Publications GEM: a Participatory Framework for Open, State-of-the-Art Models and Tools for Earthquake Risk Assessment Share Facebook LinkedIn Download 2012 | Peer-reviewed The Global Earthquake Model (GEM) initiative aims to develop a global model of earthquake risk as an open source, community-driven project. In order to begin this in a structured way, a number of global components that cover the scientific modules of the model were defined and international consortia were invited to bid and lead these their development. These consortia define standards and best practice related to the methodologies used in seismic hazard and risk assessment and in particular the collection and storage of data needed therein. This paper introduces these global components and describes an open source platform for risk assessment OpenQuake that is being developed to provide access to and interaction with the proposed data and tools.

Publications GEM Strategic Plan and Roadmap to 2030 Share Facebook LinkedIn Download 2022 | Brochure GEM was founded in 2009 with the purpose of improving the global knowledge of earthquake risk and contributing to the reduction of risk worldwide. In more than a decade, GEM has become widely known for its global effort to improve the state of practice of earthquake hazard and risk assessment and for its contribution to improving the state of knowledge of earthquake risk. Overview

A 100,000 year global stochastic catalogue of earthquake events Products Global Stochastic Catalogue A 100,000 year global stochastic catalogue of earthquake events Share Facebook LinkedIn Description The Stochastic EvEnt Sets At Worldwide Scale (SEESAWS) project started in 2024 with the aim of creating a global dataset of ruptures from the GEM Hazard Mosaic that could be used in hazard and risk calculations to generate ground motion fields (GMFs) at a global scale. A significant effort has been devoted to ensuring that the ruptures derived from the hazard models included in the GEM Mosaic were consistent with our understanding of regional tectonics, to eliminating abrupt transitions at the borders between models, and to producing a consistent orientation of ruptures across Mosaic model boundaries. This has led to a Global Stochastic Catalogue representing 100,000 years of seismicity based on the 2026 GEM Hazard Mosaic and including all ruptures with magnitudes M ≥ 5.

News The Global Earthquake Model (GEM) Foundation Launched ATLAS 2.0! By: Jul 8, 2024 Apr 19, 2024 Share Facebook LinkedIn The GEM Foundation successfully launched its next-generation seismic hazard data service, ATLAS 2.0, on April 17th, 2024. Nearly 100 attendees joined the virtual launch event to learn about this exciting update. Building on the original ATLAS service, ATLAS 2.0 offers an even more robust and user-friendly dataset of global seismic hazard curves. Designed for both public benefit and commercial applications, this valuable resource allows users to conduct earthquake risk assessments for various return periods on portfolios around the world. The launch event recording, along with additional information about ATLAS 2.0, can be accessed here: https://www.globalquakemodel.org/gemevents/atlas-2-unveiling-2024-webinar . This includes details about the improved technical specifications of the dataset, leveraging the latest iteration of GEM's Global Seismic Hazard Mosaic. Watch ATLAS in action Paul Henshaw, GEM Director of Technology and Development explains the innovative IT infrastructure that facilitates seamless access and integration of ATLAS 2.0 into external frameworks. https://www.youtube.com/watch?v=l5O1hvSugDA https://www.youtube.com/watch?v=l5O1hvSugDA&t=1298s Discover how others are using ATLAS 2.0 Stevan Gavrilovic, an engineer at Arup, presented a testimonial for the GEM Foundation's ATLAS 2.0 application during the launch. Arup is a structural engineering firm that incorporates seismic hazards into their risk and resilience assessments. They automate this workflow using a cloud-based risk platform they call "HAPPY." A key component of this platform is the GEM ATLAS 2.0 service, which provides global seismic hazard curves through an API (Application Programming Interface). "At Arup, we leverage GEM ATLAS’ global seismic data to automate risk assessments, providing our clients with a clearer view of potential losses across their portfolios." – Stevan Gavrilovic, PhD, Digital Risk and Resilience Engineer-Arup https://www.youtube.com/watch?v=l5O1hvSugDA https://www.youtube.com/watch?v=l5O1hvSugDA&t=1980s We encourage you to explore ATLAS 2.0 and share your thoughts! This powerful tool can be used for various purposes, from earthquake risk assessment to seismic design and land-use planning. URL: https://www.globalquakemodel.org/products/atlas No images found.

News GEM at UR24: Advancing Global Resilience through Collaborative Efforts By: Jun 25, 2024 Jun 25, 2024 Share Facebook LinkedIn The Global Earthquake Model (GEM) Foundation showcased its leadership in seismic hazard and risk assessment at the Understanding Risk Global Forum 2024 (UR24) held in Himeji, Japan from June 16-21, and organised by the Global Facility for Disaster Reduction and Recovery (GFDRR). This event provided an invaluable platform for GEM to share insights, promote collaboration, and reinforce global resilience against geohazards. Building a Global Community for Geohazards Risk Assessment On June 20, GEM concluded its activities with a successful focus day session titled "What about Geohazards? Building a Global Community for Hazard and Risk Assessment." Convened by John Schneider, Senior Advisor, GEM; Malaika Ulmi, Geological Survey of Canada; and Gill Jolly, GNS Science NZ, this session brought together experts from organisations such as USAID, USGS, GNS Science, PHIVOLCS, and NASA. It built upon the discussions from the June 18th session, "What About Geohazards? The State of Practice in Risk Assessment and Needs for Improvement at National to Sub-National Level," where contributions from Nicolas Pondard (The World Bank) and Renato Solidum (Secretary of the Department of Science and Technology, Philippines) were crucial. The June 20th session focused on establishing a globally coordinated network to improve access to information and expertise in geohazards risk assessment and promote collaboration to strengthen capacities in developing countries. There was widespread interest from attendees for such an initiative, highlighting the importance of a committed community of experts working together to drive significant advancements in understanding and mitigating natural hazard risks. Exploring Future Directions for Disaster Scenarios Another key session, "Can ‘Seeing’ the Future Help us Change it?", organised by GeoHazards International and featuring GEM’s Helen Crowley, underscored the power of disaster scenarios. The session demonstrated how co-producing scenarios with stakeholders can help connect technical understanding of risk with locally sustainable actions, including new policies, mitigation, and preparedness. Key takeaways included the importance of effective co-creation with communities, leveraging recent research insights, and transforming scenarios into practical and actionable mitigation strategies. First Day Success and Continued Engagement On the first day of UR24, GEM Secretary General Helen Crowley played a key role in two significant sessions: the plenary session "Richter Resilience: Advancing Seismic Protection Worldwide" and "Symphony of Tradition and Innovation: Orchestrating Global Resilience in Diverse Communities", organised by ImageCat. Both sessions addressed crucial aspects of earthquake resilience, combining tradition with modern advancements to foster a resilient future. Watch Helen’s plenary presentation below. https://www.youtube.com/watch?v=EbhmnmeWuMc Engagement at the Exhibition Booth Throughout the forum, GEM maintained a strong presence at booth S7, where attendees could engage with GEM's Product Manager, Andres Abarca, and earthquake experts, including Marco Pagani, Head of Seismic Hazards. The booth showcased GEM’s latest tools and methodologies for earthquake hazard and risk assessment, providing valuable insights into driving global earthquake preparedness and resilience. From left: Marco Pagani, Helen Crowley, Andres Abarca and John Schneider UR24 has underscored GEM's commitment to global collaboration and innovation in geohazards risk assessment. Through its active participation and leadership, GEM continues to pave the way for a more resilient future against seismic threats.
