Abstract The large slow‐moving landslide of Maca is located in the upper Colca valley (southern Peru), a region characterized by well pronounced rainy period, and intense recurrent sustained seismicity. landslide, developed deep lacustrine deposits, has recently accelerated, threatening village. This work aims at understanding rupture mechanism causes recent reactivation/acceleration. We present multidisciplinary characterization that includes: (i) geological morphological mapping field;...
The migration of Homo erectus in Southeast Asia during Early Pleistocene is cardinal to our comprehension the evolution genus Homo. However, limited consideration rapidly changing physical environment, together with controversial datings hominin bearing sites, make it challenging secure robust timeline needed unveil behavior early humans. Here, we reappraise first appearance datum Javanese H. by adding most reliable age constraints based on cosmogenic nuclides [Formula: see text]Be and...
Abstract Our understanding of the style and rate Quaternary tectonic deformation in forearc Central Andes is hampered by a lack field observations constraints on neotectonic structures. Here we present detailed analysis Purgatorio fault, recently recognized active fault located southern Peru. Based remote sensing (Pléiades DEM), define as subvertical structure trending NW‐SE to W‐E along its 60 km length, connecting, eastern end, crustal Incapuquio Fault System. The accommodates...
We have estimated recent river incision rates using the in situ-produced 36Cl cosmogenic nuclide concentrations. The target site consists of a ~25 m high vertical profile along polished cliff located Jurassic limestones Vésubie catchment area, southern French Alps. exposure ages sampled surface range from 3 to 14 ka, i.e., after Last Glacial Maximum. Our data suggest as first approximation linear age/height relationship and lead mean rate 2.2 mm a−1 over last ka. More precisely, are...
Abstract This study provides a comprehensive characterization of various hydrothermal systems in Southern Peru ranging from the faulted Precordillera's steep topography up to volcanic High Cordillera (>4,000 m asl). The objective is investigate thermal anomalies that may potentially serve as new geothermal resources. Our integrated approach combines: (a) geochemistry 14 hot springs sampled throughout Tacna region, and (b) 3D numerical modeling coupled groundwater heat transfer considering...
A system of active normal faults around the city Cusco have severely damaged in major earthquakes pre-hispanic times, 1650 and 1950 CE. Detailed studies these adjacent to are therefore needed build an understanding seismic hazard region. We present new geomorphological paleoseismological evidence for multiple Holocene on Tambomachay Fault, a 20 km-long fault that runs along northern margin Basin. The western segment preserves scarps cut moraine crests with mean throw 4.3 ± 0.4 m. determine...
Abstract The first erosional front of the south‐eastern Alps has been affected by several deep‐seated landslides. movements a Jurassic limestone sequence underlain an upper Trias unit (Keuper) mainly composed marl and clays. Horst‐ graben‐like structures, newly formed gravitational faults, outflow other field evidence suggest that such are consistent with lateral rock spreading processes. An example processes is ‘La Marbrière’ slope, where investigations have revealed three distinct zones...
Abstract The western flank of the Central Andes offers a unique geomorphological record large paleolandslides that are well preserved on long time‐scales (i.e. ≥Pleistocene) due to long‐lasting aridity this region. However, lack chronological constraints those landslides limits our understanding respective role tectonics and climate their triggering. Here, we report new 10 Be surface exposure dating obtained one giant slope‐failures: Limaxina landslide (northern Chile, 19°S). Five tightly...
Deciphering the impact of short-term or long-term forcing on fluvial incision, as well understanding influence local (channel lithology and morphology) global (tectonic motions) parameters in spatial variation incision efficiency, are ongoing geomorphological research fields. To shed new light these issues, we chose to study “Hautes Gorges du Verdon” (High Verdon HVG), located foreland Southwestern Alps. We collected 24 samples along three polished surfaces for Cosmic Ray Exposure (CRE) 36...
