| The aim of this coordinated project is to identify, characterise and constrain the main volcanic hazards in Tenerife, which represents the area of the Canarian archipelago with the associated highests potential risk. The project is based on the results from the EU project Teide European Laboratory Volcano which has allowed to determine the volcanological evolution of Tenerife during the last 2 Ma. The objective of the coordinated project include: the estimation of the eruption frequency of the Teide-Pico Viejo complex; the characterisation of its present and future feeding system; the characterisation of the gravitational colapse processes associated with the central volcanic complex; revision of the historical volanism and its effects; the identification of the main geographical controls on the emplacement of hazardous volcanic flows; and, finally, the identification of the main risk zones according to the predicted volcanic and related natural hazards, are the main goals of this project. |

The main objective of this research project is to improve our knowledge of the subsurface geology of central Tenerife based on a detailed study of surface geology, the geology of the water tunnels and wells, geological information from 2500 m deep, new continuous-coring drillhole and geophysical surveys specifically designed for this purpose. This would provide the geological basis for a future hydrogeological planing and for a detailed evaluation and monitoring of natural hazards (volcanism, seismicity, sector collapses) in Tenerife. This research project would represent a significant benefit for the socio-economic and environmental development of Tenerife as it directly addresses on several fundamental aspects such as hydrogeological planing and mitigation of natural hazards from improving understanding of the internal geological structure of the island which controls both the distribution of ground water and the characteristics of geological hazards present in Tenerife. The results from this study will be of general applicability not only to other Canarian islands but also to many volcanic ocean islands.

The objective of the present proposal is to develop a training network so as to help fill the skills gap in Information Technology, whether in the context of environmental concerns (mitigation of seismic or volcanic risk) or that of hydrocarbon production. This network will associate on the one hand a world class service company (Schlumberger) involved in various field measurements for the oil industry and which has already developed an effective intranet communication system between its various research, development and production centers throughout the world and, on the other hand, five university centers, one of which (INSA) has a strong experience in Information Technologies while the other ones (IPG-P, ENS-Paris, CSIC and UPSL) are renown centers in Earth Sciences.
Determinación de las condiciones preeruptivas de magmas fonolíticos y su aplicación a la evaluación y prevención del riesgo volcánico en Tenerife (FONOTEN)
MCyT
28-12-01 al 27-12-2004
Financiació del Grup de Vulcanología: 15 Mpts
The present research project is addressed to determine the pre-eruptive conditions (P, T, volatiles content and composition) of phonolitic magmas from Tenerife by using experimental petrology, in order to obtain the input parameters necessary to constrain the available physical models which predict the eruptive behaviour of these magmas and, consequently, to precisely assess the potential risk of such volcanic eruptions in Tenerife. The project will mainly focus on the study of the Teide-Pico Viejo complex, the active central phonolitic system, which imposes the main volcanic risk for the island of Tenerife. The present research project is base on the results obtained from previous studies, which have permitted to obtain a general picture of the volcanological evolution of the phonolitic central complex and of its cyclicity, as well as to characterise the its eruptive activity and potential hazards, also allowing to develop the first predictive physical models of its future activity. However, the same previous results also point our the necessity of obtaining precise data on the pre-eruptive conditions of phonolitic magmas from Tenerife, as it is proposed in this research project, if we want to carry out an accurate forecasting of future phonolitic eruptions and of their possible effects. The project includes the use of experimental petrology and related techniques to obtain the pre-eruptive conditions of phonolitic magmas from Tenerife, using a set of representative samples of phonolitic eruptions; the elaboration of numerical models on the dynamics of these eruptions; and simulations of their effects using an information systems specifically developed for this purpose.
Processes and timescales of magma evolution in volcanic systems (ERUPT)
Unió Europea
1-10-02 a 30-09-05
Financiació del Grup de Vulcanología: 115.000 Euros
The objetive of ERUPT is to provide new methodologies to relate the characteristics of volcanic rocks to the conditions leading to their eruption. Extending the volcanological constraints to integrate the geochemical and physical record of magma differentiation that is preserved in the rocks is the underlying principle of this proposal. The approaches proposed will enable us to estimate the rate at which magma differentiates, the conditions (pressure, temperature, volatile content) of magma storage and the architecture, in terms of relative volumes, of the magma storage system. These factors all affect the potential "risk" associated with a given eruption.

This research project aims to establish a detailed structural map of Tenerife and to determine its current stress field, using published data, new surface and subsurface structural data that will be obtained from detailed mapping, geophysical logging and 3D imaging in water wells and boreholes, paleoflow determinations in sheet intrusions, and information of focal mechanism of recent earthquakes. This will provide a good knowledge on the tectonic and stress field evolution of Tenerife and will allow to characterise the influence of the main tectonic lineament on volcanism, seismicity, slope instability and groundwater resources distribution.

The main goal of presents project is to characterise the physical volcanology of the Cabo de Gata calc-alkaline volcanism and, consequently, to cover the lack of knowledge on that topic. It is a basic research project, with a strong field work component, which main objectives are: 1) to establish the volcanic stratigraphy and facies reconstructions of the area, at the vents and eruptions scale; 2) to determine the eruption mechanisms and to quantify the corresponding eruption parameters; and 3) to characterise the structure and dynamics of the related volcano-sedimentary basins.
Riesgos geológicos en Tenerife: analisis de susceptibilidad y peligrosidad (TENERISK)

1-10-2006 a 31-09-2009
Investigadora Principal: María José Jurado
The present project aims to develop a probabilistic analysis of the geological risk on Tenerife. It will estimate the susceptibility and hazard of the potentially dangerous geological processes (volcanism, seismicity, and sector collapses). The project will revise the existing geological and geophysical data and obtain additional necessary data to complete a GIS database on Tenerife. These data will be used as input parameters to run simulation models of the hazardous geological processes, thus obtaining a wide range of possible scenarios. After that the probabilistic analysis will be performed using a Bayesian approach, and this will lead to the quantitative estimation of the geological susceptibility and hazard on Tenerife. This is an unavoidable step to quantify the geological risk on Tenerife and is fully necessary for an adequate land-planning, for the development of emergency plans, and for the preparation of educational programmes aimed to show the Tenerife society the reality of its territory.

Resumen: This project targets specifically the quantification of the thermal history of rheomorphic ignimbrites during their late-stage flow processes on Gran Canaria using calorimetric relaxation geospeedometry. By determining the cooling rates across the glass transition at the flow base, this study will provide for the first time direct quantification of the temperature-time path in rheomorphic ignimbrites. As a result we will obtain a clearer picture on hazards associated with rheomorphism of ignimbrites, which have up-todate been relatively poorly constrained. This bilateral project involves detailed fieldwork, laboratory-based research and computational modelling and provides excellent training opportunities for research students in both participating institutions.
