Abstract

The first results of the geodetic observations, performed by the local network of GPS created approximately one year ago are summarized. It is revealed, that the Vladikavkaz breaking zone demonstrates complete passiveness in the field of contemporary horizontal motions. Furthermore this recently seismoactive breaking zone is not already for a period several decades active even at the level of the moderate seismic events. Exception is the weak Khataldon earthquake 2008, which occurred in the limits of Vladikavkaz breaking. In connection with this the zone of breaking can be considered as structure, which is located now in the situation of seismic calm, and in the future capable of generating strong earthquake.
