Abstract

 In Nankodai, a residential area in Sendai City, serious damage was caused by the 1978 off Miyagi Prefecture Earthquake (M_J7.4) and the 2011 off the Pacific coast of Tohoku Earthquake (M_W9.0). To better understand the mechanism of the damage, it is necessary to have a better understanding on the seismic response of the residential area during the 1978 and 2011 events with high accuracy by taking into account site effects. In this study, we evaluated the seismic waveforms at the damaged area based on moderate earthquake observation records with very high density. Furthermore, based on the estimated waveforms, we discussed the characteristics of ground motion which influenced the seismic damage of the residential area. The estimated waveforms and findings will be useful in future study of seismic performance of residential areas.
