There are three elements in the mechanism of seismic ground motion. It is a thing about a source region, propagation path and ground condition. To separate influence of propagation path and ground condition, I acquire the attenuation of seismic wave according to distance in a frequency domain, and compare Kanto region with Hokkaido region. Based on the characteristics of the attenuation in a high frequency domain, I investigate the effect of sedimentary structures around Tokyo.
