News GRII agreement signing with UNDRR, University of Oxford, and GEM Foundation By: Jun 28, 2023 Share Facebook LinkedIn GEM Foundation has signed an important agreement between the Insurance Development Forum (IDF), the UNDRR, and Oxford University to collaborate on the Global Resilience Index Initiative (GRII). The GRII was established to make climate risk data available to governments and financial institutions to inform and foster climate-resilient investments worldwide. GEM’s inclusion in this partnership recognises that GEM’s expertise, tools, data and collaboration framework can also be applied to assessing climate change impacts and risks. I.T. represents an important link for GEM with the climate change risk assessment community. Zurich, Switzerland, 1 June 2023: Today at the IDF Summit 2023, the UN Office for Disaster Risk Reduction (UNDRR), the Insurance Development Forum (IDF), the University of Oxford, and the GEM Foundation signed a new agreement to advance the Global Resilience Index Initiative (GRII) and establish a Global Resilience Hub to help countries, financial institutions and investors, map and quantify their current and future climate and disaster risks and demonstrate the benefits of investing in resilience. The collaboration will prevent leaders from ‘flying blind’ on physical climate risk and focus vital investments on areas of greatest need. Combining the insurance industry’s unparalleled foresight and modelling expertise, with the best UN and scientific data, the GRII will work with financial institutions and governments and capacity building programmes such as the Global Risk Modelling Alliance to improve the metrics and analysis essential to mobilise finance for adaptation and to better understand potential future loss and damage. An Operational Launch is planned for COP28 in Dubai and has been enabled by new in-kind and funding support from Climate Arc, the World Bank and the ongoing support of the UNDRR, UKCGFI, UK Research and Innovation, and the IDF. Further upgrades are being planned for COP29 in Australia assuming additional resources become available. Announced at COP26 under the mandate of UN Special Envoy for Climate Action & Finance, Mark Carney, the GRII provides critical data and metrics to save lives, mobilise finance for adaptation and incentivise resilient development. The initiative has gained remarkable traction as concerns over climate resilience have grown in the wake of recent disasters across both developed and developing countries. The data challenge has required an unprecedented collaboration across public, private and academic sectors combining resources and sharing expertise. GRII will respond to this challenge and the growing demand and will work to provide metrics, tools and guidance to support financial institutions, businesses and governments to increase investment in adaptation. Speaking at the IDF Summit 2023 Summit in Zurich, Switzerland, GRII patron and UN Special Representative for Disaster Risk Reduction, Mami Mizutori, said: “Currently, we know that only about 4 percent of all official development assistance related to disasters goes into prevention; the rest goes into response and recovery. This is not sustainable in the face of growing climate risks. There must be a rebalance towards investing more in prevention. The GRII helps point to where investment is needed and can have the most impact. By directing investments and resources to reduce climate risks before they create disasters, countries can build a sustainable resilient future for all.”By December it is expected that the GRII will provide open-access data to support solutions to some of the biggest challenges at CoP28 including climate adaptation investment and loss and damage implementation. Meryam Omi, Chief Executive, Climate Arc, founding funder of the new Hub, said, “Climate Arc is proud to support GRII’s work to improve the availability of physical climate risk and resilience data. GRII’s open, transparent asset-level data will support public and private financial institutions in accelerating the mobilisation of finance for adaptation and resilience in emerging and developing economies. We look forward to seeing the initiative continue to grow and reach even greater scale and impact in the future.”The worldwide risk modelling collaboration and work with financial institutions is coordinated by a Global Resilience Hub, hosted by Oxford University . Dr Nicola Ranger, Director of the new Hub and Leader, Resilience and International Development at the Environmental Change Institute, University of Oxford, said: “Oxford has a strong record of advancing frontier science to save lives through public private academic collaboration. The data we are collectively building and making available through the Global Resilience Index Initiative is urgently needed to close the gap in investment in adaptation and nature-based solutions to protect people, prosperity and the planet and align finance with climate resilient development. We’re delighted to be working with partners internationally to deliver this important initiative.” John Schneider, Secretary General of the GEM (Global Earthquake Model) Foundation , a public-private partnership that is committed to reducing the risk of earthquakes and other natural hazards worldwide, said: “GEM recognises that the tools for assessing earthquake risk can be leveraged to assist in assessing climate change impacts and risks. Moreover, an understanding of physical and socio-economic vulnerability and the evolution of our natural and built environment are fundamental to understanding all of these risks. It is exciting to be part of the GRI Initiative to bring our collective expertise and information to the table.”The GRII has been coordinated by the Insurance Development Forum the platform co-chaired by the UN, World Bank and Industry to support practical climate resilience measures. The GRII is seen as key to directing financial flows towards resilient investments including homes, schools and infrastructure. Michel Liès, Chair of the Insurance Development Forum and Zurich, said: “We are delighted that the GRII has reached this important milestone in its capabilities, resources and governance. Our thanks to all our partners and supporters who have joined this collective endeavour to solve this grand challenge on the Race to Resilience.” Link to the press release: https://www.insdevforum.org/press-release-un-insurance-and-academic-leaders-sign-agreement-to-draw-upon-insurance-data-and-expertise-to-advance-climate-and-disaster-risk-analytics-and-help-mobilise-finance-for-adaptation/ No images found.

News John Schneider: GEM’s new Secretary General By: Jul 2, 2018 Share Facebook LinkedIn What inspired you to apply for the position of the Secretary General? To me it GEM is a program that is very much needed; it uniquely combines science, engineering, and social science, but it is also pushing the boundaries in the development of methodologies, tools, and open data in a true integration of information, making it available for the common good. GEM is also a bridge between academic science and genuine applications for decision making in Disaster Risk Reduction. Operating at a global scale, the organisation fills a unique niche between research and application - and the world needs more organisations that do that! In March of 2009, when I was trying to get support from Australia to join GEM, we held the first official GEM workshop at Geoscience Australia during the program called GEM1, so I have been involved for a long time with GEM. I have also been on the Governing Board, later as Chair until the end of June last year.Working with GEM, to me brings everything that I have been interested and I have been doing in my career, all together in one place. GEM is a great organisation that is going to be around for a long time and I hope to contribute to that. Can you tell us a little about yourself, John Schneider, the person? I have always been interested in taking new challenges and now I am here with my wife (Jill Dobkin) who joined me to come to Italy and enjoy the life here. Our two children are now grown and have stayed in Australia: our son Bennett is in his fourth year at the Australian National University studying renewal energy systems and physics, and our daughter Margot has just finished high school and is using 2016 as a gap year.I was born and raised in the San Francisco Bay Area and graduated from the University of California at San Diego. I went to graduate school at the University of Wisconsin, where I did my PhD on earthquakes in Bucaramanga, Colombia. From there I did post-doctoral research at the Carnegie Institution for Science in Washington D.C., studying earthquakes Peru, including field work in the Amazonas. From there I worked with the Electric Power Research Institute (EPRI) in California and AON Corporation in Chicago, mainly on earthquake hazard models. In 2000 I moved with my family to Australia, where I was responsible for developing a multi-hazard risk assessment capability for the Geoscience Australia. The program grew to include many natural hazards - earthquake, tsunami, flood, volcanic ash, cyclone and bush (wild) fire - as well as man-made hazards and climate change. We built many open source models for hazard and risk assessment in Australia, and further developed and applied them in a program of capacity building in South East Asia and the Pacific, mainly in the Philippines, Indonesia, Papua New Guinea, and South Pacific islands. What will be the priorities to address in your first months as Secretary General? My main priority is to further develop and implement a plan for organisational sustainability. Working with our partners, the Secretariat can build a solid foundation for the future. The short-term need is to increase sponsorship by approaching specific public and private organisations, and to secure project funding aimed at capacity building and completing the global earthquake model. In the longer term we need to expand our marketing approach to attract other sectors, such as financial, energy, and manufacturing and to gain more traction with donors in the disaster risk reduction sector, particularly in the context of the UN’s new Sendai Framework for Disaster Risk Reduction. The other priority is around making the organisation itself, especially the Secretariat, a more confident and effective organisation. We also need to work on internal processes such as for information management, and roles and responsibilities of staff. Through these efforts, I think we can make GEM Foundation a more cohesive and a stronger organisation moving forward. What is your vision for GEM for the next three years?I see GEM becoming an integral part of the Disaster Risk Reduction community globally, as part of the overall development and application of earthquake and other natural hazards risk assessment capability. It follows then that I see us being better supported and used much more widely in both the public and private sectors. Finally, I see GEM realising its goal to reduce earthquake risk worldwide by developing and implementing risk assessment methodologies, tools, and information. What about the challenges associated with achieving the vision you articulated? GEM does so many things that are fundamental to developing and applying science to make the world a better place, such as:- The delivery of Open Source software and open data;- Development of international collaboration through public-private partnerships;- Reducing the gap between academics and practitioners;- Providing tools that are fit for purpose for decision making;Improving capacity in developing countries;- Building greater understanding of social vulnerability; and- Bridging science, engineering and social science - just to name a few.These are things that are actually much more challenging than integrating hazards into multi-hazard analysis. Through our partners we can add other hazards – that is relevantly easy. The hard part is developing the collaboration network and building the sense of common responsibility and ownership for how we work together and what we do. We now have hundreds of collaborators in nearly 100 countries working with us; and there are now over 1,300 subscribers to the OpenQuake Platform. This is a pretty solid base to work from! I also think GEM is extremely well grounded in its fundamental principles of openness, transparency, credibility and public good. The only question then is in what form GEM will be in the future, not whether it will exist. Although I don’t know the form, I know it will exist in some way because the demand for what GEM does and offers is much needed; so it is really up to us to be successful because we are doing so many things right - we just need a few more champions and a bit more confidence to do it.

Publications Exploring the impact of spatial correlations and uncertainties for portfolio analysis in probabilistic seismic loss estimation Share Facebook LinkedIn Download 2014 | Peer-reviewed The significant potential for human and economic losses arising from earthquakes affecting urban infrastructure has been demonstrated by many recent events such as, for example, L’Aquila (2009), Christchurch (2011) and Tohoku (2012). Within the current practice of seismic loss estimation in both academic and industry models, the modelling of spatial variability of the earthquake ground motion input across a region, and its corresponding influence upon portfolios of heterogeneous building types, may be oversimplified. In particular, the correlation properties that are well-known in observations of ground motion intensity measures (IMs) may not always be fully represented within the probabilistic modelling of seismic loss. Using a case study based on the Tuscany region of Italy, the impacts of including spatially cross-correlated random fields of different ground motion IMs are appraised at varying spatial resolutions. This case study illustrates the impact on the resulting seismic loss when considering synthetic aggregated portfolios over different spatial scales. Inclusion of spatial cross-correlation of IMs into the seismic risk analysis may often result in the likelihood of observing larger (and in certain cases smaller) losses for a portfolio distributed over a typical city scale, when compared against simulations in which the cross-correlation is neglected. It can also be seen that the degree to which the spatial correlations and cross-correlations can impact upon the loss estimates is sensitive to the conditions of the portfolio, particularly with respect to the spatial scale, the engineering properties of the different building types within the portfolio and the heterogeneity of the portfolio with respect to the types.

News CRAVE project kicks off in Bogota, Colombia By: Jul 2, 2018 Share Facebook LinkedIn The USAID project – Collaborative Risk Assessment for Volcanoes and Earthquakes or CRAVE successfully kicked off with a workshop in Bogota, Colombia on February 22-23, 2018. Participants came from the British Geological Survey, the Volcano Disaster Assistance Program (VDAP) of the United States Geological Survey (USGS), the Colombian Geological Survey and the Rabaul Volcano Observatory of Papua New Guinea. The project also includes the participation of the Philippine Institute of Volcanology and Seismology (PHIVOLCS), the Earth Observatory of Singapore (EOS) and the University of Edinburgh. The kickoff meeting covered several topics, including the identification of relevant hazard and risk information for decision-makers, data needs for volcano and earthquake hazard assessment in the pilot areas (Colombia and Papua New Guinea), challenges in the harmonization of software, models and datasets, and available modeling tools for the assessment of the impact from these geo-hazards. Marta Cavalche of SGC highlighted the importance of expanding the assessment beyond hazard after a discussion that most of the available assessment software is only for hazard. The project anticipates that communicating earthquake and volcanic risk can be a challenging task due to other competing social issues, and the lack of resources. However, Vitor Silva of the GEM Foundation points out that “When resources are limited, and they are always limited, we cannot afford to tackle one problem at a time. A multi-hazard and multi-disciplinary approach to disaster risk reduction better utilizes available resources.” Despite several aspects that need to be addressed such deciding on a uniform assessment framework, data format, and data availability, participants identified points of common work, as well as strategies to achieve the objectives set by the project. CRAVE is funded by USAID and will run for 18 months to develop a common framework for the assessment of the impact from earthquakes and volcanoes, with an application to a few locations in the Philippines, Papua New Guinea and Colombia.The kickoff meeting also appeared on SGC’s website article: Reunión inicial del proyecto CRAVE.

Publications Probabilistic seismic risk assessment of India Share Facebook LinkedIn Download 2020 | Peer-reviewed This study presents a comprehensive open probabilistic seismic risk model for India. The proposed model comprises a nationwide residential and non-residential building exposure model, a selection of analytical seismic vulnerability functions tailored for Indian building classes, and the open implementation of an existing probabilistic seismic hazard model for India. The vulnerability of the building exposure is combined with the seismic hazard using the stochastic (Monte Carlo) event-based calculator of the OpenQuake engine to estimate probabilistic seismic risk metrics such as average annual economic losses and the exceedance probability curves at the national, state, district, and subdistrict levels. The risk model and the underlying datasets, along with the risk metrics calculated at different scales, are intended to be used as tools to quantitatively assess the earthquake risk across India and also compare with other countries to develop risk-informed building design guidelines, for more careful land-use planning, to optimize earthquake insurance pricing, and to enhance general earthquake risk awareness and preparedness.

News TREQ Project Updates: Site Effects Modelling and Urban Exposure Models By: Jun 3, 2021 Share Facebook LinkedIn Site Effects Modelling and Urban Exposure Models Over the past year, TREQ has made significant progress in the risk and hazard assessment for the selected cities: Santiago (Dominican Republic), Quito (Ecuador) and Cali (Colombia). This includes compiling and preparing existing PSHA models for hazard calculations; and the development of detailed exposure and vulnerability models. Urban Hazard Assessment For Santiago de los Caballeros, Dominican Republic, the project team worked with local experts from the National Geological Survey (SGN) and the Autonomous University (UASD) at compiling, reviewing, and preparing a new seismic catalogue to be used in hazard calculations for Hispaniola. The team has also prepared the national database of active faults, using the information compiled in the CCARA project and additional information provided by SGN (i.e. data and reports). The project is now using the catalogue and fault data to construct the national probabilistic seismic hazard model for the Dominican Republic. A preliminary version has been completed, and construction of the final model is underway. For Cali, Colombia, the project improved the national model proposed by Arcila et al. (2020) by adding a new fault located underlying the city (i.e. Cauca-Cali-Patia fault), consistent with the seismic zonations used in the microzonation study for Cali (Ingeominas-Dagma, 2005), and the Colombian building code (AIS, 2009). For Quito, Ecuador, the project selected the model of Beauval et al. (2018), composed of shallow and subduction seismic sources characterized using an ISC-based catalogue and active shallow fault sources considering geodetic slip-rates assuming a 50% of aseismic slip. Now, the project is consolidating the available geological, geophysical, and geotechnical data for each of the three cities needed to compute site-response (amplification of ground shaking in surficial sediments (or soil) during an earthquake). Future versions of the OpenQuake engine will support the calculation of site response through detailed site/soil amplification functions and their corresponding uncertainty. Urban Risk Assessment GEM has already developed exposure datasets at the subnational level in the Dominican Republic, Colombia and Ecuador. However, the risk assessment activities planned within the context of TREQ require exposure datasets at urban scale. To this end, GEM has focused on the development of high-resolution exposure models. These have been established with support from the municipal governments in each city, namely, Oficina de Planeamiento Territorial (Santiago de los Caballeros), Oficina de Planeación y la Secretaría de Gestión del Riesgo de Emergencias y Desastres (Cali), and Dirección Metropolitana de Gestión del Riesgo (Quito). The exposure models were developed using dedicated databases from each city. These databases include the most recent information from the census, cadaster, and urban planning offices. As a result, they feature better estimates for the number of occupants, building counts, replacement costs and vulnerability classification of structures. In close collaboration GEM and the USGS are validating the exposure models by means of assessing the potential impacts of earthquake scenarios at a neighborhood level. The objective is to use recorded/estimated damage and economic losses from relevant historical scenarios to assess the accuracy of the exposure and hazard model data. The risk metrics that are being analyzed in each city include building damage, economic losses and fatalities. No images found. GALLERY 1/0 Gallery VIDEO RELATED CONTENTS
