Abstract: Information is given about the micro-displacement monitoring network in the Dobra Voda epicentral area, where regular monitoring started in May 2004 and an earthquake occurred on 13 March 2006. The measurement is carried out with the use of verified, stable and sensitive 3D crack gauges TM71 produced by GESTRA Sedlonov, Czech Republic. All the gauges installed across significant tectonic structures in this earthquake zone registered displacements pertinent to the said last earthquake. The results obtained within the Dobra Voda (W Slovakia) monitoring network are analysed in view of the 13 March 2006 earthquake. The measurements indicated remaining sinistral strike-slip displacements in the Dobra Voda fault zone, as well as active subsidence of the Pannonian Basin. Moreover, the measurements indicated even more detailed data about the fault movement development during the instability process developing before and after the earthquake.
