News OQ Engine used in the UNDP Risk Atlas Project for Rwanda By: Jul 2, 2018 Share Facebook LinkedIn Rwanda is a country prone to a wide range of natural hazards that every year put a strain on the most vulnerable communities and take a considerable toll both in terms of economic losses and human lives. In 2013 MIDIMAR (Ministry of Disaster Management and Refugees Affairs) in collaboration with UNDP launched the Risk Atlas Project (2013-2018), funded by the ACP-EU-WB (Africa Caribbean Pacific – European Union, World Bank) aimed at comprehensively assessing existing risks so as to enhance risk management capacity at a national level. We recently learnt that the OpenQuake Engine was used for the earthquake hazard assessment of Rwanda and consider it a step in further strengthening the capability of communities and local experts to leverage advanced resources and apply them to meet their needs. The project involved a team of national/regional consultants with coaching and technical backstopping by UNDP Disaster Risk Assessment specialists from the Headquarter and was led by MIDIMAR and other governmental institutions. Georges Mavonga, former Head of Department of Seismology at the Volcanic Observatory of Goma, was among the regional consultants. In 2012 Georges was trained by GEM scientists on the use of the OpenQuake-engine, which allowed him to train in turn his team and ease the entire assessment process. No images found.

Publications The European Seismic Risk Model 2020 (ESRM 2020) Share Facebook LinkedIn Download 2019 | Peer-reviewed This study describes the development of the various components of the European Seismic Risk Model 2020 (ESRM2020) which will be able to generate, using open-source software developed by the GEM Foundation (the OpenQuake-engine), a number of Europe-wide risk metrics including average annualised human and economic losses (AAL), probable maximum losses (PML), and risk maps showing the losses for specific return periods or scenario events. The latest developments towards pan-European exposure models for residential and non-residential buildings and fragility/vulnerability models for damage, economic loss and casualty assessment will be presented. For engineered buildings within the exposure model (reinforced concrete, steel), a simulated design is undertaken using the key aspects of seismic design codes in force across Europe over the past 100 years. The designed MDOF building is then transformed to a SDOF model and nonlinear dynamic analyses are run using a large number of ground motion records, after which cloud analysis is used to develop the fragility functions. For non-engineered buildings (unreinforced masonry, confined masonry, adobe), the SDOF models have been directly developed from simplified formulae, experimental tests and previous studies. Collaboration from local experts at various stages of the model development, initiated through workshops, is an important component of the model, as well as the extensive calibration and validation.

News Educating for Tomorrow: How GEM Supports the Next Generation’s Disaster Preparedness By: Oct 9, 2024 Oct 13, 2024 Share Facebook LinkedIn The International Day for Disaster Risk Reduction (IDDRR) 2024, themed “Empowering the next generation for a resilient future,” highlights the crucial role of education in safeguarding children and youth from escalating disaster risks. As climate change intensifies the frequency and severity of natural hazards, ensuring that educational institutions are resilient and that young people are equipped with essential disaster risk management knowledge becomes increasingly vital. “For this year's International Day for Disaster Risk Reduction, we are calling on countries to protect and empower children and youth through education. We must ensure that all schools are disaster-resilient and retrofit those at risk. Children must be equipped with knowledge about hazards and disaster risk management, and countries should endorse the Comprehensive School Safety Framework 2022-2030. If we achieve 100% school safety by 2030, we will be acting responsibly toward future generations.” - Kamal Kishore, Special Representative of the Secretary-General of the United Nations Office for Disaster Risk Reduction (UNDRR) https://www.youtube.com/watch?v=dQKgBQ7Mbnc https://youtu.be/dQKgBQ7Mbnc?si=ocGaomK9WZlZSeRE GEM's Contributions While the Global Earthquake Model (GEM) Foundation does not directly focus on youth-specific activities, our broader projects and activities support the goals of IDDRR 2024. Initiatives such as the FORCE Project , which enhances earthquake risk modeling and communicating hazard and risk information effectively, and the TREQ Project , which promotes public understanding of earthquake risks by focusing on capacity building and effective risk communication. Another key example is the Malawi Multi-Hazard Risk Assessment , which emphasises safeguarding educational infrastructure from various hazards, including floods, droughts, earthquakes, and strong winds. By analysing the vulnerability of schools to multiple hazards and recommending seismic risk awareness campaigns, the project highlights how schools can be central to building disaster resilience and empowering youth in Malawi. Additionally, the recent GEM-EGU Summer School on GeoHazards Risk Assessment provided young scientists and professionals with hands-on training in risk assessment, ushering a new generation of disaster risk professionals equipped to contribute to global resilience efforts. Forecasting and Communicating Earthquake Hazard and Risk (FORCE) The ongoing project Forecasting and Communicating Earthquake Hazard and Risk (FORCE) is dedicated to improving earthquake risk modeling and communicating hazard information effectively to diverse audiences. By integrating cutting-edge risk assessment tools and promoting collaboration among local stakeholders, FORCE empowers communities to better understand seismic risks. The project’s focus includes creating earthquake hazard and risk models for smaller regions, where the capacity to assess risk may be limited. FORCE also emphasises knowledge transfer through training workshops, ensuring that local governments and communities are equipped with the tools needed for effective disaster risk reduction. One of the project’s core objectives is to enhance the ability of local communities to interpret and act on earthquake risk information. FORCE engages a wide range of stakeholders, including government agencies, disaster management professionals, and community leaders. While not directly targeting youth, FORCE’s training initiatives contribute to a more informed public, helping create a resilient future for all generations. Learn more here . Malawi Multi-Hazard Risk Assessment The Malawi Multi-Hazard Risk Assessment project provided critical insights into the country's vulnerability to various hazards, including floods, droughts, earthquakes, and strong winds. Key elements of the project involved exposure mapping and the definition of social vulnerability indicators, alongside the estimation of multi-risk indicators for various building types, such as schools, residential, industrial, government and healthcare facilities. The project thoroughly examined the vulnerability of schools, assessing infrastructure weaknesses that could disrupt education during disasters. Data provided by Malawi's Ministry of Education included details on primary and secondary schools. In the absence of local building typology data, the project used international benchmarks to estimate building and content values. A crucial aspect of the project was identifying 60 social vulnerability factors, 11 of which were related to education, with two focused specifically on schools: the lack of internet connectivity and school inaccessibility during the rainy season. These factors underscore the infrastructure deficiencies that can hinder education and emergency responses during disasters. Limited internet access affects the flow of critical information, while poor infrastructure can worsen during heavy rains, affecting school attendance. GEM’s seismic risk assessment also highlighted the importance of safeguarding educational infrastructure and recommended local-level seismic risk awareness campaigns. Schools can serve as vital hubs for building disaster resilience by educating communities about earthquake preparedness and ensuring a safer future for Malawi’s youth. Learn more here . Training and Communication for Earthquake Risk Assessment (TREQ) The Training and Communication for Earthquake Risk Assessment (TREQ) project aims to enhance public understanding of earthquake risks by focusing on capacity building and community-level awareness. The project trained disaster risk professionals and public communicators, enabling them to lead community workshops in cities like Cali, Quito, and Santiago. These efforts help raise seismic risk awareness and encourage local stakeholders to engage actively in disaster preparedness. TREQ also develops educational materials such as teacher guidelines, public-facing videos, and urban risk profiles for targeted cities. These resources play a crucial role in spreading seismic risk knowledge to the broader public, empowering communities, including youth, to mitigate disaster risks and take proactive steps toward resilience. Learn more here . GEM-EGU Summer School on GeoHazards Risk Assessment The GEM-EGU Summer School on GeoHazards Risk Assessment, held in September 2024, provided young scientists and professionals with advanced training in earthquake and geohazard risk assessment. Through interactive sessions and hands-on exercises, participants learned to use GEM’s tools, such as the OpenQuake engine, to assess earthquake risk and enhance resilience in their local communities. The program encouraged collaboration among participants from diverse backgrounds, facilitating knowledge exchange and the development of practical skills. Read the related article here . Preparing Future Generations for a Safer Tomorrow Through a diverse range of projects like the Malawi Multi-Hazard Risk Assessment, FORCE, TREQ, and the GEM-EGU Summer School, the Global Earthquake Model (GEM) Foundation is actively contributing to global disaster risk reduction efforts. By promoting resilience in communities and equipping stakeholders with the tools and knowledge needed to understand and mitigate earthquake risks, GEM plays a crucial role in preparing future generations to face the growing challenges of natural hazards. While GEM’s focus may not be specifically on youth, its initiatives align with the goals of IDDRR 2024 by ensuring that education and preparedness are at the forefront of building a more resilient future for all. ## No images found.

Country model to assess potential financial losses to commercial, industrial and residential buildings due to earthquakes Products China Financial Loss Model Country model to assess potential financial losses to commercial, industrial and residential buildings due to earthquakes Share Facebook LinkedIn Description The China financial loss model has been developed by GEM using public sources of information, such as past seismicity, and geodetic and geologic data for the hazard component, combined with exposure and vulnerability data. The hazard component incorporates both faults and area sources. Earthquake occurrence rates on active faults are based on a new tectonic block model derived from the joint inversion of geodetic and geologic data. The model provides estimates of financial risk to residential, commercial and industrial buildings using GEM’s vulnerability models appropriate to Chinese construction practice. GEM has also developed an exposure model that can be used to estimate total losses to the building stock in addition to portfolio losses. Further technical information can be found in the documentation. GEM extensively collaborated with its private and public partners to test and validate the model against industry standards in order to produce a new model that represents GEM’s view of risk. The model is available in Oasis LMF format. How to cite this work N.A.

News A Conference, an Earthquake and a Reminder of Why We Do This Work By: by Helen Crowley Jul 15, 2026 Jul 15, 2026 Share Facebook LinkedIn During the GEM Conference in Zagreb, two powerful earthquakes struck Venezuela in quick succession. As news emerged and the scale of the disaster became clearer, with thousands of lives lost and many more people injured or displaced, our conversations about earthquake hazard and risk assessment suddenly felt much less theoretical. Only afterwards did it occur to me how extraordinary the timing had been. The conference had brought together many of the scientists and practitioners behind the world's leading rapid earthquake impact systems, including ShakeMap , PAGER , GDACS and GEM , to discuss how earthquake impact information can be made faster, more reliable and more useful. Coincidentally, the conference also marked the release of GEM's new generation of global earthquake hazard and risk models, the result of several years of collaboration with partners around the world. Within hours, many of those same tools and models were being used to produce an initial picture of the earthquake's impacts. Through GEM's role in the ARISTOTLE consortium, we shared our rapid impact assessment for the Venezuela earthquakes with the European Union's Emergency Response Coordination Centre. It was an early estimate, not a substitute for information from those on the ground. But in the first hours after an earthquake, this type of analysis can help identify where the impacts are likely to be greatest, providing valuable situational awareness while more detailed information is still emerging. For me, it was a powerful reminder of why this work matters. Earthquake risk modelling can often sound highly technical. We talk about hazard curves, exposure databases, vulnerability functions, loss estimates and uncertainty. These are all essential, but behind them lie some very practical questions: where is the ground likely to shake or deform, how often might it happen, who and what is at risk, and how can that information help people make better decisions before and after earthquakes? Those questions are becoming more urgent because the world exposed to earthquakes is changing. Cities continue to grow. Infrastructure systems are becoming increasingly interconnected. Buildings, populations and economies are evolving. The consequences of earthquakes are no longer measured only by damaged buildings, they also affect transport networks, utilities, hospitals, livelihoods, supply chains and public finances. This means our models need to evolve as well. That idea was reflected throughout this year's conference and underpins GEM's latest global model release. The aim is not simply to update datasets, but to broaden our understanding of earthquake risk and provide information that is more relevant to the decisions governments, businesses, emergency managers and communities face before and after earthquakes. This includes expanding our understanding of topics such as infrastructure risk, future exposure and the environmental consequences of earthquakes. None of this can be achieved by a single organisation. One of GEM's greatest strengths is its ability to bring together researchers, governments, civil protection agencies, development banks, engineers, insurers and many others around shared tools, data and models. Earthquakes cross borders, and the science we use to understand them has to be collaborative too. Looking back, what stays with me most from the conference is not only the scientific advances that were presented, but how quickly they became relevant. Within hours of discussing new approaches to earthquake hazard and risk assessment, many of those same methods were being applied to help understand a real disaster unfolding thousands of kilometres away. It was a reminder that our work is never just about developing better models. It is about helping societies prepare before earthquakes happen and supporting better decisions when they do. Of course, better models will never prevent earthquakes from happening. But they can help countries identify where risk is highest, prioritise investment, strengthen infrastructure, prepare financially and respond with better information when disasters occur. That is the main message I took away from Zagreb. If we want to reduce future losses, we need to keep investing in the models, data and partnerships that turn scientific advances into better decisions. ## No images found.

News GEM and its partners complete GFDRR’s Challenge Funds Global Exposure Database for Multi-hazard Risk Analysis (GED4ALL) By: May 28, 2018 Share Facebook LinkedIn A consortium led by the GEM Foundation with partners ImageCat Inc. and the Humanitarian OpenStreetMap Team completed recently an open exposure database for multi-hazard risk assessment, as part of the Challenge Funds portfolio, managed by the GFDRR, and funded by the Department for International Development (DFID) of the United Kingdom. The main objective of Challenge Fund Global Exposure Database for Multi-hazard Risk Analysis is the development of an open exposure database, for the purposes of performing multi-hazard risk analyses. The database is capable of storing different assets (building stock, lifelines, crops, socio-economic data) across six natural hazards: earthquakes, floods, volcanoes, strong winds, tsunamis and drought. The database has been successfully piloted in Tanzania for the development of an exposure model at the national scale, and to the city of Dar Es Salaam demonstrating how an exposure dataset at a building-by-building resolution can be created. The process has also been demonstrated for five countries around Tanzania (Ethiopia, Uganda, Kenya, Malawi and Mozambique) as well as Cape Verde, Senegal, Mali, Niger and in other countries outside of the African continent. The outputs include a detailed description of the structure of the tables comprising the GED4ALL exposure database schema and the relationships between them, a description of the software components required for installation and basic operation of the database and the associated tools for converting, importing and exporting data. Paul Henshaw, GEM Director of Technology and Development also notes that “The project is a major step forward in defining a global multi-hazard database for use in assessing risks due to natural hazards. The approach also demonstrates how the combination of international expertise, open standards, local knowledge, inclusiveness and collaborative approach can encourage risk awareness and mitigation.” Paul also presented the final outputs of Global Facility for Disaster Recovery and Reduction (GFDRR) Challenge Fund 2: Global Exposure Database for Multi-hazard Risk Analysis (GED4ALL) during the projects closing workshop held in Dar Es Salaam, Tanzania from 22-24 March. The British Geological Survey (BGS) and University College London (UCL) presented the results of Challenge Fund 1 (multi-hazard database) and 3 (vulnerability database) respectively. More than 30 individuals participated from various organizations such as 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), GFDRR (USA), DFID UK, IDF (Switzerland), BGS (UK), UA (Netherlands), NGI (Norway), NOC (UK), CIMA (Italy) and UCL-EPI (UK).
