First results of movement of 25 m long vertical pendulum in Magdalena Cave are acquired. They show particular declinations from vertical axis regarding stress changes in Earth's crust. 2D data of pendulum movement are transferred in real-time to Prague. The results are comparable with other pendulums in Czech Republic. Parallel to pendulum studies the automatic 3D monitoring of tectonic micro-movements in Velika Gora in Postojna cave system is organized but not in real-time yet. In Slovenia there are 6 extensometer TM 71 installations in karst caves that are situated close to possibly active fault zones. Monitoring is generally organized once a month.
