Our aim is to improve the understanding of geodynamic processes operating inside the solid Earth and their surface manifestation at a broad range of spatial and temporal scales through advanced numerical modeling. Our research focii are located at both plate boundaries and within the plate interiors, inside the deep mantle and at the surface. We constrain our models by multidisciplinary surface observations acquired by the GFZ and the international scientific community and look for practical applications of fundamental research, like tsunami early warning and hazard assessment. To approach our aims, we develop our own numerical methods and tools, but also extensively employ and co-develop numerical techniques provided by the international community.
Dynamics of Early Earth and Evolution of Plate Tectonics
Plate tectonics is the most important geological process on Earth, shaping its surface, and making it unique among the planets in the Solar System. Yet, how plate tectonics emerged on Earth, which tectonic regime was before and which factors controlled evolution of plate tectonics in the Earth history remain controversial. We address these questions in the framework of the ERC Synergy Grant Project MEET (Monitoring of Earth Evolution through Time) using numerical modeling to test various geodynamic hypotheses with new geochemical data.

Global Geodynamic Modeling
The Earth's mantle behaves like a very viscous liquid over extended geological periods. Cold earth plates sink from the surface to the core-mantle boundary, and hot material rises from there in the form of mantle plumes and as large-scale upwellings. By numerical modeling with different observation data, in particular from seismology, geodesy and mineral physics as boundary conditions, we try to better understand processes in the Earth's interior. In particular, we investigate the following topics:

Tsunami Hazard Assessment and Early Warning
Since the Great Sumatra 2004 Boxing Day earthquake and tsunami GFZ provides research and methodologic development in the fields of tsunami hazard assessment and early warning. Section 2.5 Geodynamic Modeling supports these activities with numerical modeling of tsunami generation, propagation and coastal impact within both deterministic and probabilistic frameworks. Our Section also participates in the development of the innovative GNSS-based technology for tsunami early warning.
