Formalized Lineament Analysis as a Basis for Seismic Monitoring of Platform Areas

Abstract

The research is devoted to one of the natural hazards of safety of nuclear power plants on the example of the Kursk Nuclear Power Plant (NPP). The analysis of recent geodynamic activity in the area of the Kursk NPP was performed on the basis of digital processing of space images in order to detect active fault zones for optimal organization of seismic monitoring. A formalized lineament analysis was applied (LESSA program) and stable statistical characteristics of the spatial distribution of small and extensive lineaments were obtained and analyzed. The expression of the post-Turonian regional flexure of the sedimentary cover in lineament forms is shown. An estimation of the existence of recent reactivation of Precambrian fracture zones has been made Kursk NPP area and in the adjacent region. The tectonic stability of the territory adjacent to the NPP has been confirmed. Weak seismic events recorded during seismic monitoring were classified as man-made.
