La conexión plutónico-volcánica se ha postulado principalmente en base a enfoques petrológicos, geoquímicos, geocronológicos, y geofísicos, y modelos teóricos, todos ellos proporcionando evidencia indirecta, aunque de momento se han ofrecido muy pocos ejemplos de campo de dicha conexión. La razón es que la mayoría de los terrenos volcánicos bien expuestos son demasiado jóvenes para que la erosión o la tectónica hayan exhumado sus raíces plutónicas más profundas, mientras que los terrenos plutónicos son demasiado viejos para preservar los posibles equivalentes volcánicos. El volcanismo del Pérmico Superior-Carbonífero-Inferior del Pirineo catalán ofrece una excepción a esta regla general, y expone varias rocas plutónicas, subvolcánicas y volcánicas contemporáneas y cogenéticas, ofreciendo así un buen ejemplo de campo de la existencia de dicha conexión plutónico-volcánica. La reconstrucción estratigráfica y estructural basada de este complejo plutónico-subvolcánico-volcánico, así como las nuevas edades radiométricas U-Th en circones, demuestran que hubo una relación tiempo-espacio entre todos ellos, ofreciendo así uno de las pocas evidencias directas de la existencia de la conexión plutónico-volcánica

Ocean Island Volcanoes (OIVs) and seamounts are one of the most common, prominent and rapidly formed but least studied (from a geological/volcanological point of view) features on Earth. OIVs, which represent only the summit section of a much larger volcanic edifice rising up from the sea floor, are highly vulnerable to geological hazards such as volcanism, seismic activity, mass wasting (caldera formation), landslides and rockfalls, and tsunamis. Specifically, a volcanic eruption on an OIV can mainly have a substantial impact on the local population, infrastructure and economy. It is then essential understand the characteristic behaviour and the ages of the recent eruptions of the volcano to enhance the capacity to identify future geological hazard processes such as eruptions, tsunamis, etc. In other words, to forecast how a volcano will behave, it is essential to identify, map and analyse the deposits from past eruptions and determine the ages of those deposits. However, this becomes more challenging on Ocean Island Volcanoes that have not experienced recent eruptions, such as Easter Island (Chile), but which may still pose a significant risk of future eruption.
This proposal focuses on Easter Island (Rapa Nui or Isla de Pascua), an isolated southeast Pacific island with 7.750 inhabitants, that receives more than 100.000 tourists per year. This island has been catalogued as one of the 92 active volcanos of Chile by the Chilean mining and geological service, occupying the 46th position in its Volcanic Risk ranking. It was included taking into account the recent activity focused on Terevaka volcano and its peripheral vents and other factors as the population and infrastructures exposure and its high amount of visitors per year. Nevertheless, there is still a lack of robust geochronology and volcano-stratigraphy and morphometry for Easter Island, especially for these most recent eruptions. Therefore, a comprehensive study of its Holocene eruptions regarding their styles, a more accurate age determination, and a well identification of submarine volcanic centres around the island is still pending to evaluate its potential volcanic hazard.
The main aim of this project is to identify and study the most recent eruptions of Easter Island, both onshore and offshore. This will allow understanding how and when they took place in terms of volume, diverse morphometric parameters, styles and their ages which will verify if the island is still active. To identify and characterize the style of the most recent eruptions (Holocene- last 11.700 Kyr) on the island it is planned to conduct geomorphologic and morhometryc analyses of subaerial and submarine recent volcanic deposits with and integrated onshore/offshore approach. Also, volcano-stratigraphy for the most recent cones and associated deposits onshore, with special attention to those hydrovolcanic eruptions will be analysed. To determine the number of Holocene eruptions on the island, 14C (for charcoal), 40Ar/39Ar (for rocks) techniques will be used. Moreover, we will identify and date tephras of lacustrine sedimentary records of the Rano Raraku, Rano Kao lakes and the Rano Aroi peat bog related to recent eruptions.
A likely future eruption on the island or near its coasts would have negative and serious consequences; therefore, it is essential to undertake this scientific research aimed at improving the knowledge of the processes and their potential impacts. Furthermore, this study will also contribute to understanding the overall evolution of an interoceanic volcanic island whose results can be compared with other more studied OIVs in the world. In addition, this project will support undergraduate and graduate students, for whom this study will comprise most of their dissertation research, being an extraordinary opportunity for them. Moreover, this study will foster ongoing international collaboration, providing a pipeline for future student and faculty exchange, and will promote outreach educational experiences for the community, as well as more specialized seminars.

The EVE project aims at facilitating the interaction and cooperation between scientists and Civil Protection Agencies (CPs) to timely anticipate to volcanic disasters. Built upon the previous EC ECHO funded project VeTOOLS, the aim of EVE is to combine the knowledge on the past eruptive behaviour of the volcanoes with the analysis of real time monitoring in order to construct the European volcano EWS.

EVE will offer an easy and rapid way to forecast in real time how, when and where a new eruption may occur, thus allowing to predict the most probable eruption scenarios and their potential impacts.

EVE will facilitate scientific and technical cooperation at regional and international scales by defining common actions and protocols to forecast volcanic scenarios and their potential impacts, in real time during a volcanic crisis.

EUROVOLC will construct an integrated and harmonized European volcanological community able to fully support, exploit and build-upon existing and emerging national and pan-European research infrastructures, including e-Infrastructures of the European Supersite volcanoes. The harmonization includes linking scientists and stakeholders and connecting still isolated volcanological infrastructures located at in situ volcano observatories (VO) and volcanological research institutions (VRIs). EUROVOLC will overcome fragmentation at various levels, including community, project and discipline fragmentation by addressing four main themes: Community building, volcano-atmosphere interaction, sub-surface processes and volcanic crisis preparedness and risk management. Examples of networking activities under these themes include collaboration and networking between VOs, VRIs and civil protection agencies, networking of atmospheric gas and aerosol observations as well as observations of subsurface processes, and initiation of access to multidisciplinary observations from Krafla Volcano Laboratory as a test bed. Joint research activities include production of services to initialize volcanic ash transport and dispersal models during eruptions, integrated modelling of pre-eruption data, and a complete catalogue of European Volcanoes. Trans-national access to European Volcano observatories will be facilitated and virtual access to various modelling and assessment tools for responding to volcanic unrest and eruptions will be offered. Through these activities EUROVOLC will integrate the European volcanological community and open up and provide a wider, simplified, and more efficient access to key, multidisciplinary European research infrastructures located at leading VOs and VRIs to conduct improved volcanological research, drive best practice at volcanological observatories and open pathways for enterprise to better exploit georesources in volcanic areas such as geothermal energy.

Geomorfología de las Islas Volcánicas Oceánicas Chilenas y Montes Submarinos: Mejorando la comprensión de su origen, evolución y peligros potenciales.

El agua subterránea es una fuente clave para nuestra supervivencia. Ésta se almacena en
formaciones geológicas compuestas por rocas de diferentes propiedades llamadas acuíferos. El
cambio climático puede reducir la disponibilidad de estas aguas subterráneas minando las
reservas de los acuíferos.
El presente proyecto tiene como fin realizar actividades para concientizar y promover el
conocimiento de los acuíferos, y cómo éstos interactúan con el medio dependiendo de las
propiedades de la roca o minerales presentes en la zona. Para ello, se desarrollará una
aplicación móvil como herramienta de identificación de rocas y minerales, donde cada muestra
estará descrita incluyendo información de sus propiedades (composición, porosidad, etc.), con
un modelo 3D de la muestra vinculada al tipo de acuífero. Esta app será presentada en
actividades de divulgación donde se mostrarán los distintos tipos de acuíferos, las rocas que los
forman y cómo los minerales pueden actuar como contaminantes naturales en ellos. La
aplicación será testeada con una institución de educación asociada y se pretende pueda ser
parte del patrimonio tecnológico de la UOH.
