The main aim is to create an interactive map of seismic hazard of the territory of the Czech Republic with help of the up-to date scientific knowledge and the system of its upgrading. The map will be consistent with the recommendation of the International Atomic Energy Agency for eveluation of seismic hazard at the sites of nuclear facilities. It will serve as the background material during the process of approving seismic safety of the nuclear buildings, facilities and infrastructure. The system of continual upgrading will enable to include the new results of science in the fields of seismic hazard and experience from new earthquakes.
