For analysis of earthquake motion, the Gaussian mixture model was applied to the 99-dimensional feature vector representing the temporal characteristics of a strong motion on the basis of its Husid plot. In this study, the period-dependent feature vector based on the evolutionary power spectrum was defined. Furthermore, the Gaussian mixture model was applied to the period-dependent feature vector. The proposed method was applied to the earthquake motions observed from the Tokaido-oki earthquake that occurred at 23:57 September 5, 2004. The period-dependent feature vector and the Gaussian mixture model by proposed method were included of the characteristics of earthquake motion.  For the dispersibility of surface wave found in the feature vector, the element model from the Gaussian mixture model was compared with the dispersion curve calculated from the soil profile.</p>"},{"@language":"ja","@value":"<p>地震動特性の評価・分析を目的に，筆者らが提案した地震動の特徴抽出・次元縮約手法を用いて，地震動の時間・周波数分析への適用を行った．正規化加速度累積パワー曲線(Husid
