- Abstract
The conditions necessary for the origin of block landslides are: (1) geological and lithological slope structure corresponding to a two-layered medium with a brittle upper layer and a plastic lower layer; sufficient thickness of the upper layer in order to transfer loads to the lower one, which generate irreversible deformations in the latter, and to form blocks; (2) conditions for plastic deformations and lateral spreading of masses of the lower layer. These conditions serve as criteria for the forecasting of the locations of block landslides. The geological structure of some parts of Bulgaria is favourable for their origin. The determined low speeds of contemporary movements of the block landslides provide the possibility to use the affected territories for construction and other economic activity.
