ABSTRACT
The authors studied two rock avalanches that were triggered on the northwest slope of Moiseev Mountain, Novaya Zemlya, by seismic shaking after a strong underground nuclear explosion. Through investigation of motion characteristics and distribution of the rock avalanches, analysis of granular structure and mineralogical composition of rock deposits we have established that the runout length of the avalanches is influenced by the granular structure of the constituent rock debris.
