| | Abstract | | Recently, some research reported that the locations of earthquake are important to estimate the site amplification factors for long-period ground motions observed in the Kanto Basin. For examples, Tsuno et al. (2012) indicated that long-period ground motions in the Tokyo Metropolitan Area and its vicinity were more largely amplified by earthquakes located in Northern Nagano Prefecture and Eastern Shizuoka Prefecture than those located in Tohoku Region, using aftershock data of the 2011 Tohoku Earthquake. In this paper, we investigated site amplifications in the Kanto Basin, based on the Rayleigh waves theory using the subsurface structures proposed by Yamanaka and Yamada (2006). |
