Publications Current Challenges and Future Trends in Analytical Fragility and Vulnerability Modeling Share Facebook LinkedIn Download 2019 | Peer-reviewed The lack of empirical data regarding earthquake damage or losses has propelled the development of dozens of analytical methodologies for the derivation of fragility and vulnerability functions. Each method will naturally have its strengths and weaknesses, which will consequently affect the associated risk estimates. With the purpose of sharing knowledge on vulnerability modeling, identifying shortcomings in the existing methods, and recommending improvements to the current practice, a group of vulnerability experts met in Pavia (Italy) in April 2017. Critical topics related to the selection of ground motion records, modeling of complex real structures through simplified approaches, propagation of aleatory and epistemic uncertainties, and validation of vulnerability results were discussed, and suggestions were proposed to improve the reliability and accuracy in vulnerability modeling.

FAQ of GEM Foundation Frequently Asked Questions Welcome to GEM's FAQ section, offering insights on sponsorship, participation, intellectual property rights, licensing, and trademarks. This resource aims to address common queries and assist in better understanding GEM's operations and engagement opportunities. Explore our FAQs for clear guidance on various aspects of involvement with us. Share Facebook LinkedIn How to sponsor and participate 1. What kind of institution is GEM? The GEM Foundation (Italian registered name “Fondazione GEM”) is a non-profit foundation regulated by Italian law and based in Pavia (hosted by EUCENTRE). 2. How can my company or institution collaborate with GEM? The first and most complete option is to become a GEM sponsor (for more details, please see the following FAQ). If this is not possible for any reason, you can consider starting a specific project and then signing an institutional collaboration agreement. “Institutional” means that the object of the collaboration must fall within the institutional aims of the GEM Foundation, which are described in detail in art. 2 of the statute. Our legal team can provide you with an agreement template for institutional collaborations. 3. How can my company or institution become a sponsor of GEM? As provided in art. 3 of GEM Statute, to become a GEM sponsor you should submit your application to the GEM Governing Board, specifying the sponsorship category, the Sponsorship duration, and the name of the designated member of the Governing Board. Should the Governing Board accept the new sponsorship application, the candidate will have to sign a sponsorship agreement through which they commit to: respect the Statute and the GEM Foundation rules and regulations; disburse the annual contribution in support of the Foundation’s activities set by the Governing Board for the specific participant category to which they belong. Our legal team can provide you with a sponsorship agreement for your specific category. 4. Can GEM support my company or institution just as a consultant or a service provider? Yes, it is possible but is not our preferred approach. Italian law does not prohibit non-profit organizations from doing business as a commercial entity. However, this approach is less in line with our core values and mission. Commercial activities are also more expensive for GEM to carry out due to increased administrative overheads and taxes. For these reasons, GEM undertakes commercial activities only where doing so benefits the community as a whole. GEM reinvests any surplus revenue from commercial projects for use in institutional activities, with a focus on supporting the Global South. 5. Which categories of sponsors are available? The GEM Statute includes three macro-categories of sponsors: a. Governor: they are voting sponsors and need to pay a financial contribution … b. Advisor: they are non-voting sponsors and need to pay a financial contribution … c. Associates: they are non-voting sponsors and do not need to pay any financial contribution; they may nominate a delegate to attend Governing Board meetings (without voting right). How to use intellectual property rights and licensing 6. What are the main GEM Foundation intellectual products? As part of its institutional activities, the GEM Foundation produces software, datasets, hazard models, scientific and informative articles, research reports, slides presentation, infographics, maps and pictures. As is well known, these types of materials are protected by intellectual property rights and, except where otherwise specified, the GEM Foundation is the sole rights holder. 7. What is GEM's approach to product rights and licensing? The GEM Foundation adopts an open approach to the management of rights on its products and supports the spread of phenomena such as free software/open source software, open access, open data. With a few limited exceptions, all intellectual products by the GEM Foundation are released with open licenses, such as the Free Software Foundation licenses for software and the Creative Commons licenses for creative contents, datasets and models. Every file that is released on our websites is accompanied by the corresponding license. From time to time, please check the license applied. If in doubt, you can contact licensing@globalquakemodel.org . 8. How to use GEM intellectual products? What types of licenses can be applied? In order to perform analyses using the OpenQuake engine, one needs both the engine software and a model. In order to use a model one must respect both software and data licenses. a. Software, AGPL The software license used by GEM, the GNU AGPL, allows users to use the software for any purpose, including commercial purposes, without having to request a specific permission and without needing to become active supporters of our projects. The AGPL does restrict (re)distribution and integration of the software - in particular it is not permitted to link AGPL software with closed-source software systems, even if this linkage is performed via a network. Users are permitted to modify AGPL software, however, users must remember to release any derived/modified versions openly under the terms of the AGPL. In essence this means that GEM software must remain open and cannot be made into closed products without permission. b. Data and Models The Creative Commons licenses applied to our creative contents, datasets and models, allow users to freely use and modify (by making derivative works) our products and require that the authorship of GEM Foundation is always correctly attributed and in some cases impose some additional restrictions on use. GEM models and datasets are distributed with either the CC BY-SA license which allows commercial use or the CC BY-NC-SA license which prohibits commercial use. Both are Share-Alike licenses; this means that the product and any modified or derived products may only be (re)distributed under the terms of the same license. In essence this means that GEM models must remain open and cannot be made into closed products without permission. c. Other content (slides, images, articles) Some content is distributed under the terms of the CC BY-NC-ND license which prohibits both commercial use and the creation of derived products; this means that you are free to redistribute the content but you may not modify or make commercial use of the content.

News Seismic Science in Action: Helen Crowley's AEES Joyner Lecture and Geoscience Australia Visit By: Dec 17, 2024 Nov 21, 2024 Share Facebook LinkedIn Helen Crowley, Secretary General of the Global Earthquake Model (GEM) Foundation, recently visited Australia, delivering the prestigious Joyner Memorial Lecture at the 2024 Australian Earthquake Engineering Society (AEES) Conference in Adelaide and engaging with Geoscience Australia in Canberra. Her visit highlighted the ongoing collaborations and future opportunities to enhance seismic resilience across the region. At AEES 2024, Helen presented the Joyner Memorial Lecture, titled “Why Seismic Hazard Modelling Has Become a Risky Business” , addressing the evolving challenges and advancements in seismic hazard modelling. Her talk explored the implications of these developments on building design and resilience strategies. Other notable keynote speakers included Timothy Sullivan from the University of Canterbury, New Zealand and David Wald of the U.S. Geological Survey. The conference served as a hub for earthquake scientists and engineers from academia and industry, promoting discussions on a wide range of topics of relevance to earthquake resilience. Helen remarked, “The AEES provides an invaluable opportunity for the earthquake community in Australia and neighbouring countries to exchange knowledge and build connections that are essential for advancing earthquake science and public safety.” Before the conference, Helen visited Geoscience Australia (GA), a long-standing GEM public partner, to explore collaborative projects and share updates on mutual interests. Whilst there she met with a number of teams within GA’s Community Safety Branch, including Earthquake Hazard, Vulnerability and Risk Mitigation, and Natural Hazards and Impacts. Key topics of discussion included advances in seismic hazard modelling, multi-hazard risk assessment with the OpenQuake Engine, the ongoing RAMSEY project, and areas of future collaboration in seismic hazard and risk assessment, both nationally and internationally. “The collaboration between GEM and Geoscience Australia demonstrates how partnerships can translate science into actionable outcomes, particularly in a region like Australia where seismic activity, while infrequent, still poses significant risks,” Helen said. Helen’s visit underscored the shared commitment to improving earthquake preparedness and risk reduction strategies in Australia and beyond. As both GEM and Geoscience Australia explore further opportunities for collaboration, such as aftershock hazard assessments and rapid impact assessment, these initiatives are expected to contribute to a safer, more resilient future.

Publications Impact of population spatiotemporal patterns on earthquake human losses Share Facebook LinkedIn Download 2025 | Peer-reviewed Occupancy patterns are known to strongly affect the number of people killed by earthquakes. Existing exposure models for Europe based on housing census do not account for the daily movement of the population between the place of residence (residential occupancy) and places of economic activity (non-residential occupancy), or the seasonal patterns due to tourism. This study presents a framework to upgrade exposure models from static to 'dynamic', i.e., allowing the input population to change in time and space based on daily and monthly population movement patterns. Open-source population data is used to disaggregate and rescale occupants inside residential, commercial and industrial buildings of 28 European countries, resulting in 24 occupancy categories: two times (i.e., day and night) x 12 months at 30 arc-seconds resolution. The static vs dynamic exposure models are compared using the number and distribution of fatalities resulting from loss calculations for a stochastic set of earthquakes generated from the European Seismic Hazard model (ESHM20). The results demonstrate that the spatiotemporal patterns of population can significantly impact earthquake mortality rates and should not be neglected in scenario loss assessment. The results also demonstrate that the worst occurrence time depends on both the distribution of indoor population between building occupancies and the earthquake rupture characteristics. The ability to capture population distribution during the day and night or seasonal changes (e.g., winter vs summer) is a feature that can advance the ongoing rapid damage/loss assessment services in Europe and consequently support emergency response planning.

News FORCE project: Groundwork activities gain strong support from local and national stakeholders in Nepal By: Apr 11, 2023 Share Facebook LinkedIn FORCE project: Groundwork activities gain strong support from local and national stakeholders in Nepa l GEM’s USAID-supported Forecasting and Communicating Earthquake Hazard and Risk (FORCE) project kicked off in Kathmandu, Nepal from February 20th to 24th by meeting local and national partners involved in disaster risk reduction activities in the country. A half-day introductory workshop for key project stakeholders on February 24th capped the groundwork activities. GEM, represented by Catalina Yepes and Alejandro Calderon, and GEM public sponsor - the National Society for Earthquake Technology (NSET), represented by Executive Director Surya Shrestha and its key officers, coordinated and participated in the kick-off activities. Discussions with different stakeholders focused on the following project goals in the country: to improve earthquake risk assessment practices; to introduce a temporal component in the global exposure model that would enable the quantification of future disaster losses, including those associated with climate change; and to develop communication and dissemination tools to maximize the uptake of disaster risk information in policy making. The discussions also highlighted the following priorities and challenges: need to unify numerous studies available in the country; need for an inter-governmental strategy to share, use and maintain information; need for a centralized system of open and transparent models (NDRRMA indicated the mandate to create a platform for this purpose); Importance of social vulnerability data for decision-makers and stakeholders, which the project must explore with the Statistical Office of Nepal. Discussions also focused on the challenges and the need to clearly communicate the outputs and results of the project to the relevant authorities and the general audience. The National Disaster Risk Reduction and Management Authority (NDRRMA), Nepal’s governmental institution with the mandate to provide information on earthquake risk in the country, sees three main areas of collaboration for the project that could address some of the challenges discussed: 1) technical training; 2) unifying and updating the existing risk information and models; and 3) using FORCE outcomes for current and future risk forecasts at the municipal level. Moving forward NDRRMA will be the main governmental institution for coordinating the project activities and will lead in facilitating access to existing data and surveys in the country, as well as the maintenance, distribution and communication of project outcomes to the relevant government offices and the public at large. NSET and GEM will be the main technical support for developing and updating the models, in close collaboration with academic institutions where possible.
