Abstract

This paper investigates an empirical zoning map of seismic intensity and the zoning map of PS-P time from strong motion records observed by an array system in Sendai City. The empirical zoning map of seismic intensity shows a distinctive distribution reflecting local site conditions. In order to investigate such a distribution of intensity in connection to PS-P times at each site of Small-Titan, we analyzed the observed records of Small-Titan by receiver function and complex envelope. It is finally concluded that the distinctive distribution of seismic intensity in the Sendai City area has a correlation with the depth of the bedrock as well as the surface soil conditions.
