News GEM's IDDRR Event Recap - Unveiling Global Earthquake Hazard and Risk Products By: Dec 14, 2023 Oct 13, 2023 Share Facebook LinkedIn October 13, 2023. In a time when disaster risks are inextricably linked with inequalities, the Global Earthquake Model (GEM) Foundation continues to make strides in addressing this critical issue. GEM’s global earthquake hazard and risk products, introduced on International Day for Disaster Risk Reduction 2023, are expected to contribute to disaster risk management efforts globally, helping reduce vulnerabilities, and promoting equity. Highlighting Inequality and Disaster Risk The UN’s International Day for Disaster Risk Reduction (IDDRR) for 2023 focused on the nexus between disaster risks and inequality. It emphasised how unequal access to resources and insurance often leaves the most vulnerable communities exposed to catastrophe. Additionally, disasters tend to exacerbate disparities, plunging marginalised communities further into poverty. GEM's Contribution to Risk Reduction GEM's newly released global earthquake hazard and risk products are key contributors to addressing this challenge. They provide vital insights into the world's varying risk landscape. This, in turn, equips risk managers, insurers, engineers, building regulators, and community planners with the data they need to formulate effective risk reduction strategies. These strategies encompass improving building safety and land use, enhancing earthquake preparedness, and incentivising risk transfer mechanisms such as insurance. IDDRR 2023 Event Highlights The GEM event featured several presentations from the secretariat team with Helen Crowley, GEM's Secretary General, leading the event and providing an introductory address, setting the stage for discussions on global earthquake hazard and risk. Innovative global flagship products were unveiled, including global seismic hazard and risk mosaics; over 200 updated national exposure and vulnerability models, and country seismic profiles; interactive geoviewers, and downloadable high-resolution image files of the global maps, promising to transform disaster risk management on a global scale. About 250 attendees from 52 countries were guided through accessing and effectively utilising GEM's new and improved products page.

Publications Modeling distributed seismicity for probabilistic seismic_hazard analysis: Implementation and insights with the OpenQuake engine Share Facebook LinkedIn Download 2014 | Peer-reviewed In any probabilistic seismic‐hazard model, the earthquake activity that cannot be associated with well‐characterized fault structures is taken into account as seismicity distributed over a geographical region. Ground‐motion prediction equations (GMPEs) are generally based on predictor variables describing the spatial extension of a rupture. The approach taken to model rupture finiteness can therefore bias the estimation of seismic hazard. We study the effect of rupture finiteness in modeling distributed seismicity using the OpenQuake (OQ) engine, the open‐source software for seismic hazard and risk assessment promoted by the Global Earthquake Model initiative. For a simple test case we show how the inclusion of rupture finiteness, with respect to the point‐rupture approximation, leads to a significant increase in the probabilities of exceedance for a given level of motion. We then compare the OQ engine with the calculation software developed by the U.S. Geological Survey‐National Seismic Hazard Mapping Project. By considering a gridded seismicity model for California, we show how different approaches for modeling finite ruptures affect seismic‐hazard estimates. We show how sensitivity to rupture finiteness depends not only on the spatial distribution of activity rates but also on the GMPE model. Considering two sites in Los Angeles and San Francisco, we show that for a return period of 475 years, the percent difference in the associated ground‐motion levels when using point and finite ruptures ranges from 19% to 46%; for a return period of 2475 years the difference ranges from 29% to 58%.

News A UNISDR survey is underway to help develop an international framework for sharing risk information and promoting a pro-active culture of risk-informed decision-making By: Mar 20, 2019 Share Facebook LinkedIn The UNISDR is currently conducting a survey to inform the development of a Global Risk Assessment Framework (GRAF). The information will be used to develop an initial assessment and understanding of the profiles of potential users of GRAF and their needs (existing and anticipated) with the goal of establishing an international framework for developing and sharing risk information and promoting a pro-active culture of risk-informed decision-making. The survey was developed by the GRAF Mapping & Gap Analysis Working Group, co-led by John Schneider (GEM) and John Rees (BGS representative the GEM Governing Board), which is providing expert advice to the the UNISDR on the GRAF. Inasmuch as GEM itself is a part of the envisaged GRAF, GEM also aims to use the results of the survey to inform GEM’s strategic planning process. Therefore, for the benefit of the GRAF and GEM, we would very much appreciate your filling out the questionnaire. The GRAF and GEM would like to better understand: how your organisation is perceiving the barriers and opportunities for leveraging disaster risk management from different angles, including: i. Geographic scales – from global, national, sub-national, to local; ii. Risk dimensions – hazard, exposure and vulnerability; iii. Impact dimensions – human, ecological, economic, infrastructural and political. The questionnaire has nine questions and takes about 10-20 minutes to complete. We would very much appreciate your responses by 1st April. Thank you in advance for your participation. << TAKE THE SURVEY >> No images found. GALLERY 1/4 VIDEO RELATED CONTENTS

Publications The communication strategy for the release of the first European Seismic Risk Model and the updated European Seismic Hazard Model Share Facebook LinkedIn Download 2024 | Peer-reviewed To design user-centred and scientifically high-quality outreach products to inform about earthquake-related hazards and the associated risk, a close collaboration between the model developers and communication experts is needed. In this contribution, we present the communication strategy developed to support the public release of the first openly available European Seismic Risk Model and the updated European Seismic Hazard Model. The backbone of the strategy was the communication concept in which the overall vision, communication principles, target audiences (including personas), key messages, and products were defined. To fulfil the end-users' needs, we conducted two user testing surveys: one for the interactive risk map viewer and one for the risk poster with a special emphasis on the European earthquake risk map. To further ensure that the outreach products are not only understandable and attractive for different target groups but also adequate from a scientific point of view, a two-fold feedback mechanism involving experts in the field was implemented. Through a close collaboration with a network of communication specialists from other institutions supporting the release, additional feedback and exchange of knowledge was enabled. Our insights, gained as part of the release process, can support others in developing user-centred products reviewed by experts in the field to inform about hazard and risk models.
