History
The authors found that many huge primary landslides occurred in pre-historic ages in the Niigata district, Japan. The volume of huge primary landslides is of the order of 10^8m^3 which have many secondary and tertiary landslides in them. The volume of landslides is of the order of 10^7~10^5m^3 for the secondary, and 10^5~10^3m^3 for the tertiary ones. Metamorphically speaking, the primary, secondary and tertiary landslides can be called mother, daughter and granddaughter landslides, respectively. Most of the present landslides correspond to the secondary and tertiary landslides. They have occurred due to a reactivation of the slip surfaces and cracks originated by previous landslides, especially in the marginal areas of the primary ones. The Mushigame landslide which occurred in 1980 is a typical example of it. Therefore, an analysis of the occurrences and movements of the primary landslides is essential to an understanding of present landslide activities and to prevent the disasters associated with them.
