Multi-scale Models for Seismic Hazard Analysis
Seismic hazard analysis often requires multi-scale models to capture both regional and local effects at a given site, such as smaller, high-resolution features imbedded in larger-scale structures. Examples include analysis of dam structures, fault damage low-velocity zones and sedimentary basins inside regional models with outer length scales determined by seismic source location or extent of hazard maps. In order to obtain unbiased hazard estimates in the multi-scale models, the smaller-scale features must be merged with the regional models in an optimal fashion. We invite contributions that describe imaging of high-resolution crustal features, methods (including machine learning) for seamless merging of such features with regional models and application/validation of multi-scale models in seismic hazard analysis (e.g., dynamic rupture modeling and wave propagation simulations).
