Rifts provide a unique window into the geodynamic system of our planet and the processes that shape the surface of the Earth. The CRYSTALS project aims at a thorough understanding of continental rift dynamics and rifted margin formation by means of a comprehensive multi-scale numerical modelling design.
We welcome Esther Heckenbach who gained one of the competitive Geo.X PhD grants earlier this year. She will focus on "The seismic cycle of great earthquakes: Numerical multi-scale modelling of transients and tipping points." in a strong collaboration with Matthias Rosenau and Onno Oncken (Section 4.1) as well as Ralf Kornhuber (FU Berlin).
