Abstract
In this study, velocity response spectrum near period 1s was evaluated from ground motion indices for local government sites because that ground motion records were not stored in the main shock of the 2007 Noto Hanto Earthquake. Analyzing relationship among PGA, JMA seismic intensity and average velocity response spectrum, the average velocity response spectrum can be precisely estimated by using these ground motion indices. Next, correlation between average velocity response spectrum and damage ratio of wooden house was examined based on the records of the 2007 Noto Hanto Earthquake. We clarified that the average velocity response spectrum of period 0.7 to 1.2s (Sv0.7-1.2) has the highest correlation to the damage ratio of wooden house. Finally, a good correlation between Sv0.7-1.2 at local government sites estimated by the proposed method, and damage ratio of wooden house was shown.
