It was fantastic to host more than 160 delegates to the Volcanic and Magmatic Studies Group (VMSG) Annual meeting at our Southampton site last week! 🌋🌊

Check out this really great insight into work on board a research vessel and why you should care about hydrothermal systems in volcanoes by @sofiadellasala.bsky.social onboard the @ukri.org vessel RRS Discovery for the NERC funded HYRDOMOX project led by @noc.ac.uk m.youtube.com/watch?v=leZ7...

We at @noc.ac.uk are very excited to be hosting the VMSG Annual Meeting which kicks off today with a session on marine volcanism following a morning of fantastic workshops.

What a cracking first day of science presentations at the @vmsg.bsky.social Annual Meeting at @noc.ac.uk Fascinating talks and posters across the sessions. Back today covering magma, eruptive processes and volcanic monitoring among other topics. Photos taken by Dan Bourne.

The end of a great @vmsg.bsky.social Annual Meeting hosted by @noc.ac.uk. Two and a half days of high quality science and still one more workshop to look forwards to tomorrow on pyroclastic stratigraphies led by @volcanologist.bsky.social @pyroclasticpete.bsky.social @drnatashadowey.bsky.social

Huge congratulations to Jacob Nash from @noc.ac.uk on winning the Bob Hunter Prize for Best Student Oral Presentation at the @vmsg.bsky.social Annual Meeting. Very well deserved and stay tuned for his soon to be published paper on the marine deposits of the Hunga Volcano eruption.

There is still time for submit an abstract and register for the Volcanic and Magmatic Studies Group (VMSG) annual conference at the National Oceanography Centre Southampton in January next year. The deadline has been extended to Friday 5th December. noc-events.co.uk/VMSG-volcani...

Was great to spend a day with INGV looking at lahar and debris avalanche deposits on the slopes of Mt Etna and discussing land to ocean transport processes. Really inspiring to see these deposits in the field with local experts!

Isobel Yeo@isobelyeo.bsky.social · 10mo ago

The best thing about this job is that you get to keep learning. Absolutely incredible day looking at landslide and lahar deposits off Etna with amazing INGV scientists and @mikeaclare.bsky.social (who always teaches me things I don’t know about sediments).

Great to see @mikeaclare.bsky.social @noc.ac.uk quoted in this piece in the Guardian today www.theguardian.com/news/2025/se... about the Hunga Volcano eruption and the subsequent telecommunications outage in 2022.

Awesome fieldwork in the UK Lake District seeing welded ignimbrites, subaqueous volcaniclastic density current deposits, autobreccias & lots of soft sediment deformation in and around ancient caldera fill sequences. Scoping future ideas with @isobelyeo.bsky.social @noc.ac.uk @vmsg.bsky.social

Amazing talk by @isobelyeo.bsky.social bringing together loads of collaborative research on volcanic hazards from the 2022 Hunga eruption and what we can tell from the deposits left behind at @iavcei.bsky.social @ukri.org

A really great end to this lahars focussed mini session at @iavcei.bsky.social by @mikeaclare.bsky.social from @noc.ac.uk presenting work on lahars offshore and their huge sediment loads funded by the Sustainable Blue Economies Program.
