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.
