The double-difference location method was applied to records of 22 local seismic stations with an epicentral distance of less than 25 km in order to retrieve highly accurate locations of hypocenters with an accuracy of less than 20 m. The hypocenters are well-clustered and distinctly map the system of activated faults. The fault system has a complex geometry being composed of several fault segments with different orientations. Some of the segments intersect each other. The orientations of the segments coincide well with the focal mechanisms. We have introduced and evaluated the so-called fault instability of the individual fault segments.
