Fabric and shear strain of a potential halite detachment below the Swiss Eastern Tabular Jura Open
The Swiss deep geological repository for radioactive waste is to be sited in the easternmost part of the Jura fold-and-thrust belt that forms the external allochthonous units in the Western Alps. Although it is commonly accepted that the J…

Paleoseismology of the Seyring-Aderklaa Fault System, Vienna, Austria  Open
The Aderklaa- and Seyring faults are part of a series of normal faults accommodating active extension west of a releasing bend of the Vienna Basin strike-slip system. The faults are located in the urban area of Vienna and adjacent Lower Au…

The Dinaric Ophiolite Belt: Microstructural observations from the metamorphic sole and its tectonic importance Open
The Dinaric Ophiolite Belt, an integral part of Inner Dinarides located in the Western Balkans, represents a significant piece of the Tethyan Mesozoic oceanic crust recording processes of subduction related metamorphism followed by exhumat…

Characterisation of structural and water flow processes in the upper vadose karst zone using a multi-method approach in a cave Open
The complexity of karst aquifers hampers the assessment of groundwater recharge processes in the upper vadose zone. Consequently processes governing water flow in the soil and epikarst into the vadose zone remain poorly understood. This st…

Assessing the hazard of fault triggering by deep geothermal energy production in an active fault system via a 1D stress model and 3D fault mapping Open
Borehole image data and a 1D-stress model built on open hole logs, leak-off tests (LOT) and image logs are used to evaluate the potential of seismicity caused by fault triggering during geothermal heat production in the city of Vienna. Dat…

3D-seismic evidence for thick-skinned tectonics in a ‘classic’ thin-skinned tectonics region (external Alpine foreland, Switzerland) Open
The northwestern Alpine foreland in Switzerland and France comprises the Late Miocene Jura Mountains, considered a type example for thin-skinned thrusting where deformation of the sedimentary cover is decoupled from the basement along a re…

Three-dimensional numerical modelling of drilling-induced tensile wall fractures Open
Drilling-induced tensile fractures (DITFs) form due to stress concentrations around a wellbore and are in vertical wells typically parallel to the largest horizontal far-field stress and normal to the least horizontal far-field stress. The…

3D‐seismic evidence for thick‐skinned tectonics in a ‘classic’ thin skinned tectonics region (external Alpine foreland, Switzerland) Open
The north‐western Alpine foreland in Switzerland and France comprises the Late Miocene Jura Mountains, considered a type example for thin‐skinned thrusting where deformation of the sedimentary cover is decoupled from the basement along a r…
View article: The temporal evolution of seismicity and variability of b-values along the Vienna Basin Transfer Fault System
The temporal evolution of seismicity and variability of b-values along the Vienna Basin Transfer Fault System Open
The Vienna Basin Transfer Fault System (VBTFS) is the most active fault system in the region between the Eastern Alps, the western Carpathians and the Pannonian Basin. The spatial and temporal distribution of earthquakes along the fault sy…

Interaction of frictional and plastic deformation mechanisms in a clay-carbonate strike-slip fault (Northern Calcareous Alps, Austria) Open
This study presents microstructural investigations of limestone fault rocks formed in a shallow crustal (∼4 km), compressional segment of the Salzachtal-Ennstal-Mariazell-Puchberg fault in the Northern Calcareous Alps. The investigated fau…

Present day tectonic regime in the frontal part of the Eastern Alps inferred trough an integrated approach Open
<p>GPS velocities indicate active convergence between Adria and the European plate, leading to back-trusting in the Southern Alps, uplift in the Tauern Window and to complex strike-slip tectonics associated to the lateral escape of t…

Analysing landforms, borehole logs, and geophysics, for localization and assessment of active faults in the central Vienna Basin (Austria) Open
<p>The formation of pull apart basins and normal faulting at splays along the Vienna Basin strike-slip fault system resulted in the dissection of the Pleistocene river terraces of the Danube. Displacements of terrace segments are vis…

The 1906 Dobrá Voda Earthquake (M=5.7) at the Vienna Basin Transfer Fault: evaluation of the ESI2007 intensity and analysis of the aftershock sequence Open
Aftershock identification plays an important role in the assessment and characterization of large earthquakes. Especially, the length of the aftershock sequence is an important aspect of declustering earthquake catalogues and therefore imp…

Implications from palaeoseismological investigations at the Markgrafneusiedl Fault (Vienna Basin, Austria) for seismic hazard assessment Open
Intraplate regions characterized by low rates of seismicity are challenging for seismic hazard assessment, mainly for two reasons. Firstly, evaluation of historic earthquake catalogues may not reveal all active faults that contribute to re…

Implications from palaeoseismological investigations at theMarkgrafneusiedl Fault (Vienna Basin, Austria) for seismic hazardassessment Open
Including faults into seismic hazard assessment depends strongly on their level of seismic activity. Intraplate regions are characterized by low seismicity, so that the evaluation of existing earthquake catalogues does not necessarily reve…
