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 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 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. 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 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.

Projects BEYOND BUTTON PUSHING Earthquake Risk Assessment and Sensitivity Analysis for California Versión en español English version Share Facebook LinkedIn Overview Report Anchor 6 Background The goal of the project was to show how important the quantification of uncertainty is in estimating and understanding California’s earthquake risk using OpenQuake - GEM Foundation’s state-of-the-art open source earthquake hazard and risk assessment software. With OpenQuake’s plug-and-play capabilities, expert users can individually select or substitute every model component, data, and assumption. This feature will help model users and decision makers to: 1) ‘ask the right questions’ when evaluating model results; 2) better interpret risk assessment results and gain trust in model results; and 3) make better risk management decisions. Duration: 2015-2017 Objectives The main objectives of this project are to: Establish representative sets of exposure: ‣ for the San Francisco Bay Area; ‣ for the Southern California region affected by the Shakeout Scenario Choose specific results (risk metrics) to use as a basis for comparison. Produce ‘baseline’ results from OpenQuake, using a ‘control’ set of assumptions. Undertake a thorough sensitivity analysis for the risk estimates for California based on the UCERF3 model by running OpenQuake multiple times, each time varying one assumption or parameter, such as: ‣ earthquake probabilities (controlled by assumptions about fault geometries, slip rates, maximum magnitudes); ‣ ground motion model selection; ‣ vulnerability functions; ‣ site conditions; and ‣ statistical treatment of uncertainty and correlation Beyond the aims stated at the outset of the project as listed above, several additional objectives were achieved during the course of the project, including the following: Implement within OpenQuake the latest seismic hazard model for California based on the recently published Uniform California Earthquake Rupture Forecast version 3 (UCERF3), produced by the U.S. Geological Survey and the Working Group on California Earthquake Probabilities. Calculate the average annual loss estimates for all 8,057 census tracts in California, using the seismic hazard model based on UCERF3. Establish the range (distribution) of scientifically viable results for the chosen risk metrics by accounting for the various uncertainties in the hazard model. Identify the components of the hazard model contributing most to the overall uncertainty in the risk metrics for the different exposure portfolios. Implement a model simplification (‘logic-tree trimming’) software tool to reduce the number of computer runs and greatly speed up the time required for running the risk model for California.

Projects SIGMA3 SeismIc hazard and Ground Motion Assessment Versión en español English version Share Facebook LinkedIn Overview Work Packages Training Dissemination Photos Publications Anchor 6 Overview SIGMA3 is a research and development (R&D) program on SeIsmic hazard and Ground Motion Assessment. It is the 3rd part of a larger R&D initiative initiated in 2011 to support innovation in the field of probabilistic hazard assessment (PSHA). SIGMA3 is fully funded by the industry at 100%. The program grounds its roots in methodological developments, as well as in the identified shortcomings of the two preceding editions, labelled SIGMA and SIGMA2. The previous two programs have led to insightful datasets and models to accompany the inception of probabilistic site-specific PSHA studies in low-to-moderate seismicity areas, such as France, for instance. However, nowadays, additional progress is still needed to reduce epistemic uncertainties and improve confidence in probabilistic seismic hazard studies. To this end, SIGMA3 gathers a group of researchers and engineers actively involved in the seismic hazard community and recognized for their expertise. More details about the project are available here: https://sigma-programs.com/ Objectives The SIGMA program is a Research and Development project about seismic hazard and ground motion. It has the objective to improve data and develop methods necessary to best estimate SHA by producing Hazard levels more adapted to the site. Improve available practices for safety demonstration to get consensus with the largest international community for R&D and industrial applications Improve confidence and accountability in seismic hazard assessments by quantifying and propagating uncertainties on Seismic Source and Ground Motion Characterization Strengthen the link between seismologists and engineers, and share feedback among consortium members Collaborators Steering Committee The Steering Committee handles strategic and technical decision-making in the SIGMA3 program and provides recommendations on the program’s orientation, informed by the Scientific Committee’s expertise.

Projects METIS Methods and Tools Innovation for Seismic Risk Assessment Versión en español English version Share Facebook LinkedIn Overview Outcomes Training Outreach Photos Publications Anchor 6 Background GEM is set to start a 3-year project called METIS or Methods and Tools Innovation for Seismic Risk Assessment funded by the European Commission. The project is part of the Safety margins determination for design basis-exceeding external hazards program. Electricite De France (EDF), a GEM technical collaborator, is coordinating the project which will be implemented in collaboration with 14 other organizations. GEM will contribute to the task on seismic hazard assessment and on PSA Tools and Methodology. In the hazard task, GEM will implement into the OQ Engine methods such as vector-valued probabilistic seismic hazard analysis (PSHA), cluster-based PSHA as well as new methods to propagate epistemic uncertainties. Research will also be carried out in the context of processing earthquake catalogues to remove aftershocks and foreshocks and on testing PSHA models. GEM’s contribution to the PSA Tools and Methodology will concentrate on testing risk results. Duration: 2020 - 2025 More details: https://metis-h2020.eu/ Objectives The objective of METIS is to translate research into practice through rigorous and efficient methodologies and tools to assess seismic safety of NPP (nuclear power plants). It also aims to innovate current practice by combining simulation with experimental data. The research will develop methods to improve the ability to define safety limits for extremely rare events, which go beyond current design analyses (i.e. design extension for earthquakes). The refined seismic PSA (probabilistic safety assessment) is expected to provide meaningful support in defining regulations for safe design of NPP, as well as for assessing plant safety in real-time in case of temporary unavailability of relevant safety equipment or structures.
