Summary | We evaluated the relationship between the distribution of seismic intensity and the hazard area concerned with slope failure distribution in the case of the Mid Niigata prefecture earthquake in 2004, the Noto Hanto earthquake in 2007, and the Niitagaken chuetsu - oki earthquake in 2007. The result of our analysis, slope failure appeared in more than seismic intensity scale 5 lower and the tendency of the serious disaster increasing when the seismic intensity is more than 5 upper. It suggests that the slope failure check might be carrying out when the seismic intensity observed more than 5 lower. |
