This work presents the results of 3-D movements of faults occurring in the Dědičná štola gallery in the Rychlebské hory Mts. during the period between 2014 and 2017. The faults were monitored by TM-71 extensometers. The detected fault slip is nonlinear and is affected by short transient periods of acceleration. One dominant and a series of minor transient fault slip accelerations were recognised. The recorded accelerations were induced by switching two compressional stress/strain states – WNW-ESE to NW-SE compression corresponding to the stress field of the Western European stress domain and to NNE-SSW corresponding to the stress field of the NW part of the Carpathian stress domain. The extensional state, oriented NW-SE, corresponding to gravitational spreading due to the Rychlebské hory Mts. uplift, was recognised.
