News GEM Conference 2026: Final Preparations Underway Ahead of June Meeting in Zagreb By: Apr 24, 2026 Apr 24, 2026 Share Facebook LinkedIn University of Zagreb, Croatia, venue of the GEM Conference 2026 With the GEM Conference 2026 now just weeks away, preparations are entering their final stage ahead of the 23–25 June 2026 meeting at the University of Zagreb, Croatia. Registration closed in late February, and the latest overview shows 230 registered participants from 42 countries, representing academia, research institutes, public agencies, the insurance and reinsurance sector, international organisations, consultancy, and a strong cohort of students and early-career researchers. This year’s conference will carry particular significance because Day 1 will mark the release of GEM’s updated global hazard and risk maps, new global seismic hazard datasets, alongside new products on future exposure and risk, infrastructure exposure to liquefaction and the carbon cost of earthquakes. These releases are expected to provide a major update in GEM’s global modelling and data generation. Collectively, they mark an important step in the next phase of GEM’s global modelling framework, updating core reference products while broadening the evidence available for long-term resilience planning and risk-informed decision-making. The registration figures point to broad cross-sector interest, with participants including researchers, engineers, seismologists, risk modellers, government representatives, civil protection and geological agency staff, insurance and reinsurance professionals, consultants, and postgraduate researchers. GEM has also provided 30 fee waivers and an additional 15 travel grants to early-career scientists and researchers from the Global South , helping to broaden inclusivity and widen access to the conference. Many of these participants are also expected to contribute to the programme through presentations, posters and live demos. As the agenda comes together, the three-day programme points to a broad mix of product release, technical exchange and applied discussion. Day 1 will spotlight GEM’s v2026 global hazard and risk release and the science behind it, including new work on global hazard datasets, vulnerability, future exposure and risk, infrastructure exposure to liquefaction, and the carbon cost of earthquakes. Day 2 will focus on exposure and vulnerability modelling, disaster risk reduction applications, financial risk transfer, and a workshop on national seismic hazard models. Day 3 will cover scenarios and cascading hazards, tsunami and post-event assessment, rapid response tools, and further discussion on national hazard modelling. The programme will also feature over 15 live demos and 34 posters . To make the product release sessions available to a wider audience, Day 1 of the conference will be livestreamed via GEM’s YouTube channel. Sessions during the remaining day and a half will be available only to in-person participants, with selected session recordings to be made available after the conference. Readers can find the livestream and other conference information on the event page, including the latest agenda, downloadable materials, floor plans, room layouts, and details on demo and poster locations . Those unable to attend in person are encouraged to follow the Day 1 livestream and circulate the link within their professional networks, helping expand the conference’s main announcements and discussions globally. Register here: Day 1 Livestream Registration A post-conference article in the next newsletter edition will report on the main discussions, releases and outcomes from the Zagreb meeting.

News Strong Response to GEM Public Partnership Call By: Jul 7, 2025 Jun 5, 2025 Share Facebook LinkedIn GEM’s 2025 Public Sponsorship Call has drawn strong interest from around the world, with 14 applications received from 13 countries following the launch webinar held on 10 April. The call aims to expand GEM’s network of public partners committed to advancing earthquake risk understanding and applying science to benefit society. Participants from national geological services, disaster risk agencies and technical institutions joined the April webinar to learn more about GEM’s public sponsorship scheme. The scheme offers access to advanced tools, collaboration opportunities and support in developing national seismic hazard and risk models tailored to local needs. Applications have been received from Mexico, El Salvador, Colombia (2), Uganda, Egypt, Palestine, Jordan, Slovenia, Portugal, Iran, Nepal, Thailand and Indonesia. The proposals reflect a broad range of national priorities in disaster risk management. Focus areas include: Development or updating of national seismic hazard and risk models Integration of earthquake early warning systems Establishment or enhancement of national disaster insurance funds Strategies for safe schools and resilient communities Cost–benefit assessment of retrofitting interventions Use of GEM software and models for rapid impact assessment GEM is now in the shortlisting stage, prioritising proposals that demonstrate strong local ownership, data-sharing commitments, and alignment with GEM’s core values of openness, collaboration and public good. Shortlisted applicants will be contacted by GEM to discuss next steps and potential areas for collaboration, subject to further evaluation and approval. Expanding the public sponsor base is critical to improving global coverage of seismic hazard and risk data – especially in regions where existing information is limited or outdated. Final decisions will be announced later in 2025. For more information, visit the event page or contact info@globalquakemodel.org . No images found. GALLERY 1/0 VIDEO RELATED CONTENTS

News TREQ OpenQuake Online Training: Earthquake Scenarios - Ground Motion Fields By: Sep 21, 2020 Share Facebook LinkedIn The GEM TREQ project team successfully conducted its full OpenQuake online training on September 18th after a series of pilot activities over the last two months. Participants from Argentina, Ecuador, Colombia, Peru, Dominican Republic, Mexico and El Salvador participated in the online training. Catalina Yepes and Alejandro Calderon led and facilitated the first of two sessions for Module II – Part 1: Earthquake Scenarios - Ground Motion Fields. Part 2 is scheduled on September 25th. The Ground Motion Fields session covered concepts in seismic faults, ground shaking intensity, ground motion models (GMPEs) and ground motion fields (GMFs). Facilitators presented and demonstrated how to model a fault rupture in OpenQuake, how to prepare the required input files, how to run various examples, and how to compare results based on the modelling assumptions. A participant from Costa Rica, who has attended previous workshops in person commented “…the workshops have been very good. The online modality has been better than expected. If the sessions are converted into video materials, they would be useful!”. The GEM Risk Team has produced complementary video materials for the workshops, already available on l and currently in use in courses at EAFIT University and University of El Salvador. As part of TREQ’s activities to promote the project, Alejandro Calderon gave a presentation on "Seismic risk assessment using free access tools" upon the invitation of the College of Civil Engineers of Tijuana, through their Center of Continuing Education in Civil Engineering. The webinar was held on August 17, 2020. You can find the presentation (in Spanish) in the following links: The OpenQuake online training initiative is part of the TREQ project activities, led by the GEM Foundation and funded by the U.S. Agency for International Development (USAID). It is designed to build the capacity of risk professionals with a diverse background and expertise, on earthquake risk assessment and the use of the basic features of the OpenQuake engine.
