Geodynamické riziká severnej časti Malých Karpát

Abstract

Abstact In the scope of my Ph.D. thesis, the epicentral Dobrá Voda erea was selected for study of geodynamical hazards connected with active faults crossing the area. There was chosen some geomorphological, geological as well as geotechnical methods to discover recent tectonic regime. The obtained results showed close relationship between fault striking and drainage system orientation as well as erosion furrows orientation. Furthermore, wide-ranging slope deformations are located ďong faults with proved activity and the both phenomenons were studied and registered. Moreover, striking faults are reflexing by tufas, sag ponds and swallow holes occurence on the surfaoe. The subsurface active fault display is documented by' sinter damages along the fault in the local Zbojrucka and Slopl Caves. This manifestation influenced these caves to studS' fault microdiplacements and the net was extented by two extensometric TMTI gauges situated on the surface localities too. The monitoring results showed significant tenths and hundredths of mm movement trends per year as well as strain regime ohanges dwing local singnificant earthquakes. On the other hand, sence of the fault displacements showed sinistral block rotation in the wide-rangilg sinistral Mur-Mtirz-Leitha fault zone, which can be changed into dextral block...
