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 ...

In this week’s blog, @poulamiroy.bsky.social explores the nature of Large Low-Shear-Velocity Provinces & how modelling with ASPECT geodynamics code helps reveal their role in mantle flow.

Running Models, Chasing Bugs – from Crashes to Convection 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 flo...

In this week’s blog, Prachi Kar shares the unfiltered reality of geodynamic modelling; crashes, segmentation faults and the emotional labor of debugging.

“Running a model makes you a user. Debugging makes you a geodynamicist.”

Growing geological Christmas trees: salt ‘Christmas-tree’ structures explained As geoscientists, we tend to see geology everywhere. Around Christmas, many people stare at decorated fir trees and twinkling lights; salt tectonicists stare at seismic lines and outcrops and see… tre...

It’s beginning to look like Christmas… tree structures! This week Manel and Francina lead us to explore how vertically stacked salt bodies and minibasins grow into tree like architectures, and what these salty “Christmas trees” reveal about basin dynamics and salt flow.
