Projects GFDRR-DFID GFDRR-DFID Challenge Funds Versión en español English version Share Facebook LinkedIn Overview Anchor 6 Background The Global Facility for Disaster Reduction and Recovery (GFDRR) and the UK Department for International Development's (DFID) competitive Challenge Fund pilots new and innovative approaches to overcoming technical and technological challenges in order to strengthen disaster and climate risk decision-making in developing countries. To this end, this project is supporting the development of data, products, and approaches to support disaster risk management decision-making and build resilience, including through better information, but also strengthening key steps in moving from information to insight and behaviour change. Each challenge is focusing on the development of a database with hazard footprints, exposure information and vulnerability models. The viability of the databases will be demonstrated using exposure data for Tanzania and another DFID priority country. Objectives The project is divided into three components. The British Geological Survey leads the development of a data schema and data for a multi-hazard database (Challenge 1) while GEM and University College London lead the development of a global exposure database (Challenge 2) and open vulnerability platform for evaluating risk (Challenge 3) respectively. GEM also contributes to Challenge Fund 1 and 3. GEM leads Challenge Fund 2 on the development of a global exposure data framework, which includes the physical vulnerability characteristics and exposure taxonomy. The aim is to identify the most important vulnerability characteristics; ways to account for uncertainties in exposure and vulnerability models; type of assets that should be supported by the vulnerability and exposure database; and the most common and useful intensity measure types. The objective of this project is to develop a Data Exploration Tool to promote the ability of a user to access, understand and use hazard, exposure and vulnerability data stored in a format that follows the data schema developed by the Challenge Fund consortia. British Geological Survey (BGS) leads the development of a data schema and data for a multi-hazard database (Challenge 1) GEM Foundation leads the development of a global exposure database (Challenge 2) University College London (UCL) leads the development of open vulnerability platform for evaluating risk (Challenge 3) Various organizations also participated and contributed to the project such as the Geological Survey of Tanzania; Ardhi University (Tanzania); Dar Es Salaam University (Tanzania); DFID Tanzania; Prime Minister's Office - Disaster Management Department (Tanzania); DoMA (Malawi); INGC (Mozambique); Ministry of Energy & Mineral Development (Uganda); ImageCat (USA); Humanitarian OpenStreetMap Team (HOT Indonesia); NSET (Nepal); IDF (Switzerland); UA (Netherlands); NGI (Norway); NOC (UK); CIMA (Italy); and UCL-EPI (UK).

Projects SARA Project South American Risk Assessment (SARA) Versión en español English version Share Facebook LinkedIn Overview Outcomes Training Outreach Photos Publications Anchor 6 Overview South America incorporates some of the most seismically active regions on the planet, where the South American subduction zone generates the forces to create the Andes Mountains and drives the occurrence of destructive earthquakes across Chile, western Argentina, Bolivia, Ecuador, Peru, Colombia and Venezuela. In turn, the high vulnerability of many structures and the high population density of the main cities are factors that contribute to the region’s high seismic risk. In the last two decades alone, over 3,000 fatalities have been reported, and the economic losses have exceeded 30 billion USD (EM-DAT, www.emdat.be ). While expert capabilities exist in these countries to assess earthquake risk, the information, infrastructure, tools, and collaboration networks necessary to develop comprehensive knowledge among scientists and engineers and to move this knowledge into the mainstream of disaster risk reduction activities has been lacking. Objectives The approach is to bring together international best practice tools and methodologies with local expertise and knowledge needed to establish local ownership and define risk assessment objectives and priorities. GEM Foundation combined these elements and focused on developing local capacities across sectors (academic, public and private), across technical disciplines (e.g., hazard, risk, IT), and through the implementation of disaster risk reduction policies and programs. The program of capacity development was initiated in 2013 with the South America Risk Assessment (SARA) Project to bring experts, institutions, and stakeholders from 7 countries to develop a regional assessment of earthquake hazard and risk. GEM provided its OpenQuake earthquake hazard and risk analysis software and other tools and databases freely and openly to all participants. More than 50 of the region’s experts across 17 institutions collaborated to produce critical data sets, develop common approaches, and develop open-source tools for both data collection and interpretation. Collaborators The SARA Project, completed in December 2015, provided the foundation for formal and informal collaborations at many levels and for many purposes. GEM subsequently developed formal partnerships across public and private sectors (e.g., SuraAmerica Insurance, the Geological Survey of Colombia, EcoPetrol), academic partnerships (e.g., EAFIT Univ, Univ del Norte, Univ Catolica Chile), non-profits (e.g., OSSO), and most recently, with municipal governments (Cali, Colombia and Quito, Ecuador), for urban risk assessments. (complete list ) Location Andean Region (Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile and Argentina) Introduction The project was carried out by experts and institutions from the region using to the extent possible open data sets, methodologies and tools such as GEM’s new open source software, the OpenQuake Engine and other OpenQuake tools. The project revolved around 5 modules: hazard, exposure and physical vulnerability, socio-economic vulnerability and resilience, loss estimates and city scenarios. The modules were carried out by a variety of experts/scientists from the region , in collaboration with the project coordinators and, where relevant, the GEM Secretariat. 1. Seismic hazard In early 2013 the Global Earthquake Model (GEM) published seven Requests for Proposal covering topics related to the compilation of basic datasets as well as the creation and calculation of an updated probabilistic seismic hazard input model for South America. Five consortia of South American researchers responded to this request and submitted proposals, which were reviewed in an initial stage by scientists working at the GEM Secretariat, and successively discussed in a meeting in Bogota held in December 2013 at the “Servicio Geologico Colombiano”. 2. Exposure and Physical Vulnerability Development of exposure datasets and vulnerability functions for South America at regional, national and/or sub-national levels have been considered. Modelling of exposure and physical vulnerability in the most earthquake prone countries is the main goal in the first stage of the project. 3. Social Vulnerability and Resilience The social vulnerability component of SARA comprises the development of composite indicators of social vulnerability and resilience along with their robustness testing and validation. The objective is to provide tools and information useful for understanding the potential effects of earthquakes in communities of South America. 4. National and subnational estimation of losses An open and transparent seismic risk assessment for the Andean countries has been performed. A probabilistic approach was followed for the calculation of risk metrics, that includes average annual economic and human loss maps, mean loss exceedance curves per country, and statistics that reveal which building classes are most vulnerable to earthquakes. 5. City Scenarios Following the objectives of SARA, the development of city scenarios is crucial for planning risk management strategies in cities with larger concentration of population and exposed to significant hazard. In this sense, the GEM Secretariat has been seeking collaborations with research groups and governmental stakeholders that will be the end users of case studies in Lima (Peru), Quito (Ecuador), Medellín (Colombia), Iquique, Osorno and Rancagua (Chile).

Projects CRAVE Collaborative Risk Assessment for Volcanoes and Earthquakes (CRAVE) Versión en español English version Share Facebook LinkedIn Overview Outcomes Training Outreach Photos Publications Anchor 6 Summary The need to better understand the existing earthquake and volcano risk led to the establishment of the Global Earthquake Model (GEM) and the Global Volcano Model (GVM) network. GEM, founded in Italy in 2009, has been developing open tools and models to calculate and communicate seismic hazard and risk worldwide. Similarly, the GVM network represents an international community aiming to provide systematic evidence, data and analysis of volcanic hazards and risk on national, regional and global scales working with monitoring institutions to implement the best science and DRR strategies. Both GEM and the GVM network are currently leading international efforts that aim to mitigate the adverse effects from these perils. South America and ASEAN regions have been the target of numerous studies in the last two decades. However, most of these studies only focused on one component of the risk problem (e.g. hazard, vulnerability). Such limitation prevents the development of a comprehensive risk profile to properly inform decision-makers. The CRAVE project, through the current GEM and GVM network tools will offer a timely and unique opportunity to advance the understanding of seismic and volcanic risk in the region. Objectives This project aims to develop a common framework for the assessment of the impact from earthquakes and volcanoes, with an application in three countries located around the Pacific Rim. The activities comprised in this project feature several events to bring together global partners with the mandate to calculate and communicate seismic and volcanic risk, as well as training events to increase the capacity of local institutions in the assessment of their hazard and risk. Collaborators This project includes several partners including the following: British Geological Survey; the Earth Observatory of Singapore (EOS); the University of Edinburgh; the Volcano Disaster Assistance Program (VDAP) of the United States Geological Survey (USGS); and key organizations from the region including: the Colombian Geological Survey; the Philippine Institute of Volcanology and Seismology;(PHIVOLCS); and Badan Geologi (Indonesia). Location Colombia, Indonesia and the Philippines Volcano Scenario tool for OpenQuake The CRAVE project required the implementation of a new calculator in the OpenQuake Engine called ‘multi_risk’, which is able to manage at the same time different types of hazards, specifically ash fall, pyroclastic density currents flow, lava flow and lahar flow, passed as CSV files with headers ‘lon’, ‘lat’, ‘intensity’. The calculator is also able to consider the difference between dry and wet ash by setting the `ash_wet_amplification_factor` parameter in the job.ini file. The output of the calculator is a CSV file with ‘Exposure + Risk’ fields. For convenience we also produced a ‘Total Risk’ output which is simply the sum over the assets of the values in the ‘Exposure + Risk’ output. In order to support other formats used in the volcanic hazard community we prepared tools to convert hazard footprints into the format accepted by the OpenQuake-engine. These tools were included in the Input Preparation Toolkit. [Software ] Volcano Model example Full example of the volcano model developed with the Servicio Geológico Colombiano (SGC).

[Video ] Anchor 1 Anchor 5 Introduction The presentation of the tools and datasets from CRAVE took place in Bogota (Colombia) and Bandung (Indonesia). These events were organized by the Colombian Geological Survey and the Institute of Technology of Bandung. Kick-off Meeting The kick-off meeting took place in Bogota at the offices of the Colombian Geological Survey (SGC) on the 22nd of February 2018. During the meeting the goals of the CRAVE project were presented by GEM, as well as some concepts on seismic hazard, vulnerability and risk modelling. The British Geological Survey (BGS) presented general aspects of volcano hazard modelling and the mission of the Global Volcano Model, the SGC demonstrated how three volcanoes are currently being monitored and how seismic hazard maps have been developed in the past and the Rabaul Volcano Observatory (RVO) presented the current situation in terms of volcano hazard monitoring and assessment in Papua New Guinea. During this event all partners also discussed the way forward, including the division of tasks, case studies, relevant risk outputs and the timeframe for the next workshops. Bandung, Indonesia (20-22 of May) Workshop – IT Bandung With support from the Institute of Technology of Bandung (ITB), the event featured a day of presentations and discussion with representatives from the Center for Volcanology and Geological Hazard Mitigation (CVGHM), the Indonesian Ministry of Public Works, the National Disaster Management Agency (Badan Nasional Penanggulangan Bencana - BNPB), the Meteorology, Climatology and Geophysics Agency (Badan Meteorologi, Klimatologi dan Geofisika - BMKG), the Philippine Institute of Volcanology and Seismology (PHIVOLCS) and the British Geological Survey (BGS). Bogota, Colombia (13-17 of May) Workshop - Geological Survey of Colombia Five days in Bogota provided a fruitful time to share and discuss the national volcanic hazard and risk assessment, as well as risk management challenges in the country. The workshop was divided into two main parts: The first part focused on the technical aspects of volcanic hazard and risk assessment. Representatives from the three mains national volcanological observatories participated in the sessions (Manizales, Popayan and Pasto). The second part of the workshop was conceived for a broader audience, involving stakeholders that contribute to the Disaster Risk Reduction strategy in the country.
