Plate interface lubrication is essential for stabilization and continuation of subduction process for million of years. The magnitude of plate interface lubrication determines transfer of stress between two converging plates, topography of mountain belts, transportation of volatiles to the mantle, and return flow of high to ultra-high pressure rocks to the earth’s surface. In this week’s blog, I ...[Read More]

Geodynamics: It’s in the air we breathe!

Fabio Capitanio and edited by Gokul V.S. July 20, 2022

Have you ever wondered how Earth became habitable. In this week’s news and views, we have Fabio Capitanio, Associate Professor at Monash University sharing insights into the role Geodynamics in the evolution of Earth and life on it. Our planet has unique features which make it suitable for life. Understanding how the Earth became habitable is necessary to answer the most fundamental question ...[Read More]

Into the anisotropic Earth

Rajani Shrestha July 6, 2022

While we have sent several rovers to Mars, drilling down even just to the mantle of our own planet is a challenge that we are yet to overcome. How is it then that we know all these things about our planet’s interior? It turns out, we do not need to be inside the Earth to know what is happening there. Observations from geophysics and geochemistry can inform us about the processes and the properties ...[Read More]

Happy blog birthday!

Can you guess how old the blog turns today?
Hint: Look at the subduction 😍

The EGU Geodynamics blog is 5 years old today! *throws confetti* Imagine being on the same contract in the same country for that long… Wow. Truly incredible. So let’s have a look at what we did over this past year of blogging. What did we do? Write and edit, mainly. I know – who’d’ve thought that is what editors do, right? But yes, writing and editing was done in abun ...[Read More]
