Seismic hazard maps for Serbia, for return periods of 95, 475 and 975 years (PGA) were created at the Seismological Survey of Serbia in 2018, based on all available data on historical and current seismicity and the latest knowledge on neotectonic, geological and seismic properties for the territory of Serbia, in accordance with the requirements of Eurocode 8: Design of structures for earthquake resistance (EN 1998-1).
For the purposes of seismic hazard calculation, the territory of Serbia is divided into zones, with the adopted assumption that seismic hazard within the zone is constant, and is shown by maximum ground acceleration for the entire zone (one color on the map).The values of maximum ground acceleration, which are shown on hazard maps, refer to the soil of type A (rock or rock-like geological formation, including at most 5 m of weaker material on the surface (Vs,30 > 800 m/s)).
The values of macroseismic intensity on the Seismic hazard maps for the return periods of 95, 475 and 975 years were calculated by multiplying the calculated PGA values and soil factor for the corresponding calculation point. For soil factors, the recommended values by Eurocode 8 have been adopted. Soil types are categorized according to the terrain slope, calculated on the basis of a DTM (resolution 30 m).
