Both empirical observations and simulations indicate that earthquake faults interact with each other and hence earthquakes cannot be treated as individual independent events. However, this is still largely ignored in standard seismic hazard calculations. The proposed work will aim at understanding the earthquake interactions within fault networks in order to improve seismic hazard estimations. For the test region Lower Rhine Embayment (LRE), Germany, we will perform a comprehensive analysis of seismic hazard assessment based on an adapted physics-based model laboratory “Virtual LRE”. For that, we want to adapt quasi-dynamic earthquake models developed for California to the geometrical configuration in LRE based on a recent fault model for this region. Our goal is to characterize the spatio-temporal variability of seismicity and the complexity of rupture histories and incorporate them into practical calculations of hazard maps.

经验观测和模拟都表明，地震断层相互作用，因此地震不能被视为单独的独立事件。然而，在标准的地震危险性计算中，这一点在很大程度上仍然被忽略。拟议的工作将旨在了解断层网络内的地震相互作用，以改善地震危险性估计。对于测试区域下莱茵河Embayment（LRE），德国，我们将进行地震危险性评估的综合分析的基础上改编的基于物理的模型实验室“虚拟LRE”。为此，我们要适应准动态地震模型开发的加州在LRE的几何配置的基础上，最近的故障模型，该地区。我们的目标是表征地震活动性的时空变异性和破裂历史的复杂性，并将它们纳入危险图的实际计算中。
