Find out how @jinheum.bsky.social, @chslane.bsky.social & colleagues carried out a forensic study of varve sediments from Lake Chala to constrain the season and climatic impact of the 74,000 yr Toba super-eruption 🌋🔬🌏 doi.org/10.1126/scia... [spoiler: it was within background climate variability]

We reveal, at sub-annual resolution, the ~74 ka Toba super-eruption‘s acute, but short-lived impact on eastern African climate using varved sediments in Lake Chala (Kenya/Tanzania)! www.science.org/doi/10.1126/...
Sub-annual resolution evidence for limited impact of the 74-ka Toba eruption on eastern African climate
Sub-annually resolved lake sediments suggest the Toba eruption caused modest cooling and drought in eastern Africa.

Need some motivation finishing up your #tephra paper this summer? 🌋📄 The deadline for submissions for the JQS Tephra Special issue has been extended until September. See more information here… onlinelibrary.wiley.com/page/journal... @cot-iavcei.bsky.social
We report a cryptotephra deposit from a ~120 ka Tondano eruption in a sediment core from Lake Towuti (Indonesia)! doi.org/10.1002/jqs....
Cryptotephra from a ~120 ka Tondano eruption in a sediment core from Lake Towuti (Indonesia)
Southeast Asia is one of the most volcanically active regions in the world, yet their long-term eruptive history has been comparatively little studied. In particular, little work has explored the pot....

Last Tues we were celebrating @jinheum.bsky.social’s PhD viva 🥳 Many thanks to examiners @harrietallengeog.bsky.social @simon-blockley.bsky.social for your wisdom & support. Jinheum also had a paper out [https://doi.org/10.1002/jqs.3730] & starts a postdoc in 2 weeks. Congratulations Jinheum!
It was great to visit Oxford to speak at the seminar in School of Archaeology on Tuesday!
Had a good time in Sicily last week giving a talk + having a day trip to Etna! (thanks to photographers)
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.
Enjoying news from #EGU24. A tad sad not to be in the Cambridge contingent, but cheering them on from home. Check out @jinheum.bsky.social (CL1.2.10 Thurs) on Toba impacts, @yqnatdeng.bsky.social (CL1.2.1, Wed) on lake ecosystem responses to SH westerlies. And… www.geog.cam.ac.uk/events/egu20...
