Abstract

Some results from the geodetic and seismological monitoring of a part of North-Eastern Bulgaria are presented. To evaluate the deformations in the region of Mirovo salt deposit we apply the precise method of permanent survey of displacements using GPS technology. The results of this monitoring show the velocity of displacement for the last 3 years of 6 permanent GPS stations confirming that the seismicity in Provadia region can be considered as “inductive seismicity” related to the intensive exploitation of Mirovo salt deposit. Generally, recent crustal motions in North-Eastern Bulgaria obtained by GPS data analysis reveal identical and no significant residual horizontal velocities relative to Eurasia. Only one point (st.Provadia) located in the central part of the region of interest shows a realtevely higher velocity (especially the vertical velocity) for the last years.
