  • METIS | Global Earthquake Model Foundation

    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.

  • METEOR | Global Earthquake Model Foundation

    Projects METEOR Modelling Exposure Through Earth Observation Routines (METEOR) Versión en español English version Share Facebook LinkedIn Overview Outcomes Training Outreach Photos Publications Anchor 6 Background At present, there is a poor understanding of population exposure in some Official Development Assistance (ODA) countries, which causes major challenges when making Disaster Risk Management decisions. Modelling Exposure Through Earth Observation Routines (METEOR) takes a step-change in the application of Earth Observation exposure data by developing and delivering more accurate levels of population exposure to natural hazards. Providing new consistent data to governments, town planners and insurance providers will promote welfare and economic development in these countries and better enable them to respond to the hazards when they do occur. Objectives METEOR aims to formulate an innovative methodology of creating exposure data through the use of EO-based imagery to identify development patterns throughout a country. Stratified sampling technique harnessing traditional land use interpretation methods modified to characterise building patterns can be combined with EO and in-field building characteristics to capture the distribution of building types. These protocols and standards will be developed for broad application to ODA countries and will be tested and validated for both Nepal and Tanzania to assure they are fit-for-purpose. Objectives of the project look to: deliver exposure data for 47 of the least developed ODA countries, including Nepal and Tanzania; create hazard footprints for the specific countries; create open protocol; to develop critical exposure information from EO data; and capacity-building of local decision makers to apply data and assess hazard exposure.

  • CCARA | Global Earthquake Model Foundation

    Projects CCARA Caribbean and Central America Earthquake Risk Assessment (CCARA) Versión en español English version Share Facebook LinkedIn Overview Outcomes Training Outreach Photos Publications Anchor 6 Background Earthquake risk is on the rise and earthquakes are expected to take an increasing number of lives. Hazard and risk assessments are the foundation for raising awareness among policy makers and the general public, forming the basis for decisions and actions that effectively build resilience and can reduce risk. While important work has been carried out in the Central American and Caribbean region to understand earthquake risk assessment and management there is still ample room to enhance that understanding and properly introduce it in decision- and policy-making processes. In many areas of the world, state-of-the-art information and tools to assess earthquake risk have been inaccessible for a long time. As a first step to tackle this problem, the Global Earthquake Model (GEM) has been created and spent the past 11 years collaboratively advancing open source science and technology for global state-of-the-art seismic hazard and risk modeling, data collection, and risk assessment at scales from local to national, regional, and global. Objectives The project aims to calculate hazard and risk, and to estimate the compounding social and economic factors that increase the physical damage and decrease the post-event capacities of populations to respond to and recover from damaging earthquake events in The Caribbean and Central America, by involving local experts from throughout the region. The goal of the Program in Central America and the Caribbean is to develop capacity in the region for earthquake risk assessment by leveraging GEM tools and resources, to enhance the understanding of earthquake risk, and to bridge the gap between risk assessment and disaster risk reduction. To improve the understanding of earthquake risk in the Central America and Caribbean region while developing local capacities to use open source resources for producing earthquake hazard and risk information at regional, national and local scales. To engage with decision-makers and other end-users to make the connection between advanced risk assessment by local experts and risk-reducing action and so influence DRR policy.

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. Download Files Anchor 1 Anchor 5 Improving global capacity for seismic hazard and risk This part of the program was designed to improve the understanding and awareness of earthquake hazard and risk, and to help bridge the gap between the information produced in detailed hazard and risk assessment studies and its communication to a wide variety of stakeholders (which range from local experts with the remit to assess seismic risk to decision-makers responsible for the implementation of risk reduction measures). a. Website for OpenQuake online training The OpenQuake online training was designed for different types of audiences with diverse backgrounds and expertise. Through this platform, participants interact with GEM scientific and technical teams to learn the main concepts of earthquake risk assessment, along with the basic features of the engine. [English ] b. Onsite Training Workshop One-day workshop designed to improve the understanding and awareness of earthquake hazard and risk and to help bridge the gap between the information produced in the project and its communication to a wide variety of stakeholders. The session allowed participants to explore and prepare the required input files for earthquake scenarios in the OpenQuake engine. OQ Engine Video Tutorials | English | Example Material Anchor 4 Communicating and raising earthquake risk awareness The activities in this component focused on raising the awareness of the public on earthquake hazard and risk by training a diverse group of disaster risk reduction (DRR) professionals together with personnel in charge of communicating risk to the public, and by conducting community-based workshops in selected areas of the pilot cities by those who were trained by the project. Speech by Domenico Scalpelli (WFP Representative) on the presentation of the Earthquake Risk Assessment Results The speech was delivered on March 6, 2024 at Six Season Hotel, Hall Room, Bunka, Bangladesh (10:00 am to 12:30 pm).

  • SARA Project | Global Earthquake Model Foundation

    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).
