For this reason, it is necessary to make for the avalanche hazard map expressed the dangerous zone. It must be contained that the order of hazard, starting zone, track, runout zone, magnitude of avalanche, etc. First of all, it is very important to point out the dangerous slope probability of avalanche occurrence. Next step, it will be determined the order or prevention method by the avalanche magnitude and kinds of disaster for the avalanche. This report deals with the method to select the dangerous slopes for the avalanche through a statistical analysis of past avalanche activity (inclination, kind of plants, starting areas, frequency occurrence, etc.) Furthermore, the physical and mechanical properties of deposited snow were measured at the starting zone soon after avalanche have occurred. It indicated relationship among kind of plant, coef. of friction and adhesion.}, pages = {107--114}, title = {雪崩の危険度について(その1)}, volume = {4}, year = {1982} }
