Seismic Anisotropy Reveals Deep-Mantle Dynamics - Eos A new study offers insight into the viscous BLOBs at the base of Earth’s mantle.

Happy to share that our recent paper on global-scale geodynamic + seismic anisotropy simulation is on Eos spotlight. With @bstein.bsky.social , Manuele Faccenda , @michapons.bsky.social
Enjoy reading! :)

Today, we kicked off this term's department seminar series with Dr. Michael Pons (@michapons.bsky.social) coming from @gfz.bsky.social. He presented his research on geodynamic modeling of tectonic activity on Earth and Venus 🌍🌌

#DUresearch #Modeling #GFZ

3rd paper from @poulamiroy.bsky.social's Ph.D. just out at doi.org/10.1029/2025.... Combined global models of mantle flow and anisotropy constrain deformation mechanisms and viscosity, density and hence compositional structure of lowermost mantle. With Manuele Faccenda, @michapons.bsky.social & me.

Awards & medals nomination EGU, the European Geosciences Union, is Europe’s premier geosciences union, dedicated to the pursuit of excellence in the Earth, planetary, and space sciences for the benefit of humanity, worldwide.

Deadline on June 15th ❗Take a moment to nominate a colleague or early career scientist for an EGU Geodynamics Division award. It’s quick to do and a great way to recognize their work!

YouTube video by Comisión de Tectónica De-coding plate tectonics through Andean geodynamics

Hey everyone, here’s a video of a talk I gave yesterday for the Geological Association of Argentina about the geodynamics of the Central Andes. Sorry for my French accent, which somehow gets even stronger in situations like this 👏 www.youtube.com/watch?v=zD7U...

Wondering what is the anisotropic signature of slab-induced plumes from thermochemical piles in the lowermost mantle? Then find out from Poulami Roy's paper agupubs.onlinelibrary.wiley.com/doi/10.1029/... co-authored by Manuele Faccenda, @michapons.bsky.social and myself

Six Hundred Leagues Under the Earth This geodynamic model of the Earth at 850 Ma explores the expression and evolution of the Earth's surface as a result of the complex interaction between cold subduction and warm mantle plumes. Model developed using ASPECT geodynamics code and visualised using Paraview.

Hey everyone 😊
My global geodynamic numerical model of the Earth is part of the Helmholtz Imaging Best Scientific Image Contest 2025! I’d really appreciate your support 🤗, feel free to check it out and vote if you like it 🗳️ 😁

Normal Fault Interactions in Seismic Cycles and the Impact of Fault Network Geometry Seismic cycles of faults far apart and across-strike are periodic and become less periodic and out of phase when closer Seismic cycles of faults along-strike are periodic, and become more synchro...

Paper alert! 🚨
We investigate how the geometry of the fault network affects seismic sequences on normal faults, and how this might affect seismic hazard assessment using physics-based models of earthquakes.
agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Scientific recycling: In doi.org/10.1029/2024... I use results from Poulami Roy's Ph.D. thesis to address why plume excess temperatures are much less than temperature drop across the lowermost-mantle thermal boundary layer. Further co-authors @michapons.bsky.social and Matteo Jopke. (continued)

Two days left to vote for @The_GA Journal Awards!

I'm delighted that my tectonics article (using seismic tomography to take fieldtrips to the mantle) is in the final three.

I would appreciate a vote from any GA member who found it helpful.

New paper by @khushgr.bsky.social couples vegetation, 3D climate and biogeochemistry continuously over 250 million years!

We find that changing plant distribution was a major long-term carbon cycle feedback and may account for up to ~5 C of warming at some times
