Potential Locations of Strong Earthquakes in Bulgaria and the Neighbouring Regions

Figure 6

Locations of seismogenic nodes (black dots and relevant labels) capable to generate M6+ events. Gray circles mark hazardous (D) nodes identified in this work. The yellow outlined circle no. 170 shows seismogenic node recognized as capable to generate M6+ in Gorshkov et al. [47]. The red lines denote the active faults according to the EDSF database [48]. The light blue dots are epicenters of earthquakes with (see Table 1). The dark blue circles present the instrumental seismicity revised by the International Seismological Centre (http://www.isc.ac.uk/iscbulletin/search/catalogue/) of the region for the periods 1900-2021. Some of the nodes are slightly shifted from the fault position due to the effect of nonverticality of seismogenic faults.
