抄録 本研究は, 地震動のコーダ部にレイリー波が多く含まれているという前提のもとに, 1
観測点で抽出された地震動の水平成分と鉛直成分のスペクトル比 (H/V スペクトル比) …

抄録 An analytical method is presented for computing horizontal-to-vertical spectral ratios
(H/V) of Rayleigh and surface waves propagating on a layered half-space, in which the …

抄録 We examine the differences of empirical site characteristics among S-wave, P-wave,
coda, and microtremors and interpret them theoretically. Data used in this study are …

抄録 We compare site-specific response characteristics inferred from microtremors with
those from seismic shear waves in terms of (1) predominant frequencies (PP),(2) horizontal …

抄録 The peak ground acceleration at K-NET in Ojiya during the Mid Niigata Prefecture
Earthquake in 2004 is significantly larger than that at JMA in Ojiya, while the trend reverses …

抄録 We conducted aftershock observations in Chuo Ward, Fukuoka city to make clear
reasons why building damage had been concentrated near Kego Fault during the 2005 …

抄録 Long-period microtremors were observed at 63 ooints in Kobe urban area after the
1995 Hyogo-ken Nanbu Earthquake. The purpose of the observation was to clarify the depth …

抄録 A dense strong-motion array in the central part of Odawara city, Japan has been
installed for understanding the detailed spatial distribution of ground motion characteristics …

抄録 In this paper, wave propagation in an irregular ground due to incident surface waves is
formulated by combining the 2.5 dimensional thin layered element method and the 2.5 …

抄録 Biwako-seigan fault zone is one of the most active faults in Japan, located around
western shore of Lake Biwa. According to The Headquarters for Earthquake Research …
