Seismic Risk Features of a Destructive Earthquake Zone

Abstract

The features of changes in the seismic risk of the zone of a strong earthquake, associated with both destructive consequences and the processes of these recovery. These two factors are the main reason for the change in the seismic vulnerability of preserved (not destroyed) and newly constructed buildings and structures, therefore, changes in the seismic risk of a fairly large area. This problem is not well understood, despite its importance in terms of assessing and reducing risk. The article proposes to divide the zone into subzones on the basis of a specific earthquake, taking into account the intensity and scale of destruction of buildings. This approach makes it possible to more reliably establish the general and local features of the change in the seismic risk of the restored earthquake zone.
