A multidisciplinary work integrating structural, geodetic and seismological data was performed in the Catanzaro Trough (central Calabria, Italy) to define seismotectonic setting of this area. The is a structural depression transversal Calabrian Arc, lying in-between two longitudinal grabens: Crati Basin north Mesima south. investigated area experienced some strongest historical earthquakes Ital...

Abstract The Calamocha fault is an 18-km-long, NNW–SSE striking pure normal that moves down the northern sector of Jiloca graben with respect to Neogene infill Calatayud basin (central Iberian Chain). Its structure and kinematics are characterized by means detailed geological mapping, morphotectonic analysis data recording at outcrop scale. represents inversion a previous contractional zone und...

Hydrocarbon seepage phenomena can be found in most petroleum provinces located both coastal and ocean regions. The present work aims to identify, map quantify oil seep candidates the maritime portion of Espírito Santo Sedimentary Basin using Synthetic Aperture Radar imagery from Radarsat-2 Sentinel-1. selection SAR images was made based on their basin coverage area. Meteorological oceanographic...

The Atacama Desert, on the western margin of Central Andes, hosts some world's largest porphyry copper deposits (PCDs). Despite a hyperarid climate, many these PCDs have undergone secondary “supergene” enrichment, whereby has been concentrated via groundwater-driven leaching and reprecipitation, yielding supergene profiles containing valuable records weathering landscape evolution. We combine h...

rivers are unstable environments affected by natural or human factors in changing their directions and patterns. in this study, the tectonic effects on the pattern of the gharasou river in the north of kermanshah city have been studied. aerial photos (years 1955 & 1990), satellite images (etm, year 2000) and topographic as well as geologic maps were used as research tools. the procedure of the ...

The Algerian margin is located at the slow-rate convergent boundary between African and Eurasian plates experienced several strong earthquakes in last centuries. Among them, 2003 Mw 6.8 Boumerdès event has triggered large turbidity currents slightly concave canyons of slope numerous cable breaks abyssal plain. In this study, we explore where, how when tectonic inversion off left witnesses seafl...

Mashhad city, the second most populous metropolis of Iran, with a population of more than three million, lies between two seismically active regions of Binalood and Kopet-Dagh. In recent years, the city has grown around the South Mashhad (SM) fault zone in the south. Given the vital role of the SM fault in influencing the seismic risk of the city, this study is aimed at the evaluation of the fa...

Morphotectonic investigations were carried out by the use of morphometric indices which serve as a tool of identification in regions with active tectonic warp. Landforms in active deformation area are produced from relations of tectonic and surficial processes. One of the most significant landforms underground is rivers that are extremely responsive to tectonic movements mainly uplift and tilti...
