It is very important to know the distribution of slope failures quickly just after the big earthquake against the additional sediment related disaster. Generally, the sabo facilities damage check after the earthquake is carried out when the seismic intensity scale is exceeded 4 by JMA were observed. We evaluated the relationship between the distributions of seismic intensity and the hazard area concerned with slope failures distribution in the case as followed as ; The Mid Niigata prefecture earthquake in 2004, The Noto Hanto earthquake and the Niigataken chuetsu earthquake in 2007. Following our study indicated that slope failures 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 suggested that the slope failure check might be carrying out quickly when the seismic intensity observed more than 5 upper.
