タイトル（英）：	EVALUATION OF LONG-PERIOD EARTHQUAKE MOTIONS BASED ON DEEP UNDERGROUND STRUCTURE IN THE KANTO PLAIN -A STUDY USING K-NET DATA SET FOR THE IZU ISLANDS EARTHQUAKES, JULY.2000-
抄録（英）：	Strong motion records during the 2000 the Izu Islands earthquakes with long-period components were affected by the deep underground structure in the Kanto plain. This paper evaluated the characteristics of long-period earthquake motions based on the distribution of 3D basin sturucture in the Kanto plain using the pseudo velocity response spectra and the index of amplitude amplification. As results, it was found that the relation between the earthquake motions with 6-9 seconds in period and the depth to the seismic bedrock correspond very well. Therefore it will become inevitable in the future to prepare reasonable long-period motions for the seismic design of structures with long natural period such as tall buildings and base isolated structures.
