Tectonic processes which led to the generation of the Alps, Carpathians, Dinarides, and the Pannonian basin are still on work. In particular they affect the transition zone from the European platform over the Eastern Alps to the Pannonian basin. GPS network solutions confirm the ongoing lateral extrusion of East Alpine crustal blocks directed to the Pannonian basin. Earthquakes and neo-tectonic...

The Cingoli arcuate anticline is part of the Apennines fold-thrust belt in Italy. The anticline nvolves sedimentary carbonate strata generally affected by syn-thrusting contractional tructures such as bed-normal pressure solution seams, folds, and reverse faults. An xception is constituted by an outcrop in the anticline hinge, where sub-horizontal arbonate and chert beds are affected by joints ...

The New Madrid seismic zone (NMSZ) in the central United States is one of the most active regions of intraplate seismicity in North America and site of the devastating 1811–1812 earthquake sequence (Nuttli, 1973; Johnston and Schweig, 1996). The NMSZ lies within the NE–SW trending Reelfoot rift (Fig. 1), which represents a failed rift arm that developed during the Late Proterozoic and Early Cam...

The damaged rock around mature faults forms a zone of low seismic wave 24 velocities, which can perturb important earthquake rupture properties. In particular, waves 25 reflected within the fault zone structure can induce short-duration slip pulses, an apparently 26 predominant earthquake rupture mode. Another known mechanism to generate slip pulses is 27 strong velocity-weakening friction. Her...

[1] We investigate the development of fracture distributions as a function of displacement to determine whether damage around small and large faults is governed by the same process. Based on our own field work combined with data from the literature, we find that (1) isolated single faults with small displacements have macrofracture densities that decay as r, where r is distance from the fault p...

Magnetotelluric (MT) studies can map subsurface resistivity structure and have located zones of low resistivity (high conductivity) within major strike-slip fault zones worldwide which have been interpreted as regions of elevated fluid content. This study describes MT data from the eastern part of the North Anatolian and the East Anatolian Fault Systems (NAFS and EAFS) and presents the results ...
