Cumulative mudtlows

Abstract

A special type of mountain valleys has been recognized within areas of their intersection by active faults a considerable concentration of energy takes place. As a consequence, "cumulative" mudflows are formed which are distinct by higher dynamics arid destructive properties. A few examples of this type of valleys are given, and results of mudflow occurrence are discussed. The author gives reasons for more detail investigations of the cumulative mudflow on special test sites chosen in valleys prone to mudflows.
