In 2017 we went to the Diamond Light Source to test if we could make obsidian by slowly cooling bubbly magma inducing resorption of the bubbles. We found that we could, so long as the cooling was very slow.

Final Registration for the VMSG Annual Meeting 2026 is fast approaching. Abstract deadline has been extended until Friday 8 Dec. We aim to inform registrants of their presentation type (talk/poster) & time slot by 12 Dec.
We look forward to welcoming you all to Southampton!

Met Office news release: 27 November 2025 - New Met Office service to cut aviation disruption from volcanic ash

Today, we're launching our advanced volcanic ash forecasting service to reduce aviation disruption. In 2010, EyjafjallajΓΆkull closed much of Europe's airspace; our new service could halve such disruption and keep skies open during future eruptions.

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.

New paper! The last of EloΓ―se Bretagne's PhD papers is out! Here we generalize our models for permeability to magma mush at any melt fraction. Take a look if you want to model percolative flow of melt through a magma mush and if you want to account for crystal shape.
