Subsurface Imaging in Urban Areas With Ambient Noise Using DAS and Seismometer Data Sets: Granada, Spain

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 11, November 2024.
Abstract Distributed acoustic sensing (DAS) is an innovative technology with great potential for acquiring seismic data sets in urban areas. In this work, we check the suitability of a DAS data set acquired in Granada (Spain) for retrieving subsurface reflectivity from ambient noise. The fiber‐optic is a pre‐existing underground telecommunication cable

New 3D Velocity Model (mTAB3D) for Absolute Hypocenter Location in Southern Iberia and the Westernmost Mediterranean

Earth and Space Science, Volume 11, Issue 10, October 2024.
Abstract The Trans‐Alboran Shear Zone is one of the most seismically active areas in the westernmost Mediterranean, where a wide variety of tectonic domains have developed within the context of oblique convergence between Eurasia and Africa plates. In this region, earthquakes occur close to seismogenic structures, some of them large enough to cause ...

Fallas de bajo ángulo vs. estructuras transcurrentes en la Zona Interna Bética: el caso de la falla de Mecina y el sistema de fallas del sur de Sierra Nevada

Estudios Geologicos
La falla de Mecina se sitúa al SO de Sierra Nevada y allí afecta al contacto entre los complejos Nevado-Filábride y Alpujárride. Posteriormente su significado se extendió a todo este contacto, definiéndose entonces el detachment de Mecina, un despegue ...

Active Shortening Simultaneous to Normal Faulting Based on GNSS, Geophysical, and Geological Data: The Seismogenic Ventas de Zafarraya Fault (Betic Cordillera, Southern Spain)

Tectonics, Volume 43, Issue 2, February 2024.
Abstract The central Betic Cordillera, southern Spain, is affected by an uplift related to the NNW–SSE Eurasia‐Nubia convergence and shallow ENE–WSW orthogonal extension accommodated by the extensional system of the Granada Basin. The combination of geophysical, geodetic, and geological data reveals that the southwestern boundary of this extensional ...

Tectonic control on the palaeogeographic evolution of thrust‐top basins at the active margin of the Guadalquivir Basin (central Betic Cordillera, S Spain)

Basin Research, Volume 36, Issue 1, January–February 2024.
Summary chart of the stratigraphic framework of the study sub‐basins in the wedge‐top depozone of the Guadalquivir Basin compare with olistostromic deposits emplaced in the foredeep depozone. The stratigraphic division of the Upper Miocene deposits in the foredeep (at the right part of the figure) is based on different authors: MO.19: Martínez del Olmo
