The Central Asia collision zone: numerical modelling of the lithospheric structure and the present-day kinematics
The Central Asia region is dominated by the Zagros orogen in the western sector and the Himalaya-Tibetan orogen in the eastern sector, which resulted from the subduction of the Tethys oceanic lithosphere towards the NNE ...
Geophysical and petrological characterization of the lithospheric mantle in Iberia and North Africa
In this thesis I present a geophysical and petrological study that aims to define the lithosphere structure and the chemical variations in the compositions in the lithosphere mantle in the Iberian plate, the western ...
Anàlisi temps-freqüència de l’estat de polarització del senyal magnetotel·lúric = Polarisation analysis of the magnetotelluric signal in the time-frequency domain
El mètode magnetotel·lúric (MT) és una tècnica geofísica que proporciona la distribució de la resistivitat elèctrica en el subsòl a partir de les fluctuacions temporals del senyal electromagnètic (EM) natural mesurades a ...
Avenços en l’adquisició i interpretació de dades geoelèctriques
La tomografia elèctrica de resistivitat és una tècnica geofísica no intrusiva àmpliament utilitzada en la caracterització de les propietats elèctriques del subsòl i, més recentment, en el seguiment de processos dinàmics, ...
Estudi estructural i estratigràfic del sud d’Andorra
Aquesta tesi es centra en l'estudi estratigràfic i estructural d'un sector de la zona axial del Pirineu, concretament al sud d'Andorra, en què hi afloren roques del Paleozoic que han estat afectades per les orogènesis ...
Processes, time scales and unrest of monogenetic volcanism
Seismic, deformation, and gas activity (unrest) typically precedes volcanic eruptions. Successful volcanic event forecasting depends on the quality of the surveillance network for detecting any changes in volcano behaviour. ...
Caracterización y predicción de desprendimientos de rocas mediante LiDAR Terrestre = Rockfall characterization and prediction by means of Terrestrial LiDAR
En esta tesis se ha llevado a cabo el monitoreo de diferentes escarpes rocosos, que ha permitido la caracterización y la predicción de los desprendimientos de rocas. Esta caracterización y predicción han sido realizadas a ...
Seismic Characterization of the Central Iberian Zone from the Surface to the Upper Mantle
The multi-seismic experiments carried out under the ALCUDIA research initiative include a normal incidence and a wide-angle seismic reflection datasets. These constrain the internal architecture, the detailed crustal and ...
Finite Element Models of Volcano Deformational Systems Having Structural Complexity
The main focus of this work is to build 3-D FEM models with structural complexities in order to simulate volcanic systems in a more realistic way. We use Rabaul as an example to show the application of the methods and ...
Seismic structure of the crust beneath the Rif Cordillera
In this thesis I present a geophysical study that aims to define and characterize the crustal structure in the northern part of Morocco, especially beneath the Rif Cordillera. The geophysical data used in this thesis was ...
The transition between thin-to-thick-skinned styles of deformation in the Western Pyrenean Belt
This PhD Thesis describes the kinematics of the Burgalesa Platform in the Basque-Cantabrian Pyrenees by the integration of i) surface geology; ii) seismic and well data; and iii) vertical axis rotation paleomagnetic studies. ...
Deformación activa en el Pirineo Central: La falla Norte de la Maladeta y otras fallas activas
El trabajo que aquí se presenta parte de la hipótesis de que los terremotos destructivos ocurridos en el Macizo de la Maladeta y su entorno o, al menos, el de 1373 (M=6,2, Olivera et al., 2006), se produjeron ...
Magnetotelluric characterisation and monitoring of the Hontomín CO2 storage site, Spain
The electromagnetic methods are especially interesting for the characterisation and monitoring of geological storage of CO2 sites. The electrical resistivity is a physical parameter that depends on the mineralogical ...
Modelos geológicos en 3D de la isla de Tenerife
Tenerife es una isla volcánica cuya superficie muestra evidencias de grandes deslizamientos y una depresión central (caldera de Las Cañadas) cuyo origen ha sido bastante controvertido. Las dos hipótesis principales se basan ...
Geological and structural controls on La Garrotxa monogenetic Volcanic Field (NE Iberia) and structural controls on La Garrotxa monogenetic Volcanic Field (NE Iberia)
Monogenetic volcanism represents the most common volcano type on Earth. The distribution of it depends in each case on their regional and local tectonic controls. The great variety of eruptive styles, edifice morphologies, ...
Volcanic hazard assessment in monogenetic volcanic fields
One of the most important tasks of modern volcanology, which represents a significant socio-economic implication, is to conduct hazard assessment in active volcanic systems. These volcanological studies are aimed at hazard ...
3D seismic imaging and geological modeling of the Hontomin CO2 storage site, Spain
This thesis is organized as a compendium of three scientific articles, describing the geological characterization of the Hontomín site for Geological Storage of CO2 by means of 3D seismic data, acquired for this purpose, ...
The structure and formation of the Tyrrhenian basin in the Western Mediterranean back-arc setting = Formación y estructura de la cuenca del Tirreno en el contexto de retrarco del Mediterráneo Occidental
In this thesis I present a geophysical study that aims to define the structure and petrological nature of the main geological domains in the Central Tyrrhenian basin, and to investigate the mechanisms involved in their ...
Aplicación del método magnetotelúrico a la caracterización de reservorios: Anticlinal de El Hito (Cuenca) y Sistema Geotérmico de Tenerife
El método magnetotelúrico es una técnica geofísica que permite caracterizar las estructuras del subsuelo en base a la distribución de la resistividad eléctrica. Este parámetro físico es muy sensible a pequeños cambios ...
Estudios de la deformación cortical de la península ibérica mediante observaciones GPS
La península ibérica representa el extremo más occidental del cinturón orogénico Alpino-Himalayo y está caracterizada por la colisión entre la placa africana (Nubia) y la euroasiática. La convergencia entre estas dos placas ...
