Bringing rocks down to the café with new postdoc Dr Anna Theurel. It is fun to be discussing sintering dynamics and the textures that point to sintering petrogenesis.

Yup. Can confirm it tastes like magma. Hazy magma at that. #Aldi

Regular video chats with my closest collaborator, Jeremie Vasseur, has become a fun daily check-in. I really enjoy our ongoing work together.

This paper is now accepted! It's been a long road with multiple journals along the way.

Magma mush permeability is sensitive to the crystal framework surface area. Our model could (and should) be used to compute melt extraction timescales in the run-up to large crystal-poor volcanic eruptions. With @jameshickey77.bsky.social hopefully this will help with mush deformation models too.

It's great to catch up with Patrick Sullivan who has developed new numerical approaches to bubble nucleation in complex liquids - including magmas - that bring some order to the myriad observations of nucleation of bubbles on crystals. Exciting work with real impact across disciplines.

Roast and ground coffee particles are internally porous. Here's a segmented 2D-slice through a pack of relatively coarse particles, processed by David Zhang at Lancaster University. Next, we'll be running simulations to estimate the coffee bed permeability as a function of grind setting and packing.

There is a universal way to capture the permeability of porous media. Here we demonstrate that by showing how data from a wide range of media with very different pore microstructures all collapse to a single description. An earlier version of this is published here: doi.org/10.1016/j.ac...

If we take known encounters between aircraft and volcanic ash and chart their exposure duration against how much ash there was, we can see that Rory Clarkson (Rolls Royce) is probably right: engines can withstand a bit of ash for short duration flights or 'hops'. It's the total dose that counts.

We live on a volcanic planet. Volcanic eruptions happen every year. The volume of air travel is ever-increasing globally. So many of those flight routes and corridors are close to active volcanoes. So how do we build long-term resilience for the airline industry accounting for volcanic activity?

Recollections of a workshop we held at The National Glass Centre where Earth Science students could meet students of the sculptural arts and try their hands at manipulating hot glass. Importantly, we brought along obsidian and basaltic lava to melt and stretch and mingle in the making. Fascinating.

Work in progress. This is from Dr Tom Lark's PhD. Tom modelled the hot gas flow through 'nozzle guide vanes' within aircraft jet engines. This was to track how and where volcanic ash particles can impact these components, and to assess whether or not they will stick and build up in the engine.

I’m reading 3 volumes of my great grandfather’s WW1 diary, including scraps of typed troop movement orders and hand drawn maps. I’m up to 1917-18, when he was moved from trenches to Palestine.

At Krafla, we also took bespoke equipment with us that meant we could soften and melt obsidian in the field and watch bubbles form and grow as the very low amount of remnant dissolved water exsolves. We wrote about some of these experimental tests from our fieldtrip here --> doi.org/10.30909/vol...

While at Krafla volcano with glass and ceramics artists and Ed Llewellin, we took a few found-blocks of flow banded rhyolite, all covered in lichen, and we cut and polished them in the field. The polished surfaces reveal the spherulitic flow bands, beautifully. This block is about 40 cm.

Krafla, in Iceland, is such a wonderful place. One of the places where obsidian-forming eruptions abound, and where geothermal energy is produced. Perhaps most exciting: a place where we have drilled into rhyolitic magma in the shallow crust and sampled it directly at storage conditions.

Work in review: here's a result from @annabellef.bsky.social's PhD, where she measured the sintering rate of obsidian with some supersaturated dissolved water. She modelled the diffusive water loss during sintering, to arrive at an overall sintering curve that describes the data very well.

In 2021, we were really excited that our paper about the pressure required to operate the French Press coffee maker made the cover of the American Journal of Physics. Glad to find my copy of the issue. Here: doi.org/10.1119/10.0...

Obsidian has become a long-term obsession. It's a material about which I am fascinated. Scientifically, I think it holds unexplored information about silicic eruptions. Poetically, I think it is as dense and weighty as when you hold it in your hands, with important dark resonances.

How does pressure influence viscous sintering behaviour? The higher the pressure, the faster the sintering. Our mathematical sintering framework appears to handle this effect relatively well. We'll be applying this to the sealing-up of tuffisites under the squeezing weight of volcanic domes.

New study from @fabianwadsworth.bsky.social and team examines how crystal-rich magmas deform: a combination of viscous flow and fracture on different spatial scales. Especially relevant to lava dome emplacement. Bravo!

Here's a paper I keep coming back to and which I think is important. Rich with detail, this paper from Paul Cole and collaborators describes ash venting processes at Soufrière Hills volcano (Montserrat). How is this occurring? I think there's a lot more to learn here. 👏🌋👏 doi.org/10.1144/M39.4

How do volcanic particles sinter together with time to form coherent magma again? How is this process affected by the presence of rigid crystals that 'get in the way' of the viscous sintering of magma-particles? Here is some preliminary analysis of existing data trying to reach a unified view.

A sneak-peak at a paper in review... The compressive strength of sandstones seems to transition from a granular (grain crushing) law at high porosities to a porous (pore-crushing) law at low porosities. And this transition can be thought of as a topological inversion of the micro-structure.

In this new paper, we use hydro-granular theory to model magma ascent. In this framework, all magmas are strictly Newtonian locally, but apparently non-Newtonian bulk behaviour emerges from the microphysics; with important implications for shear fracturing at conduit margins. doi.org/10.1038/s432...
