Stochastic gound motion simulation for crustal earthquakes in Japan Itoi, Tatsuya


In this study, an empirical simulation model of stochastic ground motion for crustal earthquakes in Japan is proposed based on the ground motion records observed by K-NET in Japan from 1997 to 2011. The proposed model is developed based on that by Rezaeian & Der Kiureghian (2010). The characteristics of ground motion depends on various parameters such as magnitude, distance from source to site and local site conditions (shallow soil as well as deep subsurface structure), which is included in the parameters in the proposed model. The proposed model is considered useful when conducting probabilistic risk analysis of structures such as base-isolated or vibration-controlled buildings.
