This thesis focuses on the verification of the Čirá-Kopanina fault existence using morphostructural analysis and geophysical surveying. The verification of the fault zone was based on the analyses of the digital relief model, river network parameters and selected relief features that indicate tectonic activity with a high probability. Based on these analyses, the fault was identified and subsequently verified using geophysical methods. The searched tectonic line passes through the village of Čirá in the Jindřichovice upland district (Krušné hory Mts), continues east of the village of Kopanina and heads south into the Cheb Basin along the Libocký Brook. The direction of the Čirá-Kopanina fault was determined as approximately north-south (348ř - 168ř) and thus corresponds to the north-south orientation of the hypocentres of the West Bohemian earthquake swarms. The Čirá-Kopanina fault zone could thus be a potential source area for the earthquake swarms at the boundary of the Cheb Basin and the Krušné hory Mts. crystalline complex. However, its activity needs to be verified by a further research.
