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.

可靠地模拟地震强地面运动需要了解震源和波传播现象。关键问题是研究源特性和结构特性的组合效应，这通常是分开研究的。该项目结合捷克和德国研究小组的科学专长，旨在开发统一的三维数值建模工具，用于综合研究震源和地震波通过真实介质的传播。这将使我们能够调查3D的综合效果，如：盆地的影响波传播从有限范围的地震源，高频源的方向性在随机介质中，在高度异质性的断层带，破裂传播和地震辐射的动态源模型上的非平面断层利用滑动弱化和速率和状态摩擦模型。所开发的方法也将应用于放射源和结构层析成像，并将提供给科学界，以促进机构间合作。
