The largest total vertical movement of 0.35 mm (2008-2018) occurred at Kostanjeviska Jama (Southwestern Pannonian Basin-Dinarides). Two abrupt displacements observed at that cave location correspond to pre- and post-seismic episodes in 2014 and 2015. At Poloska Jama (Southern Alps), more gradual and continuous displacement on a monitored bedding plane of 0.13 mm down-slip (2008-2018) was observed. This movement is attributed to slope relaxation as well as tectonic activity on the Julian Alps thrust fault and the seismogenic Ravne Fault, which generated earthquakes at M-w = 5.6 in 1998 and M-w = 5.2 in 2004. At Jama pri Svetih Treh Kraljih in Dinarides, activity on the Ravne Fault was shown as sinistral-horizontal (0.1 mm) and vertical (0.15 mm) movement along an E-W-oriented tectonic structure. This shallowly buried site also experienced cyclic seasonal displacements. At Zupanova Jama, multiple short-term horizontal dextral and sinistral strike-slip pulses (2016-2018) demonstrated active tectonic micro-deformations within the wider zone of the Dobrepolje and Zelimlje faults. At Postojnska Jama, two episodes of vertical movement on a NW-SE-oriented fault are associated with earthquake swarms: the first episode was in 2010 (M-LV = 3.7) and the second in 2014 (M-LV = 4.3). In-cave flood events do not coincide with periods of micro-displacement activity in the studied caves, and therefore are not the drivers of the micro-displacement.
