What drives the extensional deformation in the central Apennines (Italy)?

What drives the extensional deformation in the central Apennines (Italy)?

The central Mediterranean is a geodynamically complex region shaped by the interaction of multiple active subduction zones. In Italy, the central Apennines display a distinctive pattern of surface deformation that is proposed to be linked to a slab break-off beneath the area. In this week’s blog post, Maaike, a PhD student at ISTerre in Grenoble, France, explores the key processes driving surface ...[Read More]

How numerical modeling helps decipher the dynamics and evolution of Venus

How numerical modeling helps decipher the dynamics and evolution of Venus

Earth’s sister, Venus, is a planet whose evolution is drastically different from our own. Unravelling the hidden mysteries behind the divergent evolution of these two planets could hold the key to understanding what makes a planet habitable. Using numerical modelling, Diogo Lourenço and Cédric Gillmann unveil the dynamics of Venus while linking them to observations. In today’s blog pos ...[Read More]

A New Look at the Rheology of Deep Subduction Zones

A New Look at the Rheology of Deep Subduction Zones

Subduction zones are dynamic regions where intense geological processes like earthquakes, volcanic eruptions, and the recycling of oceanic crust are constantly at play. A key factor that influences the behavior of these zones is *interface rheology*—the strength and viscosity of the boundary (the interface) between the subducting and overriding plates. Understanding this interface is crucial for i ...[Read More]

Coexisting Forces in Geodynamic Modelling: Pros, Cons, and Synergies of Analogue and Numerical Modelling

Coexisting Forces in Geodynamic Modelling: Pros, Cons, and Synergies of Analogue and Numerical Modelling

Geodynamic modelling helps us understand Earth’s internal processes by providing a framework to test hypotheses. Analogue modelling uses physical models governed by the laws of nature, with resolution down to Planck’s length. In contrast, numerical modelling employs mathematical methods to approximate solutions to the physical laws governing Earth’s processes. Each modelling approach comes with it ...[Read More]
