Studies related to the Geodynamics Division include all aspects of geodynamic processes in the lithosphere, mantle, and core. They encompass different approaches, including observations, imaging, theory, modelling (numerical simulations and laboratory experiments), and interpretation. Examples include the dynamics of subduction, mid-ocean-ridge processes, vertical and horizontal plate movements driving mountain building and basin formation, lithosphere dynamics, mantle convection, and core dynamics.

Under pressure: measuring stress within the crust
At the geodynamic scale, tectonic forces guide the distribution of stress. Stress in the Earth is not constant, but varies through space. Variations in gravitational energy caused by changes in mass distribution within the Earth, forces acting at plate boundaries, and basal mantle drag all cause stress to vary and act in different directions. Overall, stress plays a key role in tectonics. It allows plates to deform, faults to slip, and earthquakes to occur. It can trigger or delay future …

What’s blobbing inside the Earth? – insights from numerical modelling
Seismic waves tell us that something unusual is happening in the lowermost few hundred kilometers of Earth’s mantle. Beneath Africa and the Pacific lie two enormous thermochemical structures known as Large Low-Shear-Velocity Provinces (LLSVPs). These “large blobs” are slower to transmit shear waves, but beyond that, their physical nature remains one of the biggest open questions in deep Earth geodynamics. In this week’s blog, Poulami Roy, postdoc at Durham University (UK), takes us through how these LLSVPs can be numerically …

FrenSZ workshop: a French interdisciplinary initiative around subduction zones.
Since 2022, the annual FrenSZ workshop has been bringing together a vibrant and interdisciplinary community around subduction zones in France. In this week’s blog post, we dive into how FrenSZ is organized, highlight its scientific outcomes and how it is opening new connections on the international stage. A large French community. In France, a fairly large community of Earth Scientists devote their research efforts to subduction zones through very diverse approaches, rooted in fieldwork investigations, laboratory experiments, geophysical and seismological …

Running Models, Chasing Bugs – from Crashes to Convection
An illustration by Prachi Kar Mantle convection may unfold the hidden stories of planetary interiors over billions of years, but geodynamic models can crash in milliseconds. While figures in papers often show smooth convective flows with elegant plumes and slabs, the path to those results is not very easy. This week, Prachi Kar, a PhD candidate at Arizona State University, shares her honest thoughts on the part of geodynamics no one advertises: the art and emotional labor of debugging. “Okay. …

Current issue of the EGU newsletter
In our February issue, we are following pioneering scientists into extreme places in the name of discovery, from a day-in-the-life of an Antarctic researcher working on the sea ice to how the Viking spaceships took space plasma from theory to observation. Marie Cavitte shares her experience of the Blue Book traineeship in science for policy and Elsa Abs talks about their work with soil microbes. EGU's President thanks our 12,000 volunteers from 2025 and we share the 24 training schools and member-organised meetings we have funded in 2026. Deadlines approach for the EGU26 photo competition and Early-bird registration fees, and there is a job vacancy in the EGU Executive office in Munich, Germany!
All this and much more, in this month's Loupe!
