Summary It is very important to express the scale precisely intelligibly about sediment disaster to offer to inhabitants when disaster occurred. In addition, Explanation method, which is easy to understand a disaster scale, and to express, is important when I compare a disaster of many parts of the world integrally and arrange it. The authors developed the method of express using indexation of a scale of sediment disasters, and we argue about directionality of the index that can express the actual situation of sediment disaster adequately.
