Description The seismicity of the northern part of the Eastern Alps, the Western Carpathians and the southern part of the Bohemian Massif is investigated by means of the new seismic stations and a review of earthquake catalogues. The final data set of earthquakes covers the time span from 1267 to 2004 and comprises 1968 events in total. An attempt at a seismotectonic interpretation of earthquakes based on the geological overview of the region is presented. Gravity and aiborne magnetometry data in addition to seismic events are collected and cross-border maps are compiled and analysed in order to determine the spatial extent of these geological structures. Correlation between the epicentres of earthquakes and lineaments derived from gravity data is discussed for major historical earthquakes. This data set enables us to determine seismically active fault structures and to get an insight into the fault system interaction. The ability to assess the potentially seismically active fault structures enables improved hazard assessments in future.
