A Korean Ground Motion Simulation Model Comprising of Stochastic Point-sourse and Shaping Window Models

Abstract

The aim this study is to develop a ground motion simulation model for the Korean peninsula to simulate ground motions propagated from scenario-based earthquakes. The proposed numerical model can be used to construct ground motion prediction equations and to perform probabilistic seismic hazard analyses. The model consists of stochastic point-source and shaping window model. The model parameters of these models are calibrated based on ground motions recorded at various bedrock site stations during 10 earthquakes with ??˃3.5 occurred in the Korean peninsula from 2015 to 2019. To confirm accuracy of ground motion simulation model, 5% damped pseudo spectral acceleration with T = 0.1s-10s of recorded and simulated ground motions are compared.
