The Geodynamics (GD) Division of the European Geosciences Union (EGU) coordinates the scientific programme and related activities on all aspects of geodynamic processes in the lithosphere, mantle, and core of the Earth and the terrestrial planets. The division also promotes scientific interchange and dissemination of activities carried out by its members.

This blog serves as a platform for the geodynamics community to share news, articles and events. In our Wednesday blog posts, we have several regular features, such as the Geodynamics 101 series, which serves to show the diversity of topics and methods in the geodynamics community in an understandable manner for every geodynamicist and science-fan. We also have Wit & Wisdom posts full of wit (but rarely wisdom). Interesting regional and global geodynamics are discussed in the Remarkable Regions and Peculiar Planets series. The latest geodynamics news can be found in our News & Views posts. On Friday, we have a weekly column called Ask the Sassy Scientist, where an anonymous scientist (who is sassy) answers questions from our readers. If you would like to contribute to the blog as a guest writer, don’t hesitate to contact us!

The Geodynamics Division hopes to address a wide range of topics, as well as the major challenges related to geodynamics. The division publishes updates on Facebook and Twitter
