“Buried Alive by the National Coal Board”: Commemorating the 60th anniversary of the Aberfan Mining Disaster

EGU Geolog | 21 October, 2026
Aberfan is located in the South Wales Valleys and developed as a coal mining village during the industrial revolution in the mid-1800s. The village is much like any of the other villages scattered across the region - rows on rows of small terrace houses, nestled into the sides and bottom of steep, glacially eroded valleys. However, this quiet, beautiful village is also known across the world for its connection to one of the UK's worst mining disasters.

Explosive Inside, Effusive Outside: What is it that makes volcanoes erupt the way that they do, and how does that relate to how all ECRs feel inside?

Let's get the joke out of the way first, because I made it to myself more than once while finishing this piece: "explosive inside, effusive outside" is a fairly accurate description of the average Early Career Researcher trying to hold it together inside the current state of academia. Calm, composed, professionally cheerful on the surface; a small pyroclastic flow of funding anxiety, precarious contracts, growing responsibilities for the lowest payslips and looming deadlines going off somewhere just beneath it. It turns out this is also, with slightly more rigour and considerably less existential dread, a pretty good description of a silicic volcanic dome.

No AI comments. None. No exceptions.

Yesterday, an AI posted a comment on this blog -- or tried to. It was superficially helpful, relevant to the top of the post it was on, and turned out to contain that characteristic blend of things we already knew and things that are (subtly or blatantly) wrong. Needless to say, we shoved it in the spam folder.

In Defence of Uncertainty: Why we can’t avoid it and why we need it

EGU Geolog | 16 October, 2026
Welcome to the second post in our GeoLog series on communicating uncertainty! Written by students from an interdisciplinary course at the University of Tübingen led by Dr. Solmaz Mohadjer, this series highlights how reframing the unknown as a strength can transform science communication. In this piece, Ana Isidora Ciobanu and Sarah Lind show why uncertainty is far from a scientific flaw, but is, in fact, the very engine of scientific progress. By drawing parallels to how we manage everyday unknowns, like checking weather forecasts or route traffic, they unpack concepts like epistemic versus aleatory uncertainty, falsifiability, and the Information-Gap Theory. Using a vivid metaphor of science as a growing tree, they demonstrate why embracing what we don't know fuels curiosity and prevents knowledge from hardening into dogma, concluding with a practical three-step guide to help readers navigate uncertainty-related stress.

An Interview on the importance of simplification – modeling the weathering crust and microbial activity on ice sheets

The weathering crust of ice sheets or glaciers is a layer of porous ice, bordering on impermeable ice below and influencing the meltwater storage and production. This physically complex environment harbors a wide range of microorganisms that themselves affect the weathering crust and contribute to darkening of ice surfaces. The two factors - microbial community and ice structure - and their respective impacts on the melting of ice sheets and glaciers are difficult to separate in field experiments which is why modeling of this environment is beneficial. A model is a simplified representation of a real-world system or process in mathematical terms, that allows scientists to test different scenarios.
