Compilation of the seismic hazard maps in Bosnia and Herzegovina

摘要

Bosnia and Herzegovina is located in the center of the Western Balkans. Until 2018 Bosnia and Herzegovina used the hazard maps based on the macroseismic intensity. The first generation of probabilistic seismic hazard maps of Bosnia and Herzegovina is compiled and presented. Two seismotectonic models were created, the areal and linear (fault) together with the earthquake catalogue filtered out from foreshock and aftershock events. Hazard maps were constructed in terms of the peak ground acceleration, and presented in two maps, with an exceedance on average once in 95 or 475 years. The hazard map used for the design of earthquake-resistant buildings (return period of 475 years with a probability of exceedance of 10% in 50 years) is created for the ground type A with the velocity of the seismic wave propagations of v(s,30) = 800 m/s. These maps have been accepted as a part of the National Annex in BAS EN 1998-1:2018.
