The convergence zone of the NE-SW complex comprising the Gulf of Cádiz and the Alboran Sea, at the Eurasian-Nubian plate boundary, is frequently affected by seismic activity, caused by submarine long-strike strike-slip fault systems and arcuate fold-thrust systems found in the region. This has resulted in moderate to high magnitude earthquakes, including tsunamigenic earthquakes, and the area has also experienced tsunamis due to major earthquakes and gravitational landslides. This study carries out a Seismic Hazard Analysis, for bedrock conditions, of the marine area between the W of the Gulf of Cádiz and the E of the Alboran Sea in the Ibero-Maghrebian region, based on a deterministic approach, considering areal seismogenic sources. For the estimation of the seismic hazard, a Visual Basic script based on Excel has been used, which has been improved. The results obtained show that the most probable Peak Ground Acceleration (PGA) ranges from 0.2 to 0.4 g, although it can reach up to 1.0 g in certain areas. These results highlight the need for a detailed study of the distribution of seismic hazard in submarine areas, given the significant values of accelerations that can occur. This work is the first comprehensive deterministic seismic hazard assessment carried out in the Ibero-Maghrebian region and aims to take a first step to promote seismic hazard studies in marine areas, whose results can provide relevant information given the implications of earthquakes in the genesis of other natural hazards such as tsunamis and submarine landslides.

Las Loras UNESCO Global Geopark (UGGp) is geologically diverse, particularly in relation to water-derived features: springs, karst springs, travertine buildings, waterfalls, caves. In this work, the interactions between geology, geomorphology, structures and hydrogeology are analyzed. These four components are the fundamentals of geodiversity and their interactions provide a conceptual model of hydrogeological functioning at Las Loras UGGp. The most plausible hypothesis is that the system is formed by two superimposed aquifer systems, separated by an aquitard formed by Lower Cretaceous material. The deep lower aquifer formed by the Jurassic limestones only outcrops on the northern and southern edges of the Geopark and in a small arched band to the south of Aguilar de Campoo. It forms a basement subject to intense deformation. The upper aquifer system, formed by outcropping materials from the Upper Cretaceous, is a free aquifer. It is formed by a multilayered aquifer system that is highly compartmentalized by the very disturbed geomorphology of the landscape, constituting each moorland and each lora, an individualized recharge-discharge system. This model explains the base level of the rivers, the abundant number of existing springs and the permanent nature of some rivers, providing the keys to understand the bases of the geoconservation of a rich geological heritage linked to the active processes of the water cycle.

p. 715-736, Tras el terremoto de Haití de 2010 dio comienzo una iniciativa para tratar de entender mejor los efectos de los terremotos en la República Dominicana, en particular en la ciudad de Santiago de los Caballeros, segunda más importante del país. Santiago ha sufrido varios terremotos devastadores, en 1562 la ciudad fue reconstruida en un nuevo sitio al sur de la falla responsable. El daño debido a un terremoto ocurre asociado a un conjunto de factores, entre ellos, la aceleración del suelo, que por lo general se señala como el principal o como la clave para explicar la mayor parte de los efectos. La aceleración del suelo varía dependiendo principalmente de la distancia al epicentro, de las propiedades del suelo y de la topografía. En cuanto a la distancia, es de esperar menor aceleración conforme aumenta la distancia al epicentro. De otra parte, suelos con diferentes características dan lugar a diferentes respuestas. Los efectos de la topografía aún no se comprenden bien. El efecto de la atenuación de la distancia en un radio de unos pocos kilómetros suele ser mucho menos relevante que el efecto de la variación en las propiedades de los suelos. Este artículo recoge los resultados obtenidos de los estudios de peligro sísmico y microzonificación sísmica en la ciudad de Santiago de los Caballeros: i) cuantificación del peligro sísmico regional debido a la falla septentrional; ii) un nuevo mapa geológico y iii) la cartografía de zonas de respuesta sísmica homogénea y susceptibilidad a la licuefacción, Instituto Geológico y Minero de España, España, Bureau de recherches géologiques et minières, Francia, Servicio Geológico Nacional, República Dominicana, Departamento de Geología, Universidad de Atacama, Chile

The vast amount of information and data necessary for comprehensive hazard and risk assessment presents many challenges regarding the lack of accessibility, comparability, quality, organisation and dissemination of natural hazards spatial data. In order to mitigate these limitations an interoperable framework has been developed in the framework of the development of legally binding Implementing rules of the EU INSPIRE Directive1* aiming at the establishment of the European Spatial Data Infrastructure. The interoperability framework is described in the Data Specification on Natural risk zones – Technical Guidelines (DS) document2* that was finalized and published on 10.12. 2013. This framework provides means for facilitating access, integration, harmonisation and dissemination of natural hazard data from different domains and sources., JRC.H.3-Forest Resources and Climate
