Abstract

We presented an empirical predictive model for the long-period (1-15sec.) ground motion and examined the validity of the model by comparing with the observations. We computed the acceleration response spectrum of 5 and 1 percent damping using the strong ground motion records retrieved by the K-NET, KiK-net, and JMA Seismic Intensity Observation Network. We defined the shakeability at a site by the spectral ratio of the response spectrum observed at a site to the ones at seismic baserock (average VS ~ 2.4 km/s) predicted using the empirical attenuation model proposed by Yuzawa and Kudo (2011). Shakeability maps for long-period (1-15 sec) ground motion in Japan were provided and they were examined using typical observed records.
