Analog Models of Fold-and-Thrust Wedges in Progressive Arcs: A Comparison With the Gibraltar Arc External Wedge [PDF]

Frontiers in Earth Science, 2020
The timing and kinematics of the different types of structures and the associated vertical-axis rotations that permit an arcuate external wedge to acquire progressively its curved shape throughout its deformation history—known as progressive arcs—are key

Imaging the Low Dip Onset of the Gibraltar Arc Subduction in the Gulf of Cádiz Using OBS Receiver Functions

Geophysical Research Letters
Using P and S‐wave receiver function analysis we investigate the lithospheric structure in the Gulf of Cádiz through a combination of ocean‐bottom seismometers and onshore seismic stations located in southwest Iberia and northwest Africa.

3D Modelling of Archaeoseismic Damage in the Roman Site of Baelo Claudia (Gibraltar Arc, South Spain)

Applied Sciences, 2022
This study deals with the morphometric characterization and quantification of earthquake damage in the ancient Roman city of Baelo Claudia in South Spain (Gibraltar Arc) by means of the use of 3D modelling from drone imagery.

Population Genetics of an Endemic Species <i>Mongoloniscus sinensis</i> (Isopoda: Oniscidea) and Diversification Dynamics Across Northern China. [PDF]

Ecol Evol
We explored the population genetics and demographic history of an isopod species endemic in temperate China on the basis of three mitochondrial genes. Three clusters were identified. The Midland group has the highest genetic diversity, and the greatest differentiation between the East and West groups was due to the geographical barrier caused by the ...

Spatial Patterns of Global Peste Des Petits Ruminants Virus and Its Potential Risk Assessment for Various Wildlife Habitats. [PDF]

Ecol Evol
This study found that according to the analysis of PPR epidemic data from 2007 to 2024, the driving mechanism of key climatic and environmental factors such as temperature seasonality (standard deviation × 100) (Bio4), annual mean temperature (Bio1), isothermality (Bio3), mean diurnal range (Bio2), mean monthly precipitation in March (Prec3), and the ...

Crustal rheology and seismicity in the Gibraltar Arc (western Mediterranean) [PDF]

Tectonics, 2008
On the basis of the lithospheric structure of the Gibraltar Arc (western Mediterranean), we constrain depth distribution of crustal seismicity and active tectonics by means of rheological modeling. Crustal yield strength and depth of the brittle‐ductile transition zone (BDT) mimic the curvature of the arc with maximum depths of 12–9 km whereas in the ...

Neogene polyphase deformation related to the Alboran Basin evolution: new insights for the Beni Bousera massif (Internal Rif, Morocco)

BSGF - Earth Sciences Bulletin, 2020
Located in the Internal domain of the Rif belt, the Beni Bousera massif is characterized by a stack of peridotites and crustal metamorphic units. The massif is intruded by granitic dykes and affected by several normal ductile shear zones.

Submarine Active Faults and Morpho-Tectonics Around the Iberian Margins: Seismic and Tsunamis Hazards

Frontiers in Earth Science, 2021
The aim of this work is to make a synthesis at regional scale focused on the geophysical characterization of submarine faults around the Iberian margin to identify active structures and analyze their development in the framework of the present plate ...

Geodynamic Modeling of Edge-Delamination Driven by Subduction-Transform Edge Propagator Faults: The Westernmost Mediterranean Margin (Central Betic Orogen) Case Study

Frontiers in Earth Science, 2020
Lithospheric tearing at slab edges is common in scenarios where retreating slabs face continental margins. Such tearing is often accommodated via subvertical STEP (Subduction-Transform Edge Propagator) faults that cut across the entire lithosphere and ...

Crustal and upper mantle velocity structure of Southern Iberia, the sea of Alboran, and the Gibraltar arc determined by local earthquake tomography

Annals of Geophysics, 1997
A "local earthquake tomography" of a large area encompassing the South of Iberia, the sea of Alboran, the Gibraltar arc, and Northern Morrocco, has been performed using first arrival times recorded at various Spanish and Morroccan seismic networks.
