Due to challenges involved in mapping the seafloor at high-resolution (e.g., <2 m), data are lacking understand processes that control evolution of submarine normal fault scarps, which cover large parts global seafloor. Here, we use from autonomous deep-sea vehicles quantify local erosion and deposition associated with a pronounced tectonic surface scarp formed by slip on Roseau (Lesser Antille...

The Sencelles Fault constitutes the main extensional structure of Mallorca Island (Spain), holds a NE-SE orientation, and has been identified as possible seismic source 1851 CE Palma earthquake (VII EMS.) SE termination fault (Sta. Eugenia Segment) features linear bedrock scarp maximum 3.15 m height. last 840 this rocky display significant horizontal banding, with up to five differentially weat...

Dating of submarine volcanic systems is key to understand the history tectonic and interactions within Lesser Antilles arc. In this study, we investigate radioisotopic dating located between Les Saintes (Guadeloupe) Dominica islands in an intra-arc graben bounded west by active Roseau fault. Submarine lava flows domes have been sampled with remotely operated vehicle (ROV) Victor6000 controlled ...

The stability of the slope under excavation in various engineering is a hot issue, and both disturbances other internal factors have contributed to instability slope. study focused on deformation characteristics mechanism exit Qingshuigou tunnel Jiasha Town, Gejiu City, Honghe Prefecture, Yunnan, China. Field survey monitoring are performed reveal slope, which associated with hydrogeologic cond...
