And probably cost the best part of £200 for the pleasure...? 🙈

Annie manually read & classified 7000+ Facebook posts to assess how community use of a local Facebook group can inform on changes in social behaviour & emotional response during a highly destructive volcanic eruption!

There are some surprising results!

This new works extends my own work from back in 2014 where we did a similar thing, but with much simpler Finite Element models: www.sciencedirect.com/science/arti...

Thanks to @ukri.org NERC for funding the current work, with other support and community from @uk-comet.bsky.social 😎🌋⚒️🧪

As well as testing the models, we spend time discussing their implementation and benchmarking.

We provide a range of model files with the paper, as well as detailed instructions on how to build poroelastic magma mush deformation models using Finite Element modelling software (COMSOL Multiphysics).

We also contrast entirely poroelastic magma mushes, with magma mushes that contain both poroelastic regions AND melt-rich domains.

The composition of the mush can alter both the spatial and temporal ground deformation patterns for an identical magma resupply simulation.

Melt compressibility also impacts the temporal evolution of ground deformation, and how we may experience post-injection uplift or subsidence.

Awkwardly, in terms of interpreting deformation, the effect of compressibility also trades off with mush reservoir geometry...

In this paper, Rami explores different modelling approaches to simulate volcano ground deformation from melt resupply to magma mushes.

Key parameters are tested: porosity, permeability, compressibility, mush geometry, and composition.

Melt compressibility has a big effect on deformation amplitude.

"If you ignore all the fact-free “world-leading this and world leading that” BS..." --> same way I get through every day at work 😂

That's an incredible snap, mate 📸!

The story continues...

Haha, yeh, and it really didn't help the point that I was trying to make, in that "even ChatGPT would draw a mush extending to the base of the crust" 🤣🙈

Some of the plumes at Krasheninnikov certainly looked quite steam rich 🧐

Sarina clearly lives for the drama…!
