News Inaugural meeting of the EFEHR consortium: 2020 European Seismic Hazard and Risk Models: Current Status and Next Steps towards the Final Release By: Sep 21, 2020 Share Facebook LinkedIn EFEHR webinar participants GEM participated in the inaugural meeting of the EFEHR consortium held virtually on September 10, 2020. The inaugural meeting deliberated the current status and next steps toward the final release of the 2020 European Seismic Hazard and Risk Models. Several other GEM scientists who have been supporting the development of the risk model also participated. “As an Observer member of the consortium and as a global institution, GEM is able to support the mission of EFEHR by providing the OpenQuake Engine and accompanying databases and libraries, and by providing technical assistance in developing advanced hazard and risk models for Europe. GEM’s role is also as an interface between the European scientific community and public and private organizations worldwide that have an interest in earthquake hazard and risk models and the earthquake hazard/risk research community in Europe.” John Schneider, GEM Secretary General. GEM has provided expert input into the new Seismic Risk Model for Europe, and the analysis software developed and maintained by GEM – OpenQuake – has been a cornerstone for this regional work. The Consortium is expected to help bring European organizations together to coordinate earthquake hazard and risk research and its applications. The GFZ in partnership with ETH has worked together in bringing this collaboration into fruition. The Consortium also benefits from the involvement of a number of organizations that, in addition to GEM, play an observer role in the General Assembly: these currently include the European Association for Earthquake Engineering (EAEE), European-Mediterranean Seismological Centre (EMSC), Observatories and Research Facilities for European Seismology (ORFEUS), and European Seismological Commission (ESC). European Facilities for Earthquake Hazard and Risk or EFEHR is a non-profit network of organizations and community resources aimed at advancing earthquake hazard and risk assessment in the European-Mediterranean area. EFEHR supports local and national efforts in one of the three service domains in the Thematic Core Service (TCS) Seismology within the European Plate Observatory System (EPOS). The two others are ORFEUS (waveform services) and CSEM-EMSC (seismological products services). Visit for more information. No images found. GALLERY 1/0 Gallery VIDEO RELATED CONTENTS

Back to Bangladesh Outcomes Bangladesh 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.

News GEM News Briefs: Jan-Mar 2023 By: Apr 11, 2023 Share Facebook LinkedIn During this period, GEM scientists have also participated in various international virtual conferences and events on loss models, earthquake risk assessment, and global challenges in earthquake risk and catastrophe modelling. Here's a round-up of GEM's other notable activities over the past three months. GEM celebrates 14th year anniversary On March 9th, 2009, the Global Earthquake Model (GEM) Foundation was incorporated in Pavia, Italy as a non-profit organization, giving the Foundation a legal identity with a vision of a world that is resilient to #earthquakes (and other natural hazards). Over the past three years (from April 16, 2020 to April 17, 2023), public and private risk professionals, researchers and managers have downloaded a variety of free resources 8,427 times from the GEM website to better understand and mitigate earthquake risk. The list is topped by the Global Seismic Hazard map v2018.1 (1,124), the OpenQuake Engine (1,002) and the Global Seismic Risk map (492). Since GEM started tracking the downloads in 2019, visitors have downloaded various resources for a total of 12.6K. In celebration of GEM@14, here are the other most popular resources from our website and we’d like to invite you to download them from our products and publications at https://globalquakemodel.org/products and https://globalquakemodel.org/publications . NERC renews GEM sponsorship The United Kingdom through the National Environmental Research Council (NERC) has signed a new agreement as GEM Public Sponsor. NERC will continue to support GEM through 2025. Within the new sponsorship agreement, GEM’s engagement with the COMET project will also continue. The renewed partnership also brings GEM, COMET, the UK science community, as well as all those vulnerable to earthquakes globally to work together to achieve a common vision: earthquake resilience through the advancement of earthquake science. Towards New Frontiers of Earthquake Model Development – How collaboration helps manage earthquake risk across the world (Catrisk management and modelling summit held in London from March 7-9, 2023) Recently, GEM participated in the 10th Annual Cat Risk Management and Modelling Summit held in London. John Schneider of GEM and Goran Trendafiloski of Aon Impact Forecasting led the interactive roundtable discussion: Towards New Frontiers of Earthquake Model Development – How collaboration helps manage earthquake risk across the world. The discussion highlighted the collaboration between GEM, Aon Impact Forecasting and NRCan in developing a new model that combines the latest seismic hazard model for Canada, implemented by NRCan natively in GEM’s OpenQuake engine, with Impact Forecasting’s enhancements for secondary perils, including liquefaction, landslides, tsunami and fire following earthquake. Furthermore, the discussion also focused on the importance of building partnerships between public and private organizations to collaborate on the reduction of disaster risk worldwide. John and Andres Abarca, GEM Product Developer, also met current and prospective collaborators at the event and discussed GEM’s available earthquake data sets and risk models. NIED workshop on Japan earthquake hazard in Tohoku Marco Pagani and John Schneider (virtually) participated in the National Research Institute for Earth Science and Disaster Resilience (NIED) workshop on Japan earthquake hazard in Tohoku on February 10th, 2023 held in Tokyo, Japan. John presented an overview of GEM, its scientific and operational framework, earthquake models, databases and tools, and future programs. Marco presented GEM’s current efforts to update GEMs earthquake hazard mosaic of models, with a particular focus on GEM’s collaboration with NIED.. Following the workshop, John and Paul Henshaw, GEM Director of Technology and Development met a contingent from NIED in Pavia, Italy in March led by Hayashi Haruo who served as NIED President from April 2016 to March 2023. Hayashi-san expressed confidence in NIED’s commitment to continuing its work with GEM as part of the strengthening international collaboration and shift toward multi-hazard risk assessment research. NIED recently submitted a 5-year proposal to the Japan Ministry of Education, Culture, Sports, Science and Technology (MEXT) for the renewal of its science program, including sponsorship of GEM. A presentation on NIED and GEM partnership by Dr. Hiroyuki Fujiwara, Director-General of Research Center for Reinforcement of Resilient Function at the Tohoku hazard workshop. GEM and Swiss Re collaboration to build a Global EarthquakE ScEnario database or GEESE The project supported by SwissRe aims at building a database containing the information required to perform a scenario hazard and risk analysis for every earthquake included in the ISC-GEM catalog (the acronym used for this database is GEESE which stands for Global EarthquakE ScEnario). This semester we started compiling the information and the tools required to build the database. This includes tools for automatically retrieving information from the USGS Shakemap database and for uploading this information into a dedicated database. GEM Earthquake Consequences Database The GEM Risk team developed an Earthquake Consequences Database, which contains a wealth of information on several recent earthquakes, both in terms of the geophysical descriptions of the earthquake and its effects on the human environment. The GEM Hazard team created tools for this purpose to parse and display ruptures suitable for modeling in OpenQuake from data created by external sources (such as the USGS). The database will be launched in June. Asian Development Bank – Mongolia project As part of a project with Willis Towers Watson (WTW) on “Strengthening Capacity on Disaster Risk Assessment, Reduction, and Transfer Instruments in Mongolia”, funded by the Asian Development Bank (ADB), the Risk Team significantly improved the exposure model for Mongolia. The residential exposure is now based on the latest population and housing census of Mongolia, undertaken in 2020. The housing census provides information about the different types of housing, wall and roofing materials, the age profile of the housing stock and its current condition. The primary data source for modelling the commercial and industrial exposure was the 2016 establishment census of Mongolia, supplemented by updated establishment counts for the year 2020 per economic activity type, by region, aimag (provinces), soum (secondary subdivision) and the capital city of Ulaanbaatar. Global Resilience Index Initiative (GRII) Within the framework of the Global Resilience Index Initiative (GRII), GEM developed global maps of populations exposed to earthquakes and coastal/riverine floods. These maps have been integrated into the Global Systemic Risk Assessment Tool (G-SRAT), which is the data and analytics portal for the GRII, and launched at the COP-27 conference last November. You can access G-SRAT portal and the various datasets here: https://global.infrastructureresilience.org/ Global vulnerability database GEM created a dedicated website to host the documentation for the global vulnerability model. The documentation is accessible through the URL https://docs.openquake.org/vulnerability and is currently subdivided into six main chapters covering the multiple stages of vulnerability modelling. With this development, the plan is to improve the transparency of this component and ensure our partners comprehend how the vulnerability functions were developed. No images found.

Publications Estimating Road Disruptions in Urban Contexts Due to Earthquakes Using Machine Learning Surrogates Share Facebook LinkedIn Download 2025 | Peer-reviewed The estimation of road disruptions due to building debris in urban contexts requires the availability of exposure data at the building level, which is often not available. In this study, we explore how open global datasets at different scales can be integrated with machine learning algorithms to estimate road disruptions following seismic events, overcoming the need for detailed datasets. Using simulated impact data for the municipality of Lisbon, we train a Random Forest model to predict road disruptions due to building collapses. Then, we apply this model to another urban environment (the municipality of Amadora) to evaluate the performance of the model using input data unseen during the training process. Finally, we employ the surrogate model using information extracted from globally available datasets characterizing the built environment and the road network. The proposed approach allows identifying areas within urban centers where road disruptions are likely to occur, and where risk reduction measures should be prioritized to minimize the impact of destructive earthquakes.

GEM Impact Story Series Fascinación por los rompecabezas y los números a una edad temprana Desde muy joven, me cautivaron los acertijos y los números. Pasaba horas armando acertijos, sin saberlo, perfeccionando el enfoque y la paciencia. Los números también me fascinaban, los veía como algo divertido e infinito. Incluso un simple ábaco se sentía emocionante. Mirando hacia atrás, estas primeras pasiones sentaron silenciosamente las bases para las habilidades en las que confío todos los días en mi vida profesional. Crecimiento y cambio: hermandad, memoria y forma del tiempo Andar en bicicleta con mi hermano mayor fue nuestra aventura de la infancia: escalar colinas, reunirnos con amigos y ver cómo cambia el cielo al atardecer. Esos momentos me enseñaron a notar el paso del tiempo, un sentimiento de asombro que aún persiste. Compartimos todo, con solo 1.5548 años de diferencia, un número que calculé con orgullo cuando era niño. Nuestro vínculo nos dio una mezcla de sensibilidad y resiliencia, moldeada por crecer en un mundo anterior y durante el auge tecnológico. Mirar hacia atrás me ayuda a mantenerme conectado con lo que siempre ha estado ahí, guiando silenciosamente en quién me he convertido. Epicentro de una vocación: el día en que los edificios cayeron y el miedo encontró una voz Tenía 13 años cuando la tierra me mostró su poder. El 13 de enero de 2001, se produjo un terremoto de magnitud 7,7 mientras estaba en un edificio de cuatro pisos con mi hermano. El temblor se sintió interminable. Aprendí que los edificios pueden caerse y que el miedo tiene un sonido: gritos, paredes agrietadas y un corazón palpitante. Siguieron réplicas, junto con daños a nuestra casa. Pero lo peor fue el deslizamiento de tierra que se cobró amigos y familiares. Ese día dejó una cicatriz duradera y, sin saberlo, se convirtió en el punto de partida de todo lo que me moldearía. Entre vigas y planos: descubriendo un deber de protección Mis padres, un arquitecto y un ingeniero civil, me enseñaron que la ingeniería es más que un trabajo; es servicio y esperanza. Visitando sitios de construcción cuando era niño, encontré mi vocación. Seguí Ingeniería Civil, atraído por las ecuaciones y la resolución de problemas. Pero incluso entonces, sentí que tenía que significar más que exámenes: tenía que proteger vidas. Comencé a ver que un buen diseño no es solo técnico; es una herramienta para la resiliencia y la seguridad. De las líneas de falla a la primera línea: el trabajo en equipo y el poder silencioso del liderazgo En 2010, me uní al Ministerio de Medio Ambiente, donde me di cuenta de que comprender el riesgo era solo el comienzo: había que comunicarlo, monitorearlo y actuar en consecuencia. Comencé como técnico de monitoreo sísmico y geológico, trabajando turnos largos con equipos limitados pero con una gran determinación. Automatizé procesos, construí herramientas y me acerqué constantemente a mi objetivo: proteger a las personas a través de acciones significativas e informadas por datos. Mientras trabajaba a tiempo completo, obtuve un MBA para comprender mejor cómo administrar, planificar y liderar. Fue un desafío, hacer malabarismos con las clases nocturnas y monitorear los turnos, pero me enseñó disciplina, trabajo en equipo y liderazgo. El modelo de Liderazgo Situacional de Blanchard todavía me guía hoy. Una puerta en una pared: descubriendo GEM y Openquake En 2014, descubrí GEM y sus herramientas OpenQuake: hizo que la ciencia se sintiera clara y accesible. Probé los datos de El Salvador y me uní a una comunidad global a través de foros. En 2017, mientras estudiaba en Japón, utilicé GEM para mi tesis sobre la vulnerabilidad sísmica de los edificios escolares. Ese momento lo cambió todo: me di cuenta de que la ciencia, el contexto local y el propósito humano podían trabajar juntos para reducir el riesgo y desarrollar resiliencia. Herramientas abiertas, objetivos compartidos: Fortalecimiento de la evaluación de riesgos a través de las fronteras IEn 2019, regresé a El Salvador y propuse usar OpenQuake y datos locales para actualizar modelos de peligro obsoletos. Compartí mis conocimientos, y pronto estos métodos se utilizaron en proyectos del Banco Mundial y el BID. Aunque estaba en el extranjero durante el proyecto CCARA, contribuí con clasificaciones esenciales de movimiento fuerte. Más tarde, me invitaron a Costa Rica, prueba de que finalmente estaba tomando forma una visión regional compartida para el riesgo sísmico.n 2019, I returned to El Salvador and proposed using OpenQuake and local data to update outdated hazard models. I shared my knowledge, and soon these methods were used in World Bank and IDB projects. Though abroad during the CCARA project, I contributed essential strong-motion classifications. Later, I was invited to Costa Rica - proof that a shared regional vision for seismic risk was finally taking shape. El proyecto FORCE: un punto de inflexión en el riesgo y la política El proyecto FORCE marcó un punto de inflexión: construimos el primer modelo de riesgo sísmico nacional abierto de El Salvador. Por primera vez, incluimos proyecciones de riesgo futuro, vinculando el crecimiento urbano y las tendencias socioeconómicas. Fue revelador: la forma en que construimos hoy da forma al riesgo del mañana. Esta herramienta ayudó a influir en la política, respaldar nuestro nuevo código sísmico y mostrar que la reducción de riesgos no es solo técnica, es política, económica y profundamente humana. Un faro en el caos: el panel interactivo de riesgo sísmico Un hito importante fue la creación de un tablero interactivo de riesgo sísmico para estimar las pérdidas y guiar la respuesta de emergencia, esencial en un país donde cada minuto importa. FORCE también actualizó nuestro modelo de exposición y fomentó la colaboración. Creé una aplicación ArcGIS Survey utilizando la taxonomía de GEM, lo que permite a las instituciones recopilar datos. Estas herramientas prácticas y replicables son lo que necesitamos para una preparación y respuesta efectivas ante terremotos. A medida que la tierra se mueve, también debemos hacerlo nosotros He crecido, estudiado y viajado, pero sigo siendo ese niño que aprendió que la tierra se mueve y que debemos movernos con ella: sabiamente y con un propósito. Ahora, como padre, cada modelo, código o entrenamiento en el que trabajo tiene un significado más profundo. Algún día, espero que mi hija vea que la ciencia se trata de personas, y que la perseverancia y la bondad pueden dar forma a un mundo más seguro y esperanzador. Lo que recordamos, nos preparamos Finalmente, espero que esta historia sirva como un recordatorio de que vivimos en tierra sísmica y que la memoria debe permanecer viva. La preparación para terremotos no debe comenzar solo después de un desastre; debe entretejerse en nuestras decisiones diarias, en nuestros códigos de construcción y en la forma en que imaginamos el futuro. Si esta historia puede inspirar a otros profesionales, jóvenes o tomadores de decisiones a tomar medidas, entonces ya ha cumplido su propósito. Como dijo una vez Mahatma Gandhi: "De una manera suave, puedes sacudir el mundo" . ¡Grazie Mille! Acerca de las historias de impacto de GEM El riesgo sísmico sigue siendo abstracto y altamente técnico, y existen riesgos significativos de que, debido a una comprensión deficiente o limitada del mismo, los responsables de la formulación de políticas y el público en general no puedan aprovechar plenamente la información existente y futura que puede ayudar a crear mejores o mejorar las estrategias existentes de reducción y gestión del riesgo sísmico, especialmente a nivel local y nacional. Específicamente, el proyecto GEM Impact Stories tiene como objetivo: Recopilar y documentar historias en las que GEM o sus socios han contribuido a un cambio positivo; Alentar a los responsables políticos y de toma de decisiones a utilizar información basada en la ciencia y la evidencia para formular una estrategia de RRD sísmica a nivel nacional a través de historias positivas de cambio; y Aumentar la conciencia del público en general sobre el riesgo de terremotos y la preparación. Una sesión de preguntas y respuestas con Luis Ernesto Mixco Durán Luis Ernesto Mixco Durán obtuvo su título de Ingeniero Civil de la Universidad Centroamericana José Simeón Cañas (UCA) en El Salvador.

News GEM to start on new projects with The World Bank and UK Space Agency By: Jul 2, 2018 Share Facebook LinkedIn A lucky February at the GEM Foundation, which has been awarded two projects: 1) ‘Modelling Exposure Through Earth Observation Routines: EO-based Exposure, Nepal and Tanzania’ granted by the UK Space Agency; and 2) ‘Improving Post-Disaster Damage Data-Collection’ granted by The World Bank. UK Space Agency METEOR ProjectThe METEOR project not only involves GEM, but also the British Geological Survey (BGS), ImageCat, National Society for Earthquake Technology (NSET), The Disaster Management Department (DMD - Prime Minister's Office) of Tanzania, the Humanitarian OpenStreetMap Team (HOT) and Oxford Policy Management Limited (OPM). All of these institutions will join forces to develop and deliver more accurate levels of the exposure of populations and the built environment to natural hazards in developing countries. The first test countries will be Nepal and Tanzania, because of their differing exposure and hazard types, but one of the objectives of this project is to reach all 48 Least Developed ODA (Official Development Assistance) countries. Importantly, METEOR addresses Priority 1 of the Sendai Framework for DRR: “Understanding disaster risk:Disaster risk management should be based on an understanding of disaster risk in all its dimensions of vulnerability, capacity, exposure of persons and assets, hazard characteristics and the environment. Such knowledge can be used for risk assessment, prevention, mitigation, preparedness and response.” (Source: https://www.unisdr.org/we/coordinate/sendai-framework ) GEM and our partners will collaborate with local and national partners in order to ensure delivery of sustainable impact through capacity-building and knowledge-sharing throughout the project. Finally, METEOR will use Earth Observation (EO) data to develop and deliver products, the impacts of which will result in economic and social benefits. In fact, the outcome of this project will be to provide risk managers and disaster management authorities in developing countries with detailed, accurate and consistent data, and consequently to be better prepared to assess risk and to plan and prepare for, respond to and recover from natural hazard events. The World Bank-Improving Post-Disaster Damage Data Collection to Inform Decision Making ProjectOur second project comes as a response to an assignment launched by The World Bank entitled “Improving Post-Disaster Damage Data Collection to Inform Decision Making”. In order to be able to address this request, GEM, JBA Consulting, CIMA Foundation and Geocom Ltd. have formed a consortium. This combination of partners offers expertise in the four relevant natural hazards (earthquakes, landslides, floods, and cyclones), as well as decades of experience in the collection, aggregation and reporting of disaster damage data. The result of this project will be the design of a system that can support governments in damage assessment, data aggregation and reporting. The demonstrating country will be Armenia and the project will be divided into two phases: I - Assessing solutions and review of the situation in Armenia, and II - Conceptual design damage data collection system, with an adaptation to the Armenian context.

News GEM Foundation Strengthens Ties with the Global Tsunami Model Community By: Mar 22, 2024 Mar 20, 2024 Share Facebook LinkedIn Lisbon, March 20, 2024 - A two-day workshop held in Lisbon this week marks a significant step towards the formalisation of the Global Tsunami Model (GTM) initiative. Funded by a COST Innovators Grant , the GTM is transitioning from a self-convened group of scientists to a fully independent entity. Comprising a consortium of tsunami scientists from various global affiliations, the workshop hosted at the Faculty of Sciences, University of Lisbon, also gathered potential partners including the World Bank GFDRR, Munich Re, and the Global Earthquake Model (GEM) Foundation. Discussions focused on GTM's future governance structure, products, and services. Helen Crowley, GEM Secretary General was invited to share insights into the governance structure and funding mechanisms employed by GEM as well GEM's history, current status, and potential synergies with GTM. She highlighted the mutual benefits of collaboration, underscoring the shared interest in global tsunami hazard and risk modelling. Synergy with the GEM Foundation In addition to the products and services that the participants expect from an established GTM, such as global tsunami hazard and risk maps, profiles, and open-source software, collaboration could also extend to developing combined models that assess the impact of earthquake ground shaking and tsunami hazards simultaneously. Joint training programs and advocacy efforts promoting Early Warning Systems for both earthquakes and tsunamis were also identified as potential areas of collaboration. Avoiding Duplication of Efforts The workshop emphasised the importance of avoiding duplication of efforts with existing initiatives like GEM. Helen shared areas where collaboration could streamline development: Utilising GEM's ongoing work on a global stochastic event set (a collection of potential earthquake scenarios) and tailoring it to GTM's specific needs. Collaborating on improving the spatial resolution of global exposure models, ensuring they are suitable for tsunami risk assessment. Exploring ways to leverage and build upon the functionalities of GEM's open-source software, the OpenQuake Engine (OQ Engine). The GTM has been invited to share its progress in the next GEM Governing Board meeting in June and to make use of GEM’s presence in the WCEE2024 and UR24 events as opportunities for further networking with potential stakeholders. The Lisbon workshop signifies a crucial step towards a more robust and independent GTM. Collaboration with established initiatives like GEM holds the potential to significantly enhance the impact of both programs, ultimately leading to a better understanding and preparedness for earthquakes and tsunamis around the world.

Publications Assessing the impact of earthquake scenarios in transportation networks: the Portuguese mining factory case study Share Facebook LinkedIn Download 2017 | Peer-reviewed This study presents an open-source framework for the evaluation of the consequences of seismic events on transportation systems, and their impact on the surrounding industry. When applied to the specific case of a given company or organization, the framework allows the estimation of expected losses due to the disruption of specific transportation routes. The methodology was applied to a case study of a Portuguese mining factory whose production and exportation rely on the accessibility to strategic regions in the country using the highway and railway networks. Several methodological issues (e.g., spatial correlation in the ground motion, correlation in the damage) are explored within a sensitivity analysis to identify which features can impact seismic performance indicators (collapse and disruption probabilities; repair and disruption time) of specific routes.
