News OQ Engine used in a nuclear SHA project By: Jul 2, 2018 Share Facebook LinkedIn It is well acknowledged that some facilities, such as the nuclear ones, require particular caution when it comes to the calculation of levels of ground motion to be used for design and risk assessment. In other words, the calculation process for an area selected to host nuclear facilities should comply with some specific requirements in terms of Quality Assurance, along the same line of what is achieved in the model building process through the application of the procedure proposed by the SSHAC (Senior Seismic Hazard Analysis Committee that developed SSHAC guidelines which can be used in the development of PSHA input models or in PSHA studies). Taking as a case study the Thyspunt site in South Africa, where Eskom is planning to build some nuclear power plants, a group of scientists including two members of the GEM hazard team proposed a procedure based on the use of the OpenQuake Engine guaranteeing that minimum quality levels in the calculation of hazard are met. They carried out a study to verify the original logic tree calculations and to compare them against the ones obtained with a different software and an independent implementation. After a wide range of tests, the OQ Engine was able to effectively mimic calculations performed by the previous software proving the reproducibility of original calculations and the consistency between its results and the ones computed with the initial software. The result, besides being an international validation of the OpenQuake-engine, represents an interesting contribution in the field of nuclear applications. It demonstrates quality and effectiveness of the testing process adopted by the development team in the implementation of hazard models as well as in the implementation of the software itself.

News GEM and 100RC partnership to boost earthquake resilience By: Mar 1, 2019 Share Facebook LinkedIn Cities at risk to earthquakes are expected to directly benefit from the partnership between GEM and 100 Resilient Cities – Pioneered by The Rockefeller Foundation (100RC), which is dedicated to helping cities around the world become more resilient to the physical, social and economic shocks and stresses of the 21st century. (source: http://www.100resilientcities.org) The agreement signed in August provides an opportunity for 100RC member cities to understand and address their earthquake risk by working with GEM to incorporate earthquake risk reduction in their resilience strategies and capturing lessons learned to inform other cities. The Global Earthquake Model (GEM) will partner with motivated cities to build their capacity for long-term risk mitigation planning using GEM’s open source OpenQuake software and GEM’s other tools and services. “Our partnership with the 100RC is a great opportunity to share GEM’s open tools, data and technical expertise at the city level. Working together with 100RC is an important step toward achieving GEM’s vision of a world that is resilient to earthquakes.” John Schneider, GEM Secretary General. Cities will receive an ‘Earthquake Risk Thumbnail’, a report providing OpenQuake maps of the city’s or region’s seismic risk comprised of the hazard, and the physical, social and economic risk to the exposed assets and population. 'Thumbnail’ report will propose options for deeper engagement which may include collaboration on data collection, raining local city staff or partners to use GEM’s products and tools, and stakeholder engagement workshops including the Resilience Performance Scorecard (RPS) exercise. Rebecca Laberenne, Associate Director on the Solution Development and Innovation Team at 100RC, underscores the value of partnering with GEM saying, "We are delighted to have GEM Foundation as a 100RC Platform Partner to provide much needed information and technical advice to cities whose buildings and infrastructure are at risk to earthquakes. GEM's approach to collaboration and technical assistance will be very welcomed by cities to gain an understanding of their risks, as well as to assist in identifying appropriate and cost-effective mitigation and risk reduction measures as part of their resilience strategies."

News GEM marks 15 years of the OpenQuake Engine during UN disaster risk reduction day By: Dec 16, 2025 Oct 13, 2025 Share Facebook LinkedIn The Global Earthquake Model (GEM) Foundation marked the 15th anniversary of the OpenQuake Engine with a global webinar held on 13 October 2025, aligning the event with the United Nations International Day for Disaster Risk Reduction (IDDRR). The webinar reflected the 2025 IDDRR theme, “Fund Resilience, Not Disasters”, which emphasises the importance of investing in forward-looking, science-based approaches to reducing disaster losses. The event brought together 130 participants from 45 countries, underlining the global reach of the OpenQuake community. The webinar featured a presentation by Anirudh Rao, author of the paper underpinning the event, who reviewed the evolution of the OpenQuake Engine from its early development into a widely used open-source framework supporting seismic hazard and risk assessment in both research and operational contexts. His presentation outlined how the Engine has expanded over time to support a growing range of applications, while maintaining transparent and reproducible scientific workflows. The session opened with a recorded contribution from Jenty Kirsch-Wood, Head of Global Risk Management and Reporting at the United Nations Office for Disaster Risk Reduction (UNDRR). Her remarks framed the discussion within the objectives of the International Day for Disaster Risk Reduction and highlighted the role of evidence-based tools in guiding resilience-focused investment decisions. A video recording of the full event, including the opening remarks and panel discussion, is available on GEM’s website. https://www.globalquakemodel.org/gemevents/oq-engine-15-iddrr2025 The webinar was moderated by Prof. Iain Stewart, University of Plymouth-UK, and featured a panel discussion with GEM scientists closely involved in the development and use of the OpenQuake Engine, including Catalina Yepes Estrada and Kirsty Bayliss. The discussion reflected on lessons learned from 15 years of open development, the challenges of maintaining scalable and reliable risk models, and the role of open-source tools in supporting disaster risk reduction across different national and regional contexts. External perspectives were provided by Chung-Han Chan, Deputy Director of the E-DREaM Centre at National Central University in Taiwan, and Ana Beatriz Acevedo, Professor in the Civil Engineering Department at EAFIT University in Colombia. Han described how OpenQuake has supported collaboration across disciplines and applications, noting that “from the beginning of the Taiwan Earthquake Model, we chose to work closely using the OpenQuake Engine because it allows hazard scientists and risk modellers to work together using a common framework.” Ana highlighted the importance of usability and real data for training and practice, saying that “OpenQuake makes a difference because it allows us to work with real data and to show how changes in hazard, exposure or vulnerability affect the results.” The webinar was built around the recently published paper “Evolution of the OpenQuake Engine: Enhanced Capabilities, Collaborative Development, and Global Adoption”, published in Earthquake Spectra by Anirudh Rao and co-authors. The discussion linked the evolution and global adoption of the OpenQuake Engine to the 2025 IDDRR theme, highlighting how open, science-based risk models can support more informed investment decisions and contribute to reducing disaster losses over the long term. ## No images found.

News GEM tools well-received in Risk Workshop By: Jul 2, 2018 Share Facebook LinkedIn With capacity building and technology transfer as part of the GEM Foundation's four key strategic priorities, it was heartening to see the enthusiastic and positive response to a range of improvements in both technology and training material at the annual Risk Training Workshop in Pavia in late October, 2015.In a full and intense programme, the GEM Risk Team, led by Vitor Silva, introduced guest speakers from our collaborative partner organisations to inspire participants with practical applications of the GEM tools. For instance, Julia Schaefer explained how our products have been applied by Hannover Re in insurance loss modelling; Barbara Borzi demonstrated how the EUCENTRE uses them for earthquake loss estimation and Surya Shrestha, from Nepal's National Society for Earthquake Technology (NSET), presented their potential applications in post-earthquake recovery. With over 30 participants from around the world, attendees had the chance to not only test the new tools in action, but also to apply them with their own local data in the practical aspects of the training. In a novel approach to post-training support, the Risk Team has developed video materials as an adjunct to the existing technical manuals, to reinforce and refresh the learning once the participants return home. Additionally, discussion with participants has paved the way for further collaborative efforts, with Indonesia, Iran, South Africa and Australia expressing interest in starting or expanding partnerships which will lead to better understanding of earthquake risk and its integration into disaster risk reduction (DRR) planning.

News Linking Livelihood Resilience and Loss & Damage - Resilience Academy Capstone Conference 2017 By: Jul 2, 2018 Share Facebook LinkedIn About 40 experts in resilience, livelihoods and damage due to climate change came from Bangladesh, Colombia, Fiji, India, Germany, Netherlands, Philippines, Romania, Sri Lanka, Sweden, Switzerland, United States of America and the United Kingdom for the fourth Resilience Academy Capstone Conference in Washington, D.C. USA from 16-20 October. This year’s theme ‘Linking Livelihood Resilience and Loss & Damage’ is an emerging topic in climate change negotiations, research, policy and implementation of climate change action. The conference provided a platform for connecting communities of experts in various academic disciplines, practitioners, policy analysts and journalists. It was organized by the Munich Re Foundation, together with the Institute for Climate Change and Development in Bangladesh (ICCCAD), the Institute for Environment and Human Safety at the University of the United Nations (UNU-EHS) and the Woodrow Wilson Center for International Scholars (WWCIS)-Washington D.C., Diana Contreras, GEM Social Vulnerability and Resilience (SVR) team leader presented a case study: The fight of the Wayuu Community against the Drought in La Guajira – Colombia at the conference’s drought thematic session. The presentation focused on the consequences of the drought from 2012 to 2016 due to the El Niño phenomenon and unsustainable water management in the region experienced by the indigenous community Wayuu. Diana further demonstrated how the indicators and tools that were originally collected and designed to estimate social vulnerability (SV) due to earthquakes could be used to estimate SV due to climate change hazards such as drought. Based on the GEM’s tools used for the study, alternative sources of livelihood for the Wayuu indigenous community were identified as climate change adaptive capacity measures. “GEM believes in openness and transparency so all the social variables used in this analysis are publicly available for the scientific community at GEM’s Openquake platform website,” Diana emphasized at the end of the presentation. She further added that models for estimating SV in a given area could be developed using GEM’s Integrated Risk Modeling Toolkit (IRMT) accessible from the QGIS plugin library. No images found.
