Description:
This paper examines the results of fault microdisplacement analyses obtained from sites located both at the surface and underground in western Slovakia. The results of surface monitoring showed significant annual climatic effects on the various displacement components. In contrast, the results of underground monitoring in caves showed minimal climatic effects. It is seen that the influence of climate decreases markedly with depth. The yearly peak-to-peak amplitude of climatic variations may be as high as 1 mm at the surface but only 0.1 mm underground. The amount of tectonic displacement can be determined once such climatic considerations have been taken into account. Our fault displacement measurements show horizontal strike-slip rates of tenths of mm or hundredths of mm per year. In addition, vertical displacements have been recorded at Prekážka Quarry, Driny Cave, and Slopy Cave. The network is sufficiently dense to identify changes in displacement activity recorded during recent, significant, earthquake events. Furthermore, three gauges have also helped to determine the local stress orientation in Driny Cave., Miloš Briestenský, Blahoslav Košťák, Josef Stemberk, Ľubomír Petro, Jozef Vozár and Lucia Fojtíková., and Obsahuje bibliografii

Description:
In this paper, results from the long-term monitoring of two deep-seated slope deformations are presented. These deformations are considered typical of the types of landslide that occur in the high mountains of the Western Carpathians. The localities are situated in similar geological settings and this has enabled direct comparison of their development over the past 30 years. The monitoring has been undertaken using the extensometric gauges, TM71. At the Parohy Site, results from the scarp area show a significant vertical displacement trend of 0.07 mm per year. At the Štrochy Site, results from the crown area show a horizontal crack opening trend of 0.015 mm per year. Monitoring is ongoing at both sites., Miloš Briestenský, Blahoslav Košťák, Josef Stemberk and Jozef Vozár., and Obsahuje bibliografii
