rocks and plants

Some lovely Cambridge Tephra Lab news!

#WorldRhinoDay Deadly ash from a supervolcano millions of yrs ago killed almost everything in its path, leaving hundreds of well-preserved fossils in NE, including rhinos (Teleoceros major), horses, camels, & saber-toothed deer. arstechnica.com/science/2024...

Had a good time in Sicily last week giving a talk + having a day trip to Etna! (thanks to photographers)

Huge shout out to the COT24Early Career Presentation prize winners and runners up. Including Elo Wilkinson-Rowe, who presented about her MPhil research, completed in the Cambridge Tephra Lab last year. 🌋⚒️

Documenting this day so we can attribute all the Mt Etna tephra we are about to find in our cryptotephra lab to the correct isochron 🫣🌋🤔🕵🏻‍♀️ #tephratastic #toomuchtephra ⚒️

Members of the Cambridge Tephra Lab (past and present) are at the Commission of Tephrochronology meeting, Catania - COT24, this week.

Job alert! A chance to work with the incredible Matthew Adeleye on his project “Integrating past and present ecologies, and traditional knowledge for effective biodiversity management into the future”. Please share with your networks! #geosky www.jobs.cam.ac.uk/job/48010/
