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...
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.
If you’re interested in knowing more about our work in Santorini here is me talking for two and a half minutes about what we’ve been doing and hope to achieve. Put together by our magnificent Comms Team and filmed by the brilliant Dan Bourne. m.youtube.com/watch?v=6jFc... @noc.ac.uk @ukri.org

@comvolcseds.bsky.social @iavcei.bsky.social
@smakris.bsky.social and I will present tomorrow as part of the @vmsg.bsky.social 60th Anniversary series. I'll give an overview of the @gcrf-ixchel.bsky.social project and some work at Fuego #volcano, and Symeon will discuss perched tephra piles and granular flows.
