The Neogene to Quaternary lateral extrusion of the Eastern Alps towards the Pannonian Basin is accommodated by a system of strike-slip faults. Despite decades-lasting GPS observations, no information on contemporary kinematic behaviour of these faults has been available. Therefore, we had monitored subsidiary and/or conjugated faults associated to these major fault systems in six caves throughout the Eastern Alps over a 1.5–2.5-year observation period by means of high-resolution three-dimensional Moiré extensometers TM71. We confirmed that the monitored faults revealed present-day aseismic displacements at a micrometer level during several activity phases that usually also coincided with periods of increased local seismicity. The annual displacement rates of the monitored faults were mostly about an order of magnitude smaller than the rates of the entire crustal wedges revealed from GNSS. The …
