News GEM Highlights Open Science Benefits and Challenges at OECD Forum By: Apr 23, 2024 Apr 23, 2024 Share Facebook LinkedIn Photo credit: Gemma Volpicelli GEM Highlights Open Science Benefits and Challenges at OECD Forum Paris, France - April 23, 2024 - The Global Earthquake Model (GEM) Foundation underlined the importance of open science collaboration and future directions at the 50th meeting of the OECD Global Science Forum (GSF) this week, a key platform for discussing international scientific collaboration on global challenges. John Schneider, Senior Advisor at GEM, participated in two key discussions, the evolution of international scientific collaboration on April 22nd, and the importance of Open Science for societal benefit on April 23rd. Shifting Landscape of Collaboration A roundtable discussion at the GSF on April 22nd, focused on research infrastructures and their evolution over time, featured John alongside former GSF chairs. “GEM's experience over the past 15 years exemplifies a significant shift," John noted. "The private sector is actively collaborating and increasingly values open frameworks," he said. This shift reinforces collaboration between public and private entities on resolving common challenges for the public good. John presented the history of GEM as a public-private partnership and non-profit foundation, conceived at one of the OECD GSF workshops in 2004. He presented the importance of its collaboration framework and open approach, and the issues GEM faces in operating in an open framework. Underscoring GEM's contribution, Jerry Sheehan, Director of the OECD Directorate for Science, Technology and Innovation, highlighted it as a success story during the 50th meeting closing summary. This was an excellent acknowledgment of the value of the GSF's work in fostering collaborative research infrastructures. Open Science: Benefits and Actions Needed In a separate Multi-Stakeholder High-Level Dialogue on Open Science on April 23rd, John presented GEM's work in open science, using the OpenQuake Engine, an open-source software for earthquake hazard and risk assessment, as a prime example of successful Open Science practices. "OpenQuake has been essential to developing a shared understanding of earthquake hazard and risk across complex and multi-disciplinary fields," he highlighted. The benefits extend beyond technical aspects including fostering the development of local capabilities to assess earthquake risk, strengthening trust in scientific results, and facilitating risk reduction actions. At the same time, challenges include balancing the availability of free and open data and information with the need to have sustained financial support for the organisation, and developing better legal frameworks and communication surrounding data sharing is needed to encourage more participation in open science. The Multi-Stakeholder High-Level Dialogue on Open Science is part of a larger discussion to strengthen international scientific collaboration. This forum, convened during a meeting of Science and Technology Ministers from around the world, addressed challenges and opportunities for the future of science and international scientific collaboration. Open science, along with other themes like biodiversity, climate change, artificial intelligence, and engaging communities in science, were key topics of discussion. Moving Forward with Open Science John underscored the need for concrete actions to promote Open Science. "We need to provide scientists and legal professionals with better tools and resources to understand and implement open licensing," he said. Developing clear guidelines and promoting successful Open Science projects were also highlighted as ways to encourage broader adoption. Finally, John called for a shift in scientific reward systems, placing greater value on the development and maintenance of open software and data alongside traditional publications. The GEM Foundation sees continued collaboration and open data sharing as essential for advancing earthquake risk assessment. GEM's open data-sharing initiatives have allowed researchers and policymakers around the world to access critical earthquake hazard and risk information. This has facilitated the development of more accurate seismic hazard maps, improved building codes, and enhanced disaster preparedness measures in earthquake-prone regions. By making this data openly available, GEM has played a crucial role in enabling local scientists and researchers and collaborating with communities to better understand and mitigate earthquake risk, ultimately saving lives.

Publications A Seismogenic Slab Source Model for Aotearoa New Zealand Share Facebook LinkedIn Download 2023 | Peer-reviewed Intraslab seismicity within the Hikurangi and Puysegur subduction zones constitutes >50% of recorded (⁠Mw _> 4.0 events) earthquakes in Aotearoa New Zealand. Here, we develop a source model for intraslab seismicity using recently augmented datasets including models of subduction interface geometries, an earthquake catalog, and a regional moment tensor catalog. For the areal zones of uniform seismicity, we consider the whole of each slab, as well as demarcations between shallower (depth ≤40 km) and deeper regions. Thereafter, we evaluate the magnitude–frequency distributions in each zone. To compute smoothed seismicity distributions, we apply a novel quasi‐3D approach that involve: (1) delineation of midslab surfaces (defined by regions of maximum earthquake density), (2) orthogonal projections of hypocenters onto the midslab profiles, (3) uniform gridding of 0.1° down‐dip on the midslab, and (4) application of smoothing kernel on the projected hypocenters. We also develop a model to characterize the focal mechanisms of the intraslab earthquakes using the regional moment tensor catalog. This model has median strike angles subparallel to subduction trenches and median dip angles ≥60° in both the subduction zones. The distribution of rake angles suggests that the Hikurangi slab has an extensional regime in the shallower parts but a compressional regime in the deeper parts, indicative of slab flexure. In contrast, the Puysegur slab predominantly exhibits a compressional regime.

Publications Advancing the Understanding of Earthquake Risk in Portugal Share Facebook LinkedIn Download 2024 | Peer-reviewed The assessment of earthquake risk at the national scale is crucial for the design and implementation of risk reduction measures. Due to its location in the southwest of the Eurasian plate, Portugal is exposed to moderate to strong seismic events, such as the well-known 1755 Lisbon earthquake. We reviewed existing studies covering exposure, seismic hazard, vulnerability, and risk assessment for Portugal, and performed probabilistic seismic hazard and risk analyses for the country using new model components. These include a new exposure model developed for the residential building stock using the 2021 national Building Census Survey, a recent exposure model for commercial and industrial buildings, updated vulnerability functions for 116 building classes, and the recently released European Probabilistic Seismic Hazard model. The seismic risk results include average annual economic losses, fatalities, buildings with complete damage, and population left homeless. These results allowed the identification of the regions in Portugal with the highest earthquake risk, as well as which building classes contribute the most to the overall impact.

News In photos: SATIC Event, OpenQuake Conference, Cali Risk Assessment and Community Awareness Workshops By: Dec 5, 2022 Share Facebook LinkedIn GEM and SIATA Medellin were invited to participate in the Disaster Risk Awareness week in the city of Cali, Colombia, which was held from November 21st to the 25th. During these days a series of workshops to promote awareness of disaster risk to the community was organized by the municipality’s Risk Management Office and Office of Urban Planning (Secretaría de Gestión del Riesgo - SGR and Departamento Administrativo de Planeación - DAP). GEM’s Catalina Yepes and Alejandro Calderon visited the city to present the main findings of the urban risk assessment for the city, performed within the framework of the TREQ Project. The culmination of TREQ’s work was presented to urban planners, risk management officials, first responders, and community leaders in sessions that specialized in each target group. SATIC Event The SATIC (Cali Early Warnings Systems) organized by the SGR, had over 250 individuals in attendance. Most of the attendees were community leaders and the general public that is part of the disaster warning system of the city. The event emphasized the importance of community engagement in the success of SATIC. International speakers complemented the workshop with special presentations, among them Catalina Yepes, who presented the work done in collaboration with the SGR in the past two years regarding the seismic risk for Cali. The event was capped by roundtable dialogues between the community, and the signing of the decree by the Mayor on the generation of the community support group. OpenQuake Technical Workshop with City Officials One entire day was dedicated to the transferring of results and capacity from the GEM team to the risk management officials and academics. More than twenty participants joined from Cali’s SGR, DAP, and regional universities. The participants had the opportunity to discuss the seismic scenarios for Cali, how to replicate risk estimates using OpenQuake tools, and train on using the information repository and risk models. Workshops for the community The SGR, GEM, and SIATA Medellin organized two capacity-building sessions for risk officials, community leaders and first responders. Around 50 individuals participated in these sessions and shared experiences and the knowledge required to understand and mitigate seismic risk. The GEM visit to Cali also marked the start of FORCE project’s commitment to keep and improve the training component for technical and non-technical audiences that started in the TREQ project.

News Why 2026 is a Milestone Year for GEM’s Global Seismic Hazard and Risk Work By: Dec 16, 2025 Nov 19, 2025 Share Facebook LinkedIn The GEM Conference 2026 will coincide with the release of a new suite of global seismic hazard and risk products, marking an important milestone for the Global Earthquake Model (GEM) Foundation. Titled “From Faults to Future Scenarios”, the conference will take place in Zagreb, Croatia, from 23 to 25 June 2026 and will be hosted by the Croatian Centre for Earthquake Engineering at the University of Zagreb Faculty of Engineering. The conference theme reflects two core questions at the centre of seismic risk reduction: where earthquakes are likely to occur, and how their impacts may change over time. The reference to “Faults” highlights the role of fault characterisation in the development of seismic hazard models. A revised version of GEM’s Global Active Fault Database will be released at the conference. “Future Scenarios” refers to GEM’s new global seismic risk narratives extending to 2065. These datasets explore how seismic risk may evolve as cities expand, buildings age, and exposure patterns change, providing a longer-term perspective for planners, engineers and policymakers. “2026 will be an important year for GEM, as we release a new generation of global seismic hazard and risk products,” said Helen Crowley, GEM Secretary General. “The conference brings these datasets together and creates space for discussion on how they can be used to support risk-informed decisions.” Additional global products scheduled for release include a global map of infrastructure exposed to liquefaction and a global map of the carbon cost of earthquakes, linking seismic risk with broader environmental and sustainability considerations. Beyond data releases, the conference will provide a platform for participants to share practical applications of seismic risk information, from national hazard modelling to disaster risk reduction strategies. The programme will include oral presentations and live demonstrations, aimed at bridging research and implementation. Registration for the GEM Conference 2026 is now open. An early bird rate of €200 is available until 31 December 2025, with standard registration priced at €350 until 28 February 2026. A limited number of fee waivers and travel grants are available for early-career scientists from lower/middle-income countries, with the expression of interest for these grants open until 31 December 2025. https://video.wixstatic.com/video/1dcea4_f3295ec006d344ca91949ddfb7fc48f8/720p/mp4/file.mp4 ## No images found.
