Original Abstract

Several geodynamic GPS networks have been established within the Moravia territory in last three decades for the purpose of recent crustal movements monitoring. These networks were established by various institutions that are using them for their own particular local investigations. During the same period there have been established five networks of permanent stations, operated again by various public and private subjects. New measurements on selected points of the MORAVA, EAST SUDETEN and HIGHLANDS epoch geodynamic networks affirm previous assumptions about recent activity along the Diendorf -Čebín tectonic zone (DCTZ). Complex evaluation of satellite data together with geophysical and geological knowledge confirm that also the northern part of the Boskovice Furrow is active, with seismic manifestations and noticeable morphotectonic signs perceptible in SRTM and InSar data. The main active risk area is delimited by recently active Konice-Nectava fault system. To this system are tied the post-alpine grabens – Blansko, Moravská Třebová – Lanškroun. The part of the Boskovice Furrow that is connected to the graben structures north of Boskovice represents the most risky area accompanied by recent earthquakes of magnitudes up to M3 with depths to 18 km. Southern limitation of the area constitutes the morphotectonically distinctive zone of the Železné hory – Tišnov tectonic system. Reliable evaluation of neotectonic and recent deformation tendencies at areas of civil engineering interest could serve to better assessment of the associated geodynamic risk. Interconnection of the epoch networks and their integrated evaluation brings better homogeneity of results and their interpretation. To completion of the kinematic model of the Moravia territory contribute also the measurement results on another GPS/GNSS networks.
