The purpose of this PhD thesis is to evaluate the volcanic risk associated with San Miguel Volcano, one of the most active volcanoes of El Salvador, through assessing volcanic hazard, that is, identify how a volcanic system ...
[eng] The Mediterranean region is very sensitive to modern climate variability. Located in a temperate subtropical climatic zone and surrounded almost entirely by large continental masses, the Mediterranean region climate ...
The main objectives of this PhD thesis are the identification of the snow avalanche release areas and the snow avalanche flow regime characterization with the use of seismic data. We aim to search for new methods for ...
La predicción de las avenidas torrenciales en zonas de montaña está limitada por la complejidad de las inestabilidades meteorológicas que las generan (tormentas convectivas con un fuerte efecto orográfico), la rápida ...
In this thesis, the 3D structure and kinematics of the locally and mildly inverted Lower Austria Mesozoic Basin beneath the Alpine-Carpathian fold-and-thrust belt is described. This study has been carried out by the ...
The Maestrat basin was one of the most subsident basins of the Iberian Rift System, which experienced two main rifting events: Late Permian-Late Triassic and Late Jurassic-Early Cretaceous. Its inversion during the Cenozoic ...
Aquesta tesi té com a objectiu modelitzar el paleoclima del trànsit Eocè−Oligocè de la Conca de l’Ebre i conèixer com aquest canvi afectà a la flora local. Aquesta caracterització paleoclimàtica s’ha obtingut a partir de ...
[eng] Plastic waste is a global threat to ecosystems, especially in marine systems where most of the threats from plastics occur. The Mediterranean Sea is one of the most polluted basins due to marine litter, particularly ...
Monitoring the elastic properties of the subsurface is of a special interest to mitigate the associated risk with natural and artificial hazards. In the last decade, coda-wave interferometry has become an excellent tool ...
[eng] Our planet is impacted by diverse natural and human-induced events, including weather-related events (floods, droughts, forest fires, etc.) and geological events (landslides, earthquakes, volcanic eruptions, etc.). ...
This thesis aims at improving the current understanding of the geodynamic controls on tectonic deformation during plate collision, using the Cenozoic evolution of Iberia as a case scenario. Despite the vast efforts during ...
El objetivo principal de la Tesis realizada ha consistido en el conocimiento de la fauna de organismos edáficos y acuáticos preservados como bioinclusiones en ámbar español de los yacimientos albienses de Peñacerrada I y ...
This study combines cave speleothems and marine sediments to gain an insight into the climate variability of the Iberian Peninsula (IP) and its surrounding seas associated with previous warm interglacial periods. In ...
The Eastern Betics Shear Zone (EBSZ) is one of the most active fault systems in SE Spain. It has caused damaging earthquakes in historical times, including the 2011 Lorca earthquake, which evidenced that the regional hazard ...
This thesis addresses the tectonic and paleogeographic evolution of the SW Iberia Margin from the Mesozoic rifting stage to the post-rifting collision of Late Cretaceous through Miocene times and transpressive stages of ...
Donada l’alta sensibilitat de la regió central de la Mediterrània occidental a la variabilitat climàtica, s’han reconstruït les condicions de la mar superficials i profundes així com de les atmosfèriques pels darrers 2.700 ...
The thesis presented here spins off from the 2-year oil-industry project entitled “Salt Tectonics Modelling at Kuqa Foreland Fold and Thrust Belt, Tarim Oilfield” that was a collaboration between the American-based company ...
[eng] Although there is certain consensus on the Middle Jurassic to Present evolution of the Central Atlantic, the Early Jurassic rift to drift transition stage is still under discussion. Through the interpretation of ...
The Eocene South-Pyrenean foreland basin provides a continuum of outcrops representing a Source to Sink sediment routing system from subaerial canyons to deep marine environments. On this context, the specific objective ...
[eng] The Hawaz Formation is a Middle Ordovician siliciclastic succession which extends for hundreds of kilometres across North Africa. This thesis uses a subsurface-based approach, mainly utilizing well data, complemented ...
