The trench was excavated within the Mariánské Lázně fault zone, which borders the mountain front of the Krušné hory Mts towards the Cheb basin and intersects the seismoactive zone of Nový Kostel. The present geodynamic activity in the area of Cheb basin is manifested by earthquake swarms and ubiquitous emanations of mantle-derived carbon-dioxide. The trench survey has identified a subvertical fault plane whose recent activity is being investigated by structural and sedimentological analyses, and geochronological methods. Because the very narrow zone of faulting expression within the Quaternary deposits (few tens of cm) does not enable its direct identification by geophysical methods, we used ground truth information from the trench to study possible geophysical attrib...
