Earthquake factors and precipitation factors are two major factors considered in natural hazards in case of Niigata-ken Chuetsu Earthquake In addition to that, the situations will be prolonged recovery and rehabilitation due to unexpected strong ground motion or continuing aftershocks, inevitable reconstruction of community based function may be delayed for snow period The regions of near epicenter are mentioned to have sympathetic series of aftershocks to various stimuli including active faults The authors regard natural hazard analysis as provision of essential information to structural safety or disaster mitigation In this manuscript, we referred to probabilistic risk assessment of occurrence earthquake during snow period with comparison of Poisson process and Bernoulli sequence in determining optimized preparedness This paper consists as to, 1) Geo-morphological and meteorological features of near epicenter, 2) Pigeonhole past major earthquake, 3) Summary of snowfalls and snow depth with using sequence of Japan Meteorology Agency's data, finally the authors indicate concepts as probability of occurrence earthquake in snowy season in order to alleviate social damage the point of view from geotechnical subjects
