Abstract
The objective of the present paper is to investigate the distribution of the seismic frequency and the cause of the incidence of the disaster zone in Kobe district by Hyogoken-Nambu earthquake with Kobe Jibankun-the geological information database. The geological data of the secondary wave velocity and the others for the seismic frequency analysis are the pasts of the data that are collected in Kobe Jibankun. As the result of the analysis, the seismic frequencies that were observed correspond mostly to them that were analyzed by the method of the seismic frequency analysis, and by drawing the comparison between the distribution of the seismic frequency that was analyzed by it and the distribution of the wooden house damage in Kobe district, and the correlative seismic parameter relative to the wooden house damage was revealed, and it was clear that its ratio was rising suddenly while the parameter became more than the certain value.
