Publications Exposure model for European seismic risk assessment Share Facebook LinkedIn Download 2020 | Peer-reviewed Building exposure and vulnerability models for seismic risk assessment have been the focus of a number of European projects in recent years, but there has never been a concerted effort among the research community to produce a uniform European risk model. The European Commission’s Horizon 2020 SERA project has a work package that is dedicated to that objective, through the development of an exposure model, an associated set of fragility/vulnerability models, and a database of socioeconomic indicators in order to calculate probabilistic integrated seismic risk at a European scale. This article provides details of the development of the first versions of the European exposure model that describe the distribution of the main residential, industrial and commercial building classes across all countries in Europe, as well as their occupants and replacement costs. The v0.1 of the European exposure model has been integrated within the Global Earthquake Model’s global exposure and risk maps. Preliminary analyses using the model show that almost 35% of the residential population in Europe is exposed to a 475-year return period peak ground acceleration (PGA) hazard of at least 0.1 g, thus highlighting the importance of European seismic risk modeling and mitigation.

Publications A brief overview of the past, present and future of the Global Earthquake Model (GEM) Foundation Share Facebook LinkedIn Download 2024 | Peer-reviewed The Global Earthquake Model (GEM) is an initiative that originally emerged from discussions and proposals made by the Global Science Forum of the Organization for Economic Co-operation and Development (OECD) in the early 2000’s. In 2009, GEM established itself as a non-profit legal entity, the GEM Foundation, and 15 years later, it continues to operate globally with a mission to provide transparent resources for seismic hazard and risk assessment, as well as to support disaster risk reduction for a wide range of natural hazards. This paper highlights the main milestones from the past 15 years and the vision of the foundation to 2030. An overview is also provided of the status of GEM products and services, all of which are made available for the benefit of society, under a strategy that aims to assure the continued financial sustainability of the organization.

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.
