News Big boost to global risk management with the launch of UNDRR GRAF By: May 23, 2019 Share Facebook LinkedIn GRAF launch at GP2019 Geneva. Photo credit: Gabriela Nobre The UNDRR successfully launched the Global Risk Assessment Framework (GRAF) during the Global Platform for Disaster Risk Reduction 2019 (GP2019) Forum held from 13 – 17 May in Geneva, Switzerland. It is one of the key outcomes of the GP2019 multi-stakeholder Forum. GRAF is a new international framework for developing and sharing risk information and promoting a pro-active culture of risk-informed decision-making. Its objective is to improve the understanding and management of current and future risks, at all scales, to better manage uncertainties and mobilize people, innovation and finance. The GRAF was conceived through a 32-person expert group convened by the UNDRR, with individuals representing the science community, data providers, modellers and risk managers across public and private sectors as well as special interest groups such as youth tasked to help UNISDR develop a comprehensive approach to understanding risk and to apply risk knowledge to generate practical solutions for reducing risk and increasing resilience. Central to this challenge is to create a global collaborative framework for developing, sharing and using risk information across hazards, disciplines, and geographic scales (i.e, global to local), leveraging existing institutions and collaboration frameworks and addressing the systemic nature of risk and its cascading effects. GRAF has four working groups, one of which is Mapping & Gap Analysis, co-chaired by GEM Secretary General, John Schneider and Governing Board Member, John Rees (British Geological Survey). The working group is providing expert advice to GRAF on understanding stakeholder needs as risk assessment information providers and users. “The GRAF is great opportunity to bring cohesion to the risk assessment community to help national governments in support of Sendai risk indicators and targets.” said John Schneider, GEM Secretary General. He added, “GEM is proud of its contributions to the successful establishment and launching of GRAF. We will continue to support GRAF to ensure risk information is shared and promoted to build a pro-active culture of risk-informed decision-making.” Ms. Gabriela Guimarães Nobre, Representative of the United Nations Major Group for Children and Youth moderated the presentation of GRAF on 16thMay to an appreciative audience with high expectations. Session speakers included Mr. David Green, Program Manager, Disaster Applications for National Aeronautics and Space Administration, United States of America; Dr. Renato U. Solidum Jr., Undersecretary, Department of Science and Technology (DOST), Philippines; Dr. Kirsten Dunlop, Chief Executive Officer Climate-KIC; Ms. Kathy Baughman McLeod, Senior Vice President Bank of America; and Mr. Aromar Revi, Director, Indian Institute for Human Settlements; and Co-Chair, UNSDSN. The 4th Meeting of the Expert Group will be held in November 2019 to map the Framework’s plan of action in the years ahead.

News GEM: set to release its new global earthquake hazard and risk models in June By: Apr 11, 2023 Share Facebook LinkedIn In December 2018, GEM released the Global Earthquake Hazard and Risk maps to the public, viewed by industry experts as a major milestone in developing a unified view of seismic risk. Since then, the global maps have been downloaded thousands of times and the data behind the maps have also been publicly released. Furthermore, other products derived from the global models i.e. Atlas 1.0 – an interactive global seismic hazard map, and the comprehensive and simplified hazard maps available from GEM and distributor platforms were also released in the succeeding years. After four years, GEM is set to release the new global earthquake hazard and risk models, maps, and databases through an international conference on June 13th in Bergamo, Italy. The conference will bring leading researchers and risk management experts worldwide together to discuss recent developments and future directions on the road to earthquake resilience. What’s New? -The global earthquake hazard model- The Global Hazard Mosaic consists of 31 models covering the globe, each of which is maintained in its own repository that includes the model input files, and a set of precomputed hazard results (hazard curves, hazard maps, and uniform hazard spectra). “The hazard team performed a large-scale update on all the existing models, in which the team improved the homogeneity among independent models, we used a new reference grid ( https://h3geo.org/ ) and increased spatial resolution of the sites at which results are computed. We also extended the intensity measure levels (IMLs) in the hazard curves to higher values, and included more intensity measure types (IMTs) in the hazard outputs”, said Marco Pagani, Hazard Team Coordinator, on what’s new in the 2023 version of the global seismic hazard. -The global earthquake risk model- Vitor Silva, Risk Team Coordinator on what’s new with the seismic risk model that will be presented in June said: “Practically everything. Starting with the exposure component, dozens of new datasets have been incorporated into the national exposure models, and a new algorithm to spatially disaggregate the assets has been implemented. Moreover, given the large inflation observed in the last years and the rapid population growth in some parts of the world, the cost and number of buildings have been updated globally”. “On the vulnerability side, additional classes have been added to better represent local construction practices, and now the building vulnerability and the vulnerability of contents are evaluated separately. Several adjustments have also been implemented based on the development of earthquake scenarios considering the characteristics of past events. Finally, improvements in the hazard models are also reflected in the risk results.” Vitor further added that the new global seismic risk model covers additional risk metrics, some of them focusing more on the human impact, such as human losses and injuries, or the population left homeless. Furthermore, significant efforts have been devoted to the documentation of specific parts of the world, as well as to the collection of data from past events, which is fundamental for the proper verification, validation and calibration of the models. Details of both the hazard and risk models and much more will be discussed at the Conference in June! ---------- The event is by invitation only for in-person attendance. It is open for online registration for those who wish to attend virtually. If you would like to attend in person, please contact communication@globalquakemodel.org to request a spot.

Publications GEM: For a safer and earthquake resilient future (brochure) Share Facebook LinkedIn Download 2019 | Brochure Initiated by the OECD’s Global Science Forum, GEM was formed in 2009 as a non-profit foundation in Pavia, Italy, funded through a public-private sponsorship with the vision to create a world that is resilient to earthquakes. GEM’s mission is to become one of the world’s most complete sources of risk resources and a globally accepted standard for seismic risk assessment, whose products are applied in risk management worldwide.

Publications Prospective and retrospective evaluation of five-year earthquake forecast models for California Share Facebook LinkedIn Download 2017 | Peer-reviewed Using a score to generalize the model performance into one numeric value has been one of the most popular approaches to empirically evaluate ground‐motion models (GMMs). This approach has an advantage of simplifying model comparison. We study the effects of data correlation and score variability on the evaluation of GMMs. Most modern GMMs are hierarchical, in which ground motions from the same earthquake are modeled as correlated. We demonstrate, with examples, that incorrect results could occur if such hierarchical GMMs are evaluated by a score that does not duly address the data correlation. We propose to use the multivariate logarithmic score, a natural extension of the widely used univariate logarithmic score (referred to as LLH in the seismological literature), to correctly score hierarchical GMMs. The score variability affects the interpretation of model ranking. We demonstrate that the cluster bootstrap is a better bootstrap strategy, compared with other strategies proposed in the literature, to study the score variability. The bootstrap allows computing two useful quantities: the distinctness index that indicates if two models are truly different given the score variability and the frequency weight, a data‐driven weighting scheme that represents the frequentist’s interpretation of the weight of a logic‐tree branch. The frequency weight has a direct link to the current practice of using multiple GMMs in a probabilistic seismic hazard assessment.
