Reliable modeling of earthquake strong ground motions requires the understanding of seismic source and wave propagation phenomena. The key issue is the study of combined effects of the source characteristics and structural properties, which are usually investigated separately. Joining the scientific expertise of the Czech and German research groups, this project aims at the development of unified 3D numerical modeling tools for integrated studies of the earthquake source and the propagation of seismic waves through realistic media. This will allow us to investigate 3D combined effects, such as: basin effects on wave propagation from finite-extent earthquake sources, high-frequency source directivity in random media and in highly heterogeneous fault zones, and rupture propagation of and seismic radiation from dynamic source models on non-planar faults utilizing slip-weakening and rate-and-state friction models. The developed methods will be applied also in source and structural tomography and will be provided to the scientific community to facilitate inter-institutional cooperation.
