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 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.

News GEM brings global earthquake risk into wider conversations By: Jul 15, 2026 Jul 15, 2026 Share Facebook LinkedIn GEM participated in a series of conferences, workshops and learning events during the quarter, presenting its latest work on global earthquake risk and contributing to discussions on infrastructure, multi-hazard assessment, exposure modelling and resilience. Secretary General Helen Crowley delivered the keynote “Expanding the Boundaries of Global Earthquake Risk” at three events: the NHERI Computational Symposium , the XII National Congress on Earthquake Engineering in Bogotá , and ICONHIC 2026 . Drawing on GEM’s 2026 global releases, Helen explained how earthquake risk assessment is expanding beyond estimates of ground shaking and economic loss. The work includes a fully global hazard framework covering onshore and offshore seismic sources, earthquake-triggered liquefaction and its effects on infrastructure, embodied carbon loss, and projections of how exposure and vulnerability could change through to 2065. Although the three events had different audiences, the presentations addressed a common question: what information will be needed to understand earthquake risk in a future shaped by changing cities, infrastructure systems and interconnected hazards? At ICONHIC, GEM Postdoctoral Researcher Astha Poudel also presented two studies developed with GEM Infrastructure Risk Lead Catarina Costa through the Portuguese-funded SafeNet project. The studies examined the seismic risk of transportation networks, including secondary hazards, urban road systems and approaches for improving infrastructure resilience. Astha also joined the REUNATECH Summer School in Thessaloniki as a guest lecturer. Her session focused on systemic multi-hazard risk assessment and prompted discussion on how the OpenQuake Engine could be used to analyse multiple hazards and interdependencies. In Tallinn, Physical Vulnerability Lead Al Mouayed Bellah Nafeh participated in the third RENOMIZE consortium meeting . GEM contributed to work on structural simulations, seismic actions and performance assessment within an EU-funded project developing automated and industrialised approaches to building renovation. The future of European seismic risk modelling was discussed at the EPOS–EFEHR workshop at the University of Aveiro. Vitor Silva, Marco Baiguera, Daniel Gomez and Catarina Costa joined 53 participants from 26 institutions to review national risk models, exposure and vulnerability modelling, artificial intelligence applications and the future development of the European Seismic Risk Model. GEM also contributed to two interdisciplinary events. In a Royal Geographical Society webinar , Anirudh Rao explained how national datasets, local surveys and Earth observation can be combined to represent geographic differences in exposure, drawing on work in Türkiye and Bangladesh. [Watch the recording] At the NEXT-GEN Spring School in Pavia , Helen, Vitor and Anirudh presented GEM’s global risk work and the OpenQuake Engine within a programme covering climate change, natural hazards and community resilience. ## No images found.
