Three groups of recurrent earthquakes have been identified within the Mukacheve series of 2005–2006. After relocation with application of differential arrivals and station terms their sources arranged into almost a vertical plane along the azimuth of ~120°, approximately coinciding with a plane of normal faulting determined for all the earthquakes as a single source mechanism. The results are consistent with data on some other local source mechanisms as also on an ambient field of extensional stresses in the local crust and a significant horizontal gradient of vertical movements across the epicenter area of the series.
