Abstract

Most of the well known problems of landslide study are revised and summarized. Various schemes of the basic signs for the landslide classifications (natural, auxiliary and regional) are illustrated and mentioned. Theoretical problems of the landslide terminology, taxonomy and nomenclature, including their mechanisms, process and structural parts, as well as a general scientific definition of the landslide concepts, are discussed. The report reflects the authors view on the object and subject of landslide study.
