Data concerning faults and their parameters is important information for basic geological research as well as for landscape planning, building activities and assessment of health and natural hazards of geological environment. Ambition of the project is to localize the trace and to identify some spatial, structural, physical, dynamic and age parameters of selected dislocations using combination of multidisciplinary field research methods. Selected faults will be mapped by geophysical field survey methods in combination with bio-detection, detected by radon (Rn) emanations measurements and by means of remote sensing (RS) and digital terrain model (DTM) images, investigated structurally and some of them will be dated. The recent activity of selected fault(s) will be monitored by measurements of seismic events, by analysis of both their focal mechanisms and historical earthquakes and by periodical geodetic measurements based on GNSS technology. First time, for the detection of recent vertical movement along specific fault (the Vikartovce fault in the Tatra region), the very accurate measurements of gravity values will be applied in the Western Carpathians. Fault structures will also be evaluated in relation to some large crustal discontinuities, whose surficial expressions are brittle faults, and which are reflected in anisothropies of lithospheric geophysical fields (recorded in seismic, gravimetric, geo-electric, magnetic and magnetoteluric sections and maps). Expected results of the project will be the structural schemes of accurate traces of studied discontinuites with their specified parameters (inclination, fault damage zone width and character, permeability for fluids, saturation by water, Rn emanations, kinematics, relation to slopes instabilities, recent activity). Potential impact of fault structures on population health will be investigated by radioactivity measurements at residences situated in touch with detected traces of faults with recorded Rn values.
