Understanding the location and nature of Quaternary active crustal faults is critical to reduce both impact fault rupture strong ground motions hazards (when these causing earthquakes). It also important for understanding how where deformation related plate tectonics accommodated along geological structures (oftentimes folds). In Chile, work on in upper crust (neotectonics or earthquake geology...

The Apenninic chain, in central Italy, has been recently struck by the Norcia 2016 seismic sequence. Three mainshocks, 2016, occurred on August 24 (M W 6.0), October 26 5.9) and 30 6.5) along well-known late Quaternary active WSW-dipping normal faults. Coseismic fractures hypocentral seismicity distribution are mostly associated with failure Mt Vettore-Mt Bove (VBF) fault. Nevertheless, followi...

Base-level maps (or “isobase maps”, as originally defined by Filosofov, 1960), express a relationship between valley order and topography. The base-level map can be seen as a “simplified” version of the original topographic surface, from which the “noise” of the low-order stream erosion was removed. This method is able to identify areas with possible tectonic influence even within lithologicall...

New fieldwork and tectonic analysis has been carried out along the Andean morphotectonic frontline between 46°30’ 47°30′S. The right lateral transtensional Marques–Zeballos Pass fault system (MZPRS) controlled 800–1200 m uplift of Andes at 16.1–18.1 Ma. Our data indicate that there was no lower Miocene contractile event frontline. Main Thrust (MAT), which is deeply rooted in upper crust a retro...

lake maharlu basin is located in a synclinal valley of the folded zagros. the frame and rugged structure of the basin is made of three units of mountainous geomorphologic, smooth levels and tectonic hole and evolved during several geological periods under the effect of interactive relations of tectonic, climatology and hydro geomorphologic processes. in this study, the researchers applied histo...

Introduction: We describe the morphotectonic features of the Acheron Fossae (AF) graben system (NW Tharsis). The AF were early recognized as a heavily fratured region [1,2,3,4], and Viking-based geologic mapping summarized the major geologic surface units of the region [5], but no detailed tectonic investigation has been performed yet. An ESEto EW-trending topographic high of Noachian age, stan...
