The term Jisuberi, or landcreep, in Japan, refers to a slow and continuous displacement of a mass of debris formed by a former landslide; there is no basic difference between landcreep and creep proper.Yamakuzure, or landslide signifies a rapid movement of a mass of bedrock or mantle constituting the mountainside. Destructive landcreeps will hardly be distinguished from certain landslide.
Landcreeps and landslides usually take place in sparsely populated mountainous districts, and are rather far from general attention and interest, although it is considered that recent reclamation and overlumbering in those areas have resulted the increase of their occurrences. In mountainous countries, gentle slopes formed by landcreeps and landslides are often preferred as locations of settlements or arable land, because of their lower inclination and more fertility of soil.Repeated occurrences of disasters on the same spots, and the preferability of such spots for habitation are dilemma hard to get out.
