During map in Belica River Basin, it was found two areas with continuously developed landslides that could mark as sliding belt. Genetic analysis established that the development of the sliding belts can not be fully explained on the basis of geological or geomorphologic features. Therefore, it was accessed, in this paper, to seismic analysis as potential genetic factor of this colluvial process. This analysis is required to analyze of recent seismism as well as paleoseismism. Genetic characteristic of the earthquake has been analyzed on the basis of data collected during instrumental period as well as the structural and morphological characteristics of the river basin and its surroundings.
