Did you know H.P. Lovecraft's At the Mountains of Madness reads almost like a geology paper? Set in Antarctica, a continent with real fossil forests, ancient rift systems, and a tectonic history stretching back to Gondwana, Lovecraft turned deep time into cosmic horror.

Subduction interfaces are complicated – and that’s their beauty! The dynamics of subduction zones are strongly influenced by the subduction interface. Understanding its rheology enables geodynamic modellers to better simulate these systems and unravel the fundament...

What controls the dynamics of subduction zones? A big part of the answer lies in the rheology of the subduction interface. In today’s post, Dr. P. Io Ioannidi breaks down its importance and explores how we can model it effectively. blogs.egu.eu/divisions/gd...

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 d...
