There is not a supervolcano lurking underneath East Anglia. (Before anyone asks 🙄). This is a cool study linking ancient, 454 million year old volcanic rocks under the East of England to ancient 454 million year old ash layers in Scandinavia. You can read the study for free via NORA:

The news about students seeking compensation from universities for COVID teaching has made me quite sad. I can't say what happened at those universities, or what those student's experience was. My present university did not appear to be in the list. But what I can say is...

What happens when a dense, aerated granular flow encounters a vertical barrier? What night these mean for the behaviours of pyroclastic density currents? Check out Jordan Chenery's poster at #IAVCEI2025

We tried compiling a global database of deposit descriptions of pyroclastic density current deposits. The aim was to help us do big data analysis, look for common trends, and to support modelling. We got some interesting results but also, found some really significant issues and gaps #IAVCEI2025

Delighted that this paper has hit p[ublication. Nemi did a truly amazing job on all of this, and together with 3 other papers (1 published 2023, the others winging their way to print soon) has really moved forward our understanding of moisture in pyroclastic sediments.

Day 2: Today we travelled north into Slovakia 🇸🇰 where we observed a basaltic diatreme section and had lots of discussions surrounding maar formation and infill Then we explored a tuff ring with a castle on top! Look at those baked clasts 🌋😍

A group of geologists standing in front of a large (~20 x 12 m) outcrop. The outcrop is beige and grey. On closer inspection the lower ~4 m consists of interbedded layers of lapilli and tuff. These layers are interpreted as maar scoria layers. Above this are two distinct massive units that contain large sandstone clasts with evidence of imbrication.

After this we went to Ipolytarnóc and saw some primary PDCs and some old fossil footprints. Thank you to our amazing and enthusiastic guide! Finally today we went to Tar, where we observed andesitic volcaniclastics and a debris avalanche with some big boulders! 🌋
