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🌋🌞

🌋We have a 2.5-years long fully funded Postdoctoral position opened at UoEdinburgh to study volcanic plumes with 3D modelling. Spread the word! elxw.fa.em3.oraclecloud.com/hcmUI/Candid...

Fieldwork on Volcán de Fuego - British Geological Survey Understanding how one of the world’s most active volcanoes builds up material, and how they collapse to feed hot flows

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!

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!

Wrapping up one week of fieldwork at Fuego volcano, flying drones and sampling PDC deposits with @smakris.bsky.social @pdcguy.bsky.social @tyranakisaurus.bsky.social Sylvain Charbonnier, Gustavo Chigna, Fabrizio Ponce, Amilcar Calderas, Edgar Barrios, William Chigna and Mario Ovalle.

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.
