STREVA will bring together researchers from universities, research institutes and volcano observatories, to explore methods for reducing the negative consequences of volcanic activity on communities. We will work both with communities facing volcanic threats and with those responsible for monitoring, preparing for and responding to those threats. Our main partners are volcano monitoring agencies and observatories in Colombia, the Caribbean and Ecuador, and through them, disaster managers and disaster researchers throughout the region, as well as residents of communities at risk. We will use a number of techniques to build links between the project and the wider community, including workshops, running scenario exercises, and using social media to report our results. Our aim, by working collaboratively across different disciplines, is to develop and apply a risk assessment framework that will generate better plans to reduce the negative consequences of volcanic activity on people and assets. Volcanic risk is a complex problem, which we shall understand by investigating a number of volcanoes, at-risk communities, emergencies and policy responses across the region. These case studies will help us to identify common issues in volcanic disaster risk and ultimately develop regional risk assessment processes. These will be crucial for long-term planning to reduce exposure to volcanic hazards. The countries in which we will work are all middle income and face multiple volcanic threats, often in close proximity to large towns and cities. The main focus will be on six volcanic sites across the Lesser Antilles, Ecuador and Colombia. We will begin the project by reviewing the secondary literature on three well monitored and active volcanoes, to analyse what has already been done to understand and reduce risk to the surrounding population. Through in-depth empirical research in these volcanic areas we shall begin to develop, test and apply our new risk assessment framework and methods for application. We will then take these lessons and apply them to three high-risk volcanoes where monitoring and understanding is less advanced. STREVA's work will generate improvements in: (i) methods for forecasting the start of eruptions and changes in activity during eruption; (ii) prediction of areas at-risk (the "footprint") from different volcanic hazards; (iii) understanding of the factors that make people and their assets more vulnerable to volcanic threats; (iv) understanding of institutional constraints and capacities and how to improve incentives for risk reduction By the end of the project, our new knowledge will help us to measure volcanic risk more accurately and monitor how that risk is changing. The practical results will be a strengthening in the capacity of stakeholders at different scales (staff in volcano observatories, local and national governments and NGOs) to produce risk assessments for high-risk volcanoes and use them to improve preparedness and response to volcanic emergencies and build resilience in the surrounding communities through long-term planning. In adopting this approach, STREVA will have real impacts in real places, and will significantly advance the fields of volcanic risk analysis and disaster risk reduction.

The Earth is unique in our solar system in having abundant liquid water, plate tectonics and life. These properties are not unconnected; The evolution of life has depended heavily on water, and water is pumped around the planet by the plate tectonic cycle. Plate tectonics in turn, and its capacity to generate the very continents on which we live, also depends on the existence of water. Subduction zones are the most important "valve" in the plate tectonic system. They form where tectonic plates sink back into the mantle. Here water, along with other volatiles such as carbon dioxide and sulphur, are returned to the deep interior. However, the return is not wholesale. As the sinking plate is subjected to heat and pressure, a large fraction of the incoming volatiles is "sweated off" and added to the overlying mantle where it causes melting. These melts feed volcanoes at subduction zones which are characteristically dangerously explosive. When considered with the earthquakes triggered by the plates scraping past each other and the consequent tsunamis and landslides, it is clear that subduction zones are the most hazardous places on Earth. Yet, these regions also have benefits: the cocktail of fluids travelling with magmas at subduction zones is responsible for transporting and emplacing valuable metal deposits into the crust, and the fine ash distributed by the explosive volcanoes produces nutrient-rich, fertile soils. The importance of cycling volatiles through subduction zones is self-evident. However we still don't really know how it works and what the budgets are of volatiles delivered to the subduction zone, versus those recycled into the lithosphere, hydrosphere and atmosphere compared with those sequestered back into the deep mantle. We propose an innovative multidisciplinary experiment to track volatiles at a subduction zone. Questions to be answered include: How do volatiles influence the types and amounts of magmas generated? How do they control where volcanoes, such as Mt Pinatubo and Montserrat are located and how explosive they are? How do volatiles dictate where ore deposits are formed? How do volatiles mediate the seismogenic behaviour of subduction zones - whether there are large "megathrust" earthquakes like Japan and Sumatra or whether slip is less violent? Our focus area is the Lesser Antilles Arc, which is a special case, because it is one of only two Atlantic subduction zones. Plate formation processes at the slowly-spreading mid-Atlantic ridge produce a much more pervasively hydrated plate than those in the extensively studied Pacific. Furthermore, a laterally varying capacity to carry water in the plate and sediments subducting below the Antillean arc are a likely culprit for the arc's highly variable style and intensity of seismic and volcanic activity. By mapping structural differences along the arc we will be able to pinpoint the effects of variable water input. We plan to use novel seismic approaches complemented by geochemical analyses and integrated using numerical models to identify and quantify where volatiles are in the downgoing plate, where they are released at depth, and how they are transported from the subducting plate through the mantle wedge to the arc. We will use a unique suite of rocks from deep in the crust which have been carried up in volcanoes to help us understand how magmas evolve, and what allows them to concentrate ore metals. Mapped water pathways will be compared with seismic and volcanic activity, as well as with those inferred at other subduction zones. This large research project will be "bookended' on the one hand by an enormous amount of resource; data, samples, expertise and results from previous studies that will provide excellent value for money, and on the other hand a special focus on the societal benefits; informing natural hazard planning, and a better appreciation of how and where economic deposits form.

EULAC Focus addresses the whole set of topics included in the Call. It delivers a significant contribution to the improvement of EU–CELAC relations through a better understanding of the three dimensions selected by the call: cultural, scientific and social. The main objective is that of “giving focus” to these three dimensions of EU–CELAC relations, with a view to determining synergies and cross-fertilization, as well as identifying asymmetries in bi-lateral and bi-regional relations. Research is focused on areas crucial to explain the current state of relations between EU and LAC, and will be pursued at two levels: a) research activities; b) strategic set of recommendations. In order to guarantee high impact, the research is pursued in six interdisciplinary WPs, organized “matricially”. Three are “horizontal ”: Cross-cutting pathways, Towards a common vision for EU–CELAC and Dissemination and outreach. The other three are “thematic/vertical”: Cultural, Scientific and Social Dimension, and not only intersect the horizontal WPs but also interact between them. To achieve the objectives, the project is organized by the multidisciplinary and well balanced consortium of19 members from 15 counties. The consortium represents a unique group of highly competent and experienced institutions, composed specifically for the purpose of this project,comprising, in both regions, Gov Research Agencies, Research institutes, Universities, University Association, and two International European – LA Organizations active in analytical and policy oriented research and dissemination. EULAC Focus builds upon the outcomes of prior mapping conducted at the bi-regional level and will facilitate access to end-users, as well as feeding into the work of the EU-LAC Foundation and informing bi-regional networking activities of the JIRI and T-AP’s work. The number of partners has been carefully defined to ensure project goals and proper diversity, while allowing for efficient project management.

This proposal identifies an opportunity to bring together leading international experts to consider the dispersal and impacts of volcanic ash. A key theme emerging from one of our existing research project (STREVA) is the role that volcanic ash plays in disrupting lives and livelihoods across all scales: from major disruption of international air traffic to the destruction of individual livelihoods via irreparable damage to crops and livestock or health problems. Another (VANAHEIM) is uncovering new insights into the ash loading and subsequent dispersal from eruptive columns. Globally other researchers have started to systematically examine the impacts of ash fall-out on critical infrastructure, buildings, communication, vegetation, soil and human or animal health However we currently do not fully understand several things: (i) localised variance in ash dispersal on the kilometre scale and regional (cross-border) dispersal; (ii) thresholds and timings of the ways in which soils and plants are impacted by ash concentrations; (iii) the impact of ash on human and animal health over both short and long time-scales; and (iv) the role that ash concentration plays in disrupting transportation and communication networks during an acute volcanic crisis. Even more importantly, the impact of these processes on communities affected by eruptions lies in their cumulative effects and interacting processes. We want to consider how to tackle this more effectively, by developing andapplying the very best scientific approaches. Through this International Opportunities Fund we will establish a new team of experts to start to tackle these problems with a multi-disciplinary approach which engages key stakeholders and end users, and paves the way for future long-term collaborations. We are taking a 'problem-based' approach to this issue and will focus on one particular island, but use it to consider general problems. This will help us to focus on the most critical scientific issues and provide a new group of researchers with a common problem on which to build an analysis of future research need. The information from the specific setting (St. Vincent) can be immediately applied in disaster planning and regional contingencies for ash disruption. The network built by this project intends to not only report on its findings relevant to St. Vincent but to use these to apply for research finding that enables a diverse group of experts to make real progress in understanding, anticipating and mitigating against the risks from ash fall.
