“…These lines of evidence lead it to be suggested here that the dis− placements in the Hornsund area could reflect contemporaneous tectonic pro− cesses associated with spreading along the Mid−Atlantic Ridge. Stemberk et al (2010) and Briestenský et al (2014) have described similar recorded pulses.…”

This paper presents the results of direct 3−D fault displacement monitoring along the northern shore of Hornsund Fjord, SW Spitsbergen, Svalbard. The fault displacements have been recorded using three permanently installed optical−mechanical crack gauges since 2009. The monitoring data from all three sites provided evidence for a remarkable slip event that lasted from September 2011 to May 2012. The cause is discussed in some detail with consideration given to both exogenic (temperature changes, surface processes) and endogenic processes (isostatic rebound and regional seismicity). It is proposed that tran− sient fault slips recorded had a tectonic origin and were caused by approximately W−E ori− ented compression corresponding to regional compression in the Svalbard area.

“…These events should all be seen as the result of tectonic deformation initiated by the pressure pulse. Supplementary data indicate an affinity between the deformation process and large global disturbance within the Earth's crust (Stemberk et al, 2010). …”

“…This was followed by specific movements or unusual local earthquakes. It has been shown that this activity could also be recognised on some of the major continental tectonic structures of Europe such as those in the Rhinegraben in Germany, the Central Apennines in Italy, and the Gulf of Corinth in Greece (Stemberk et al, 2010).…”

“…The present paper analyses a range of data (tiltmeter, rangefinder, hydrological, seismic) that have the potential to record natural tectonic effects for the period relevant to the pressure pulse described in Stemberk et al (2010). It was considered to be particularly advantageous to exploit data derived from a geophysical tiltmeter station located in a gallery deep within the crystalline rocks that form the mountains.…”

This paper reports on a study of active tectonics undertaken in the intracratonic setting of central Europe in the junction zone between Eastern Alps and Western Carpathians. The study site is focused on the karstic system of Driny Cave in the Malé Karpaty Mts, Slovakia. A range of geological, geomorphological, and in situ displacement data are presented. From previous geological mapping and our slickenside analyses, it is clear that the cave system has developed along significant fault structures. Further geomorphological investigations pointed towards ongoing faulting and block movements. For example, a number of slope failures can be seen on the hillsides above the cave and numerous fresh speleothem breaks can be observed within the cave. To test this hypothesis, three optical-mechanical crack gauges were installed in 2005. These gauges confirmed and quantified the ongoing movements. The NNE-SSW striking fault has recorded a strike-slip trend of 0.1 mm/year and a normal fault trend of 0.03 mm/year. The NW-SE striking fault has recorded a strike-slip trend of 0.04 mm/year. In addition, it has been possible to define their precise kinematics. Moreover, different strike-slip mechanisms along two transverse fault systems point to a horizontal stress field orientation. These results confirm the existence of active tectonic structures within central Europe. It is considered that the methodology described here can also be applied in other intracratonic settings where karstic cave systems are present. This would help define potentially seismogenic areas where unambiguous evidence for active faulting is lacking.
