News GEM’s next journey: Turning GEM models into products useful for the insurance industry By: Jul 31, 2019 Share Facebook LinkedIn John Schneider (L), Malcolm Haylock, Luis Sousa, Michael Ewald and Dickie Whitaker during a panel discussion at Oasis-Swiss Re Conference, June 2019 The 4th Oasis Conference in conjunction with Swiss Re Institute John Schneider, GEM Secretary General represented GEM at the 4th Oasis Conference held on June 12, 2019 at Swiss Re Next Auditorium, Zurich, Switzerland. The event, organized by Oasis and Swiss Re Institute brought together some of the world’s best natural catastrophe (natcat) risk experts and modelers. The objective of the 1-day event was to learn more about the suite of available models, options to deploy Oasis, and how Oasis technology is developing. It also provided model providers an opportunity to demonstrate tools and models to participants. Discussions also focused on key issues in models, the need for transparency and the future of catastrophe risk modeling. Three GEM collaborators presented how they have applied GEM models, tools and data to their respective risk modelling activities. Michael Ewald, Swiss Re (a project partner and now a Sponsor) demonstrated how GEM’s OpenQuake is being integrated into their earthquake modeling approach, in particular the OQ Hazard Module (stochastic earthquake catalogue and ground motion prediction equations, or GMPEs). Luis Sousa, AIR Worldwide (a founding Governor Sponsor) showed the history of GEM-AIR collaboration, showing examples of how GEM data and model components have been used to inform the development of their own risk models in several areas around the world. Malcolm Haylock, Sunstone Risk Solutions, described his implementation of GEM’s OpenQuake model for Puerto Rico, a prototype that runs on the Oasis modeling platform Flamingo. http://www.sunstonerisk.com/gem/ John presented GEM data, models and other products that are currently available i.e. global earthquake ground shaking loss to buildings and population that the insurance sector can immediately use. John also mentioned that financial loss models in OASIS, Touchtone and Elements would become available over the coming months. In addition to the financial loss models, he mentioned that over the next three years, the capability of OpenQuake would be extended to cover multi-perils, while tools and models would include time dependence, secondary perils and critical infrastructure - components that are vital in the insurance industry. Daniel Martin Eckhart, Swiss Re Institute Advocate, in his summary of the event, mentioned on his blog John’s analogy of turning GEM models into products consumable by the industry: In a way it was John Schneider who found the perfect image for this moment in time – the image of a potato! He shared the journey of GEM (Global Earthquake Model) with a simple visual that showed how it went from farming the land to harvesting to now producing the potato (aka models). Said John: "I view the potato as something that's useful. We produce the best organic potato and it's useful to many people." But, he pointed out, the potato is bland and its real value appears when it is turned into other things. "What we have now is great, but it is not what the insurance industry is used to consuming. The next part of the GEM journey is turning the potato into French fries." The fries then stand for models that are useful (consumable) for the whole industry. Dickie Whitaker, OASIS Chief Operating Officer and Beat Aeberhardt closed the conference. Dickie highlighted the significant progress made, the increasing maturity of the Oasis code base and the sophistication of the work done over a short period of time.

News Celebrating Achievements and Way Forward By: Jul 2, 2018 Share Facebook LinkedIn As GEM’s first Working Programme (2009-2013) draws to a close, the GEM Foundation presents to partners, collaborators and stakeholders worldwide, ”Celebrating achievements & looking forward”, GEM vision document for global earthquake risk assessment and a sustainable future for GEM. ”The document celebrates GEM’s journey from the idea of a handful of determined individuals, to what has now become a global community, a solid reality and an authoritative voice in earthquake risk assessment globally” said Rui Pinho, GEM Secretary-General. Right from its inception, GEM chose the less travelled road to increase earthquake resilience, building its work and community around the principles of openness, transparency, inclusiveness, equitable access, solid science and collaborative work across sectors, geographies, and disciplines. At the end of GEM’s first Working Programme, GEM’s unique approach has proven to be the right one; the breadth and wealth of tools and resources developed and being developed, through the involvement of global scientists and stakeholders, is advancing the science and technology needed for global state-of-the-art seismic hazard and risk modelling, data collection, and risk assessment at scales from global, to regional and national. This strategic document shares the successes but also the challenges and the issues that GEM needs to address as it moves towards its second Working Programme (2014-2018). Long-term impact and sustainability are crucial for the achievement of GEM’s mission. From 2014 onwards, GEM’s focus will shift towards practical implementation, public communication and development of datasets and tools at a local scale, to increase the applicability of the products in the OpenQuake platform for reliable risk mitigation. GEM will look at different collaboration opportunities in order to permeate different levels of risk management, and transfer and translate GEM products into accessible resources at different levels of governance from global to regional, to local. With the support of current and future partners, collaborators and stakeholders worldwide, GEM will continue to engage in a wide range of partnerships to advance the science required to assess the risk of the complex interconnected systems within which we live, and increase resilience to earthquakes globally.

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.
