News News Briefs December 2023: Sponsor-supported projects By: Dec 14, 2023 Dec 14, 2023 Share Facebook LinkedIn Sponsor-supported projects Global Earthquake Scenarios (GEeSe) Project In the GEeSe project, a workflow has been developed for generating ground-motion fields for ISC-GEM catalogue events with Mw > 6.5. Models from the Global Hazard Mosaic are selected based on hypocenter proximity, then sources matching the events are filtered out. The rupture matching algorithm identifies the best-matched ruptures. These generate scenario hazard calculations, considering site conditions. The project aims to expand to consider regional conditioning of ground-motion fields and to provide an accessible dashboard output for users. Recent ad-hoc tests showed promising results, such as for the September 2023 Mw 6.8 Morocco event. Retrace3D Project with Italian Civil Protection Retrace3D, in partnership with the Italian Civil Protection, focuses on seismic hazard modelling in Central Italy, the site of the 2016–2017 earthquake sequence. Using RETRACE-3D's high-res fault model and ASPECT's geodynamics approach, the project characterises earthquake activity and computes seismic hazard using the OpenQuake Engine. The finite-element modelling of the fault system was recently completed. A workflow now calculates seismic moment rates and slip rates for each fault, forming source model files for OpenQuake Engine. COMET/UK Project Update The ongoing COMET collaboration has made significant progress. GEM's focus in this phase involves crafting a preliminary time-independent hazard model for Central Asia, leveraging a fault database from the previous collaboration phase. Progress depends on FERMI, GEM's new fault modelling tool. The next phase aims to develop a time-dependent model, a complex task in earthquake science. GEM is exploring innovative methods to modify earthquake timing within established fault slip rates and regional magnitude-frequency distributions. Initial experiments show promise, although scaling to larger fault networks presents challenges. Business Interruption Project Update Following a request for more work in this space from Guy Carpenter, this project led to the creation of new vulnerability functions for business disruption. These functions were based on results derived from simplified multi-degree-of-freedom systems and component-based models. This new modelling framework was developed to enhance the estimation of damage to nonstructural elements and contents. Real claim data from the 2017 Mexico earthquake was used to validate these models, leading to promising results. Liquefaction Module Upgrades Notable enhancements were made to the OpenQuake-engine's liquefaction module. Recent regional liquefaction occurrence models, like those utilised by the US Geological Survey's ground failure (GF) product and Todorovic and Silva's machine learning-based nonparametric model, were integrated. These models aim to predict ground failure using mapped information, offering improved national-scale liquefaction hazard and risk assessments. Additionally, the engine now supports machine learning-based models through the ONNX Runtime library integration. Risk Assessment and Mitigation Study for Earthquakes in the Yilgarn: Infrastructure, Community, Interdependency (RAMSEY) Project The RAMSEY project in Western Australia aims to understand infrastructure system risks in the Yilgarn region. Focusing on critical infrastructure networks, it assesses vulnerabilities, post-hazard dependencies, and recovery strategies. Despite challenges in formalising partnerships, progress continues. Assessments of community buildings' mitigation measures, impacts of scenario events, and substation vulnerabilities have been made. The next key step in the project is the formal request to Federal government by project partners to be able to share infrastructure information. Taiwan Earthquake Model (TEM) In the latter half of 2023, efforts were dedicated to three primary areas. Firstly, the focus was on developing techniques to detect building footprints via satellite imagery, aimed at refining the mapping of exposure data. Secondly, emphasis was on enhancing the understanding of active faults in continental Southeast Asia, specifically addressing the suggested slip rate heterogeneity along the Red River Fault. Lastly, comprehensive seismic models were proposed for the Myanmar region, incorporating area source geometries and fault alignments for Probabilistic Seismic Hazard Assessment (PSHA). Furthermore, the Japan-Taiwan Exchange Association gave the green light to the proposed Japan-Taiwan collaboration concerning Ryukyu PSHA during the Japan-Taiwan-New Zealand Seismic Hazard Assessment meeting held from November 29 to December 3 in Napier, Aotearoa, New Zealand. Collaboration with the Swiss Seismological Service (ETH Zürich) on the EMME24 model This ongoing work is a crucial part of the Middle East Earthquake Model (EMME24). Its objectives include implementing a probabilistic framework, with updated datasets, harmonised cross-border data, revised tectonics and seismogenic source models, as well as ground motion models. The latter involves using multiple GMPEs and backbone models within a logic tree, all implemented in the OpenQuake Engine. In this semester, progress focused mainly on advancing the EMME24 regional hazard model through ongoing efforts that involve 51 Experts from 12 countries. Weekly discussions have been conducted, addressing various components of the model, different toolkits, and advancements in OpenQuake Engine features. No images found.

News PNG clears the ground for new building codes By: Jul 2, 2018 Share Facebook LinkedIn Papua New Guinea is situated at the edge of what is called the “ring of fire”, within the convergence zone of the Pacific and Australian tectonic plates. Its current seismic zoning map, which was developed in the early 1980s and is included in the national building code, needed a revision. In 2013 the PNG’s Department of Mineral Policy and Geohazards Management began a project in collaboration with Geoscience Australia to re-evaluate the level of seismic hazard in the region and to replace the existing model. Fully funded by the Australian Aid, this project leveraged the OpenQuake- Engine for the hazard assessment, selecting the software among others for its openness, transparency and scalability. Preliminary results of the study are now available (Fig.1); whereas the final results as well as the input models will be released after peer review and publication of the official report. OpenQuake is also used routinely by Port Moresby Geophysical Observatory to generate earthquake ShakeMaps for significant earthquakes in the region. No images found.

News Geospatial is the future By: Jul 2, 2018 Share Facebook LinkedIn The second edition of the European symposium on Free and Open Source Software for Geospatial, which took place on July 15-17 in Como (Italy), was a great occasion for GEM to relate with experts and leading organizations in the field of open data, but also to show progress in the development of its tools. The OpenQuake Platform and the Integrated Risk Toolkit were presented to a diverse and curious audience, impressed by the performance and scalability of the tools. Questions raised were mostly about the value of open data and the importance of communicating open licenses, as often the concept of licensing is associated with commercial activities rather than as a way to release resources to the public. The attendance was excellent, with more than 400 people – the maximum capacity of Aula magna and the presence of distinguished experts in geospatial data (Patrick Hogan from NASA, presenting a project developed in collaboration with the Politecnico di Milano and Georg Gartner, a master in server and operating systems among the others), and for GEM it was a good chance to meet new organizations and potential stakeholders. In the run up to FOSS4G Seoul, which will take place in September 2015, GEM is planning to strengthen the communication of its products and encourage the application of its resources worldwide.

News Future directions for PSHA at local, national and transnational scales workshop By: Jul 2, 2018 Share Facebook LinkedIn More than 160 leading experts on Probabilistic Seismic Hazard Assessment (PSHA) from around the globe participated in the PSHA Workshop held at Lenzburg, Switzerland from September 5th-7th, featuring presentations and posters on practical aspects and currently developing issues on the PSHA process. Discussions revolved around time-dependent analysis, source model validation, and site-specific PSHA within the framework of new engineering requirements and communication of hazard results to both scientific and non-scientific communities. The workshop also provided the chance for the PSHA community to interact and share information about ongoing and future research projects, which were discussed in specific thematic meetings. Marco Pagani, Hazard Coordinator, and Valerio Poggi, Senior Hazard Scientist, attended the meeting on behalf of GEM. Marco, a keynote speaker, also presented ‘Exploring GEM’s Global Mosaic of Hazard Models: Hints for Regional Hazard Modelling’ as an input to this year’s theme: PSHA - Future directions for probabilistic seismic hazard assessment at local, national and transnational scales. The participants received the presentation with much interest sparking a passionate scientific debate on the use and treatment of epistemic uncertainty in regional models, which appears to still be a controversial issue within the community. Though the use and treatment of epistemic uncertainty in regional models was a hotly discussed topic, GEM’s OpenQuake engine received overwhelming positive feedback from the participants. Many of the studies presented by the keynote speakers and posters used the OpenQuake engine. No images found. GALLERY 1/0 VIDEO RELATED CONTENTS

News Geociencias SURA magazine features GEM By: Jul 2, 2018 Share Facebook LinkedIn Suramericana’s new magazine Geociencias SURA featured GEM, OpenQuake and SARA Project (South America Risk Assessment) in its inaugural issue. The magazine, which is intended particularly for South America, aims to share its knowledge and experience of more than 70 years in the insurance industry with its partners and the public. The editorial board believes that Geociencias SURA will be an efficient means to contribute to better management of risks associated with natural disasters, and help public and private organizations become more resilient and sustainable. John Schneider, GEM Secretary General imparts GEM’s collaboration strategy with Geociencias Sura saying, "We believe that the alliance between state, academic and private organizations worldwide is critical in managing natural disasters and preserving lives.” He added that building synergies where everyone involved is convinced of the importance of sharing, being open and working together is as important, if not more important as developing the tools or gathering information itself. The launching of Geociencias SURA magazine is a welcome development in the field of risk information and knowledge sharing and one that GEM, as a long-time partner of Suramericana, is committed to support. The magazine is managed by a specialized team within Suramericana and includes international experts on the relationship between nature and society.

News Hazard Definition launch: Working together to turn our understanding of hazards and risk into solutions to reduce risk By: Sep 21, 2020 Share Facebook LinkedIn The UNDRR-ISC Sendai Hazard Definition and Classification Review Technical Report was officially launched online on 29 July 2020 with John Schneider participating in a high-level panel discussion led by Mami Mitzutori, UN Special Representative for DRR, and Heidi Hackman, CEO of the International Science Council. John was also a member of the report’s technical working group, chaired by Virginia Murray, UK Department of Public Health, where his principal contribution was to review and revise the final report. Accompanying the report are 318 Hazard Information Profiles (HIPs), which were written and reviewed through the contributions of over 500 hundred technical experts globally. GEM took primary responsibility for the development of HIPs for Earthquake and associated subhazards, with GEM scientists Richard Styron, Kendra Johnson and Robin Gee authoring HIPs for ground shaking, liquefaction, surface rupture/fissuring, and subsidence and uplift. The report was developed in response to the challenge of the broad and complex nature of hazards which lack standardized definitions across the world. Standardization and clarification are needed to allow hazard and risk information to be combined and compared, and disaster information to be managed, and accordingly to enhance risk reduction policies and operational risk management practices. The hazard definition project identified the full scope of hazards relevant to the Sendai Framework and developed descriptive and practical definitions of these hazards. John Schneider, GEM Secretary General, participated in the launch to share insights on behalf of the hazard scientific community said, “A significant achievement of this project was to bring the hazard science community together in the context of assessing and understanding risk to inform the global agendas for sustainability, risk reduction and adaptation. In order to do so, it was necessary to broaden the definition of hazards to include human activities.” He further added, “…the hazard definition process demonstrated the importance of linking institutions and networks within an international framework. This framework is necessary to maintain and support the monitoring, analysis, maintenance and dissemination of information. The definition is simply the starting point for that institutional ownerships of hazards, and the definitions are the first step in developing a coordinated process, in developing open and accessible databases, and in developing ultimately consistent guidelines, methodologies and interoperability standards.” “It also meant integrating traditional geological and hydrometeorological hazards which many of us in the DRR community were most familiar with. Together with technological, health, social disruption and environmental degradation, the resulting definitions provide part of the common language for understanding risk to society and provide the basis for developing information methodologies and tools for assessing and understanding risk.” John’s full speech is available . The new report is an important stepping stone for the international community to achieve sustainable development within an increasingly complex, interconnected and systemic risk landscape. One of the key themes to come out of the webinar was the need for science, policy, community and the private sector to work together to achieve the goals of the Sendai Framework. The webinar launched and presented the detailed report, including six targeted recommendations. To watch the webinar, click . No images found. GALLERY 1/0 Gallery VIDEO RELATED CONTENTS

OpenQuake engine input model to perform hazard calculations for Sub-Saharan Africa Products Sub-Saharan Africa Hazard OpenQuake engine input model to perform hazard calculations for Sub-Saharan Africa Share Facebook LinkedIn Description The first version of the hazard model for Sub-Saharan Africa (v2016.0.0) was developed by GEM in collaboration with AfricaArray within the USAID-supported SSAHARA project. The original model is extensively described in Poggi et al. (2017). Since the original version, extended and improved versions were developed by introducing a procedure of earthquake-driven redistribution of activity rates (smoothed seismicity approach) on the previously defined source zones. Moreover, the current model includes now Madagascar, for which an ad-hoc seismicity analysis was carried out. The latest version (v2018.0.1) was used in the computation of the 2026 Global Earthquake Hazard Map.
