Projects TREAD daTa and pRocesses in sEismic hAzarD Versión en español English version Share Facebook LinkedIn Overview Anchor 6 Background GEM is one of the partners of the Marie Skłodowska-Curie Actions (MSCA) funded TREAD project, which involves a consortium of 14 academic institutions and 8 private partners of the highest scientific level from 7 European countries. TREAD will train a new generation of seismic hazard scientists to tackle the challenges of earthquake forecasting in complex tectonic contexts such as the Europe and Mediterranean regions. During the 4 year project GEM will host and supervise two PhD students, one working with the hazard team and the other with the risk team, on the following topics: 1. Modelling distributed seismicity under innovative approaches (under joint supervision with the University of Milano, Bicocca, 2. Assessment of the impact of advanced seismic hazard modelling approaches on earthquake risk (under joint supervision with the University of Chieti-Pescara) More information at https://tread-horizon.eu/ . Duration: 2023-2027 Objectives The aim of TREAD is to train a new generation of seismic hazard scientists to tackle the challenges of earthquake forecasting in complex tectonic contexts such as the Europe and Mediterranean regions. A change of paradigm in seismic hazard is necessary to be able to fully account for the specific properties of earthquake source and seismic modes in those areas. For example, to calculate the probability of having multiple earthquake ruptures, the interaction between active faults across various space-time scales needs to be accounted for, as well as the effects of stress transfer and fault-fluid interaction in earthquake triggering. TREAD objectives are: 1) Developing a novel integrative approach to seismic hazard analysis in Europe and the Mediterranean by bridging the gap from small-scale laboratory experiments to large-scale observations. 2) Establishing physics-based earthquake modelling by linking computational modelling of earthquakes from millions of years to fractions of a second. 3) Transferring earthquake geology and computational modelling to hazard and risk assessment adapted to the needs of government, industry and scientific stakeholders.

Projects BANGLADESH Earthquake Vulnerability and Systemic Risk Assessment in Bangladesh Versión en español English version Share Facebook LinkedIn Overview Outcomes Training Outreach Photos Publications Anchor 6 Background This project follows a specific support request made by the Ministry of Disaster Management and Relief (MoDMR) to the UN Office for Disaster Risk Reduction (UNDRR) and the UN Resident Coordinator’s Office (UNRCO) for a sub-national earthquake hazard and risk assessment in Bangladesh. The GEM Foundation has the role of technical expert lead of the project which will include the following activities: Needs and Gaps Assessment Technical Panel Formation and Initial Consultations Seismic Hazard Mapping Exposure Mapping Seismic Vulnerability Assessment Seismic Risk Mapping and Interpretation Stakeholder Consultation and Validation Preliminary Model Dissemination and Training Workshop Funding and technical partner: UNDRR Duration: 2023 - 2024 Objectives The main objective of this project is to develop a detailed, open, sub-national earthquake risk model and evaluate seismic risk for Bangladesh at the zila and upazila levels. The complete risk model will comprise a probabilistic seismic hazard model, a building exposure model, and a seismic fragility and vulnerability model for the building stock of Bangladesh. Additionally, it includes critical scenarios for key cities, identified based on the results of the probabilistic risk assessment and in consultation with local stakeholders and experts, in a panel led by the Ministry of Disaster Management and Relief (MoDMR), and including representatives from the Ministry of Housing and Public Works, Bangladesh Bureau of Statistics, Geological Survey of Bangladesh, Bangladesh University of Engineering and Technology, and University of Dhaka.` Collaborators In collaboration with the GEM Foundation, the Technical Panel steering this seismic risk assessment initiative is a collaborative assembly of key stakeholders and experts. Led by the Additional Secretary of Bangladesh's Ministry of Disaster Management and Relief (MoDMR), it comprises representatives from vital entities, including the Department Of Disaster Management (DDM), the Fire Service and Civil Defence of Bangladesh, the Ministry of Housing & Public Works (MoHPW), and the Statistics and Informatics Division (SID) of the Bangladesh Bureau of Statistics (BBS). In addition, the panel includes the participation of seasoned national experts specializing in seismic hazard and risk assessment from institutions such as the University of Dhaka (DU), Bangladesh University of Engineering and Technology (BUET), and Jahangirnagar University (JU). Further enriching the panel's knowledge base are contributions from the Geological Survey of Bangladesh, the Centre for Urban Studies (CUS), and the United Nations Development Programme (UNDP), Bangladesh.) Location Bangladesh Earthquake Hazard and Risk Assessment Results This section summarises the various assessments conducted to understand the potential impact of earthquakes in Bangladesh. These assessments cover a range of factors, including the likelihood and severity of ground shaking, liquefaction potential, exposure of people and buildings, vulnerability of infrastructure, and the overall seismic risk posed to the country. The following list details the outputs generated from each assessment. Bangladesh Profiles | Past Earthquakes **ALL RESULTS ARE PRELIMINARY AND UNDER REVIEW** a. Population and Building Exposure Exposure models play a critical role in seismic risk assessment by quantifying the potential exposure of buildings and infrastructure to earthquake hazards. These models are structured databases that catalogue the characteristics of buildings within a specific geographic area, including their location, construction material, age, occupancy type, and structural design. The depth and accuracy of this data directly influence the effectiveness of the seismic risk evaluations, as they allow for a detailed understanding of how different structures are likely to perform during an earthquake. Download Files b. Infrastructure Exposure In addition to residential, industrial, and commercial structures that were previously covered by GEM’s exposure models at the zila level (which have been updated to the upazila level during this project), we have also developed exposure models for the healthcare and educational facilities at the country, including all hospitals and clinics, and all schools, colleges, and universities. Map | Profile c. Earthquake Scenarios The project also constructed the rupture geometries for these events, selected a range of ground motion models, and assessed the potential impact—both in terms of damage and losses—that each event could inflict on the country if it were to occur today. The full scenario set consists of twelve events: seven historical events from 1664-1918, chosen out of many in this period, supplemented by five hypothetical events. Download Files d. Probabilistic Seismic Hazard Assessment The seismic hazard modelling and mapping section describes the approach taken to assess the seismic hazard in Bangladesh with the goal of creating a comprehensive seismic hazard model for Bangladesh that can be used for risk assessment and mitigation. The project started with a probabilistic seismic hazard model for the Indian subcontinent, which was updated and implemented for the OpenQuake engine. The model includes seismogenic source models, ground motion models, and considers various tectonic regions. This section also mentions the review of the seismic source model for northeast India and the improvements made to the model. Download Files e. Liquefaction Hazard Assessment The section "Liquefaction susceptibility and hazard assessment" discusses the inclusion of regional liquefaction occurrence models in the project, which predict ground failure using existing mapped information and above-ground inferences of below-ground conditions. These models were used for the national scale liquefaction hazard assessment in the second phase of the project identifying the factors that contribute to liquefaction, the methods used for assessment, and the potential damage and losses that can result from liquefaction. Download Files f. Seismic Risk Assessment The project estimated seismic risk metrics utilising the OpenQuake-engine's stochastic event-based risk assessment calculator. A probabilistic seismic hazard analysis model was employed to generate earthquake rupture forecasts, forming a stochastic event set over a 100,000-year span. Economic and human losses were computed for each event, producing event loss tables and year loss tables. Risk metrics included exceedance probability curves and average annualized losses. Fatality and injury estimates relied on vulnerability models informed by global earthquake data, with a focus on South Asian building characteristics. Results were tabulated nationally and regionally by the project. The assessment also considers the exposure and risk of healthcare facilities, educational facilities, and the national road network to seismic hazards.

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). Anchor 1 Anchor 5 Capacity development and institutional strengthening To promote sustainability, SARA’s work included the following: capacity development and institutional strengthening, and stakeholder engagement.

Projects ARISTOTLE Multi-Hazard Expert Advice System for ERCC Versión en español English version Share Facebook LinkedIn Overview Anchor 6 Background The All Risk Integrated System TOwards Trans-boundary hoListic Early-warning or ARISTOTLE consortium combines a number of services that enable a rapid understanding of events from various natural hazards (earthquakes and tsunami, volcanoes, severe weather and floods) and how they might unfold, thus aiding a deeper interpretation of the resulting hazards and impact. The GEM Foundation is supporting the consortium by providing an assessment of the impact of earthquakes using GEM's global exposure and vulnerability models, with a focus on metrics such as collapsed buildings and displaced people, such that it may provide an added value to existing rapid loss assessment services such as the USGS's Prompt Assessment of Global Earthquakes for Response (PAGER). Visit http://pilot.aristotle.ingv.it/ for more details about the project. Duration: 2022 - 2028 Objectives ARISTOTLE aims to provide Multi-Hazard Advice to the European Research Coordination Centre, either in advance of / during the activation of the EC Civil Protection Mechanism (CPM), in order to increase preparedness and response levels of the EU and to improve the ERCC’s assessment capacity. Collaborators ARISTOTLE is a multi-disciplinary partnership consisting of world-leading scientific centres in the areas of Earth and Climate sciences, providing operational and monitoring services, early warning and information systems as well as contributing to innovation and research actions.

Projects PAPERS Piattaforma Analisi Pericolosità E Rischio Sismico Versión en español English version Share Facebook LinkedIn Overview Anchor 6 Background The Global Earthquake Model (GEM) Foundation has launched the PAPERS project (Piattaforma Analisi Pericolosità E Rischio Sismico), an initiative aimed at developing a new WebGIS platform for scenario hazard and risk assessment in Italy. The project has been funded as one of the cascade grants launched by the High-Performance Computing, Big Data e Quantum Computing Research Centre, one of the five National Centres established by the Italian National Recovery and Resilience Plan (NRRP), under Spoke 5 - Environment and Natural Disasters . The first training workshop of the project related to the use of the OpenQuake engine was successfully conducted online on April 1st, 2025, marking the first in a series of planned training events. This first workshop also served for exploring potential third-party contributions to models that could be integrated into the platform. Objectives PAPERS will enhance seismic risk assessment in Italy through advanced computational techniques and open-source models and tools. The project is organised into three modules, each focusing on a critical objective. The first module involves building the operational platform, leveraging the OpenQuake (OQ) Engine. The integration of High-Performance Computing (HPC) will facilitate complex analyses, while interoperability with external software will streamline data management. The second module focuses on updating Italy’s national exposure models. This involves compiling databases of buildings, critical infrastructure, and distributed networks at different geographic scales in the country. The project will integrate existing models with newly available datasets. This effort will provide a more comprehensive understanding of the seismic vulnerability of the Italian-built environment. As part of the third module, the platform will feature preloaded models of seismic hazard, exposure, and vulnerability, along with a range of earthquake scenarios, including historical earthquakes and events from a stochastic catalog based on the 2020 European Seismic Hazard Model (ESHM20). Alternative risk mitigation strategies will also be explored through dedicated multi-criteria decision-making approaches. Collaborators Project Coordination: Fondazione GEM (Global Earthquake Model Foundation) Main Collaborating Institution: Università degli Studi di Bari Aldo Moro Funding Agency: The project is funded under the Italian National Recovery and Resilience Plan (PNRR), Mission 4, "Education and Research" - Component 2, "From Research to Business" - Investment Line 1.4, supported by NextGenerationEU. Locations Pilot Site for Seismic Risk Analysis: An Italian city to be determined during the project, intended as a demonstration case for urban-scale seismic risk analysis. Testing Locations: The project will involve data collection and analysis on a national scale across Italy. Anchor 1 Anchor 5 Anchor 4 Anchor3 Publications

Projects NEAM-COMMITMENT North-Eastern Atlantic and Mediterranean Tsunami Risk Management and Planning Versión en español English version Share Facebook LinkedIn Overview Anchor 6 Background NEAM-COMMITMENT aims to improve tsunami risk management and planning in the NEAM region. It endeavors to contribute primarily to two key components of tsunami risk governance: capacity building through tsunami hazard assessment and mapping at the national scale, and improved tsunami evacuation planning at the local level through a novel multi-hazard approach. Guidelines will be drafted for the methodologies applied to develop the national tsunami inundation and local tsunami evacuation maps to contribute to improved tsunami risk management planning. Duration: 2025 - 2027 More details: https://civil-protection-knowledge-network.europa.eu/projects/neam-commitment#inpage-section-description Objectives The project has two objectives: to develop national tsunami inundation maps in Cyprus, Greece and Spain through the methodology applied to produce tsunami inundation maps for evacuation planning in Italy, aiming to achieve compatible tsunami inundation maps across the NEAM region; to address the need for a multi-hazard approach for effective tsunami evacuation management to complement existing tsunami evacuation management guidelines. The proposed new approach focuses on multi-hazard cascading effects concerning tsunami evacuation and emergency management and will be piloted in local sites in Greece and Italy.
