Fig. 8 from McLean et al. (2026). Flux of (a) marine diatom taxa Thalassiosira spp. + Cymatotheca (counts/mm2/year) and (b) percentages of Cryptomeria and Quercus-E pollen, recorded in the Lake Suigetsu (SG06) sedimentary sequence. The red dashed line indicates the position of the Aso-3 distal tephra layer (SG14-6662). The green bar marks the interval of laminated sediments corresponding to Marine Isotope Stage (MIS) 5e. Modified from Francke et al. (2025).

🌋 New paper out in QSR!

McLean et al. (2026) shows that the Aso-3 caldera-forming eruption (SW Japan) marks the termination of MIS 6, providing a key tephrochronological marker for correlating East Asian paleoclimate records.

🚨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) 🌋

@danmclean.bsky.social also visited the #LakeSuigetsu Fukui Varve Museum in November to give a guided #tephratastic tour of the layers. 🌋🇯🇵

A photo of Lake Toya - the caldera-forming eruption has been dated using the Lake Suigetsu sedimentary sequence to 108.1 ± 3.9 ka (±1σ)

What have we been up to?💥 Have you seen our recent publications...

Sophie Vineberg and the
#LakeSuigetsu Members have published a new detailed record of Japanese eruptions between 120 - 50 ka🇯🇵, with forty-one crypto/ #tephra layers (!!) characterised and dated 🕰️

It's been a while since I last BlueSkyed (that's the verb, right?)...

...but here's the latest #tephra -tastic offering from the #LakeSuigetsu varved sediments, led by Sophie Vineberg, @volcrocks.bsky.social, @danmclean.bsky.social and other not-yet-BlueSkyers (the noun?)...

So incredibly proud of Dr Charlie Rex, graduating from the University of Glasgow last week, 😊
Congratulations Charlie, you absolute legend!
