Recent tectonics and slope failures in the Western Carpathians

We describe several examples of recent tectonics and related slope failures from the Western Carpathians of Slovakia. The monitoring data confirm the idea of non-uniform geodynamic behaviour of individual tectonic units as well as the idea that even an extremely low rate of displacement both in landslides and along active faults may endanger human life and property. The crack-gauge TM-71 is adopted as the monitoring device in our study, and we confirm its reliability for measuring in-plane displacements in severe conditions with a resolution of 0.1 mm/year, simple manipulation, minimum maintenance requirements and reasonable price.
