Abstract
Attenuation of peak ground acceleration (PGA) and peak ground velocity (PGV) of statistical Green's functions with Mw=5.2 calculated by different kinds of Q models and envelope models is compared with previous empirical attenuation relations. The attenuation of the statistical Green's function calculated by the region-specific Q model and envelope model based on scattering theory for subduction-zone earthquakes proposed by Satoh (2004, 2006) agrees with the region-specific empirical attenuation relation for subduction-zone earthquakes. On the other hand, Boore's (1983) envelope model tends to overestimate the empirical PGAs and PGVs as larger hypocentral distances are. Satoh et al's (1994) envelope model underestimates them by nearly 50 % in the hypocentral distances of less than 100 km.
