Present-day Seismicity of the Southeastern Elbe Fault System (NE Bohemian Massif)

Original language description

The Variscan Bohemian Massif is disrupted by the NW-SE striking Elbe Fault System in its northern part. The increased tectonic activity associated with this structure is manifested by increased seismicity in the eastern part of the Sudetes. With the useof a temporary local seismic network, the total number of micro-earthquakes located in this region increased to 153 for the period 1996-2003. The local magnitudes vary between -0.6 and 1.8 and the seismic energy was often released in swarm-like sequences. Five seismic events with well-defined P-onset polarities at five or six stations enabled the estimation of focal mechanisms. The present-day activity of the WNW-ESE to NNW-SSE fault systems is discussed on the basis of source mechanisms, the alignmentof the epicentres, as well as morphological and geological evidence. The majority of the recent seismic activity is concentrated in a 40-60 km wide zone of a generally NW-SE trend. This structure represents a regional zone of weakness wit
