Abstract

Summary

An earthquake of moment magnitude 5.6 hit Sofia seismic zone, on May 22nd, 2012. The earthquake occurred in the central part of western Bulgaria at about 25 km south - west of the city of Sofia (the capital of Bulgaria). It is worth mentioning that the May 2012 Mw5.6 earthquake occurred in the area characterized by a long quiescence (of about 95 years) for moderate events. The results favor the idea that neotectonics of the central-western Bulgaria is similar to that of northern Greece with predominant N-S extension.
