ABSTRACT

It has been determined by the author that more than 1500 national economy facilities are located in dangerous areas, which are subject to active and dangerous landslides, mudslides, floods, gully erosion, earthquakes and other geological processes.

Determination of the reasons lying behind these processes and establishment of regularities in their development is a necessary requirement for engineering – geological assessment of territories in question and follow – up designing of engineering protection schemes.

The present work presents a new methodical approach to zoning of regions of Tajikistan according based on the conditions of development of all kinds of processes and their applicative associations. Under this approach the leading role is attributed to seismisity.
