Reviewing of stochastic description of the spatial variation of ground motion and coherence function model
This study addresses the topic of the spatial variation of seismic ground motions as evaluated from data recorded at dense instrument arrays. It concentrates on the stochastic description of the spatial variation, and focuses on spatial coherency. The estimation of coherency from recorded data and i...

description | This study addresses the topic of the spatial variation of seismic ground motions as evaluated from data recorded at dense instrument arrays. It concentrates on the stochastic description of the spatial variation, and focuses on spatial coherency. The estimation of coherency from recorded data and its interpretation are presented. Some empirical and semi-empirical coherency models are described, and their validity and limitations in terms of physical causes discussed. Finally, by comparing and analyzing the simulation results of different coherence function models on the spatial correlation of ground motion, some suggestions on the selection of coherence function model are put forward. |
