Abstract:
An earthquake with magnitude ML=5.8 (Мw=5.6) and epicentral intensity I0= 8 MSK64 occurred in the vicinity of the city of Pernik (SW Bulgaria) on 22nd of May 2012. The earthquake was followed by intensive aftershock activity. In the study the fault plane solutions for 20 earthquakes (the main shock and 19 aftershocks) registered by the national seismological network of Bulgaria are presented. The orientations of the fault plane solutions and spatial distribution of the aftershocks coincide with the NW-SE trend of Pernik-Belchin fault. Additionally, basic geodynamic analysis is performed.
