Hydrothermal vents jetting out water at 380 degrees +/- 30 C have been discovered on the axis of East Pacific Rise. The hottest waters issue from mineralized chimneys and are blackened by sulfide precipitates. These hydrothermal springs sites actively forming massive mineral deposits. Cooler clear to milky support exotic benthic communities giant tube worms, clams, crabs similar those found Galápagos spreading center. Four prototype geophysical experiments were successfully conducted in near...
The Gulf of Cadiz, located at the southwestern Iberian margin, is characterized by widespread seismicity, compressional and strike‐slip fault plane solutions a large, elongated positive free‐air gravity anomaly, Cadiz Gravity High (GCGH). Multichannel seismic profiles across along GCGH, together with bathymetric data, allow us to study in detail tectonic architecture crustal structure Cadiz. upper shelf slope includes main structural domains Betic fold thrust belt. In middle part Gulf,...
On November 1, 1755, the city of Lisbon was completely devastated by combined effect a tremendous earthquake, tsunami waves, and fire. The 1755 earthquake most destructive cataclysm recorded in western Europe since Roman Republic, with an estimated magnitude M w ∼8.5 [ Martins Mendes Victor , 1990] t = 8.5. felt as far away Great Britain Finland. hit many coastal cities along southwest Iberia North Africa, causing heavy destruction Tanger Casablanca.
Controversial evolutionary models have been proposed for the Gibraltar Arc system, a complex interaction zone between Eurasia and African plates. Here we derive new mantle anisotropic constraints from SKS splitting measurements on dense network of about 90 broad‐band stations deployed over South Iberia North Morocco. The inferred fast polarization directions (FPD) clearly show spectacular rotation along arc following curvature Rif‐Betic chain, while located at South‐East edges distinct...
Deep crustal features of the transition between North Iberian mainland and Bay Biscay are constrained from new wide‐angle seismic gravity data. Velocity‐depth models derived far‐offset recordings onshore two N‐S marine profiles, complemented with refraction data inland tested against that fit anomalies. Important lateral variations inferred along margin. In western transect, a Variscan crust is documented across continental shelf, rapid thinning beneath slope marks to oceanic domain. The...
The crustal structure of the northern Gulf California transtensional margin has been investigated by a 280‐km‐long NW‐SE profile, including deep multichannel seismic reflection and densely sampled refraction/wide‐angle information combined with gravity modeling. modeling constrains two thinned areas, corresponding to upper Delfín Tiburón basins. On both sides toward Baja Peninsula Mexico mainland, progressive thickening continental crust is observed. Our results indicate that thickness 19 km...
During the TopoIberia experiment, a total of 26 seismic broadband stations were recording in northern Morocco, providing for first time extended regional coverage investigating structure and seismotectonics southern branch Betic‐Rif arc, its foreland, Atlas domain. Here, we analyze P ‐to‐ S converted waves teleseismic receiver functions to infer gross crustal properties as thickness V p / s ratio. Strong lateral variations are observed throughout region. Crustal thicknesses vary between 22...
The seismic structure of the crust NW Iberian Peninsula, along Cantabrian Mountains and their southern foreland, Duero basin, is investigated from first data set available refraction wide‐angle reflection profiles. velocity‐depth distributions obtained E‐W N‐S transects evidence lateral variations in crustal that can be associated to Variscan Alpine tectonic episodes. western part range, toward hinterland zones, as well basin below sediments, show a similar belt elsewere Europe. total...
The Gibraltar arc and surrounding areas are a complex tectonic region its evolution since Miocene is still under debate. Knowledge of lithospheric structure will help to understand the mechanisms that produced extension westward motion Alboran domain, simultaneously with NW–SE compression driven by Africa–Europe plates convergence. We perform P-wave receiver function analysis in which we analyse new data recorded at 83 permanent temporary seismic broad-band stations located South Iberian...

The mode of crustal thinning in the southwestern margin Iberian Peninsula is investigated along a transect that extends from onshore Iberia to eastern end Horseshoe Abyssal Plain. On areas, structure has been deduced using wide‐angle seismic reflection data, whereas offshore we have used coincident steep and data NE‐SW oriented profile Cape San Vicente In addition, 2D gravity modelling performed validate data. Our model results reveal crust undergoes strong but continuous 31 km less than 15...
