It's even cooler than that, @dbb.bsky.social! That's columnar jointing — it forms when thick lava cools, contracts, and cracks into a pattern of columns perpendicular to the cooling surface. It’s a cooling-related feature rather than flow.

A few days of #volcanology fieldwork in Cabo de Gata (Spain) - great submarine volcanics and a really interesting submarine dome collapse/debris avalanche🌋🌞 @bgs.ac.uk

Cool blog post by @smakris.bsky.social on a super collaborative project to learn more about eruptions and pyroclastic density currents at Volcán de Fuego in Guatemala. Was great to join in the field--now looking forward to helping with paleomagnetic analyses soon! www.bgs.ac.uk/news/fieldwo...

Back from fieldwork in Guatemala looking at PDC deposits from Fuego for our @ukri.org project exploring generation mechanisms. We had a great time in the field as a team bringing together many skills and experiences. Excited to continue working on this also with those who weren’t in the field!

It's my turn in #IAVCEI2025 today! 🌋 I will be presenting a talk on granular flow experiments focusing on PDC processes at 16:00 in room R380.
