Fecha de publicación: | 29-jun-2011 | Editor: | Springer Nature | Citación: | Marine Geophysical Researches 32(1-2): 245-256 (2011) | Resumen: | The Baraza Slide is located in the northwestern Alboran Sea, western Mediterranean region, between 590 and 830 m water depth, and its morphology, seismic facies and sedimentary structure are analyzed based on multibeam bathymetry and very high to medium resolution single-channel seismic records. During the Pleistocene and Late Quaternary this landslide has undergone repeated slope failures characterized by a succession of two main types of mass movement, the first of the mass-flow type and the second of the slide type. This study also reveals that the western sector of this landslide could still be active. The relatively high slope gradients, a sedimentary column characterized by the presence of under consolidated layers and earthquake shaking related to tectonic activity on the margin are the factors governing the genesis and post-mobility behavior of the Baraza mass movement. The recognition and analysis of these factors suggest that the Baraza Slide should be considered as a geo-hazard in the tectonically active Alboran Sea | Descripción: | 12 pages, 7 figures | Versión del editor: | https://doi.org/10.1007/s11001-011-9132-2 | URI: | http://hdl.handle.net/10261/45692 | DOI: | 10.1007/s11001-011-9132-2 | ISSN: | 0025-3235 | E-ISSN: | 1573-0581 |
