Present-day stress field and deformation in eastern Austria

摘要: We analysed fault plane solutions and borehole breakouts in the eastern part of Eastern Alps found a heterogeneous stress field which we interpret as transition zone three different provinces: western European province with NW to NNW SH orientation mainly strike-slip faulting regime; Adriatic radial pattern thrust Dinaric-Pannonian NE regime. The Pannonian basin seems be WNW orientation. A regime stimulating prevails Alps. south Bohemian basement spur major tectonic structure high rheological contrast surrounding units has strong influence on exhibits highest seismicity at its tip due concentration. From constructed vertical profile decoupling Northern Calcareous from underlying foreland. Both Molasse Flysch-Helvetic are considered candidates for horizons observations their behaviour. seismological data, suggest horizontal across caused by weakened central Alpine lithosphere.
