Projects BEYOND BUTTON PUSHING Earthquake Risk Assessment and Sensitivity Analysis for California Versión en español English version Share Facebook LinkedIn Overview Anchor 6 Background The goal of the project was to show how important the quantification of uncertainty is in estimating and understanding California’s earthquake risk using OpenQuake - GEM Foundation’s state-of-the-art open source earthquake hazard and risk assessment software. With OpenQuake’s plug-and-play capabilities, expert users can individually select or substitute every model component, data, and assumption. This feature will help model users and decision makers to: 1) ‘ask the right questions’ when evaluating model results; 2) better interpret risk assessment results and gain trust in model results; and 3) make better risk management decisions. Duration: 2015-2017 Objectives The main objectives of this project are to: Establish representative sets of exposure: ‣ for the San Francisco Bay Area; ‣ for the Southern California region affected by the Shakeout Scenario Choose specific results (risk metrics) to use as a basis for comparison. Produce ‘baseline’ results from OpenQuake, using a ‘control’ set of assumptions. Undertake a thorough sensitivity analysis for the risk estimates for California based on the UCERF3 model by running OpenQuake multiple times, each time varying one assumption or parameter, such as: ‣ earthquake probabilities (controlled by assumptions about fault geometries, slip rates, maximum magnitudes); ‣ ground motion model selection; ‣ vulnerability functions; ‣ site conditions; and ‣ statistical treatment of uncertainty and correlation Beyond the aims stated at the outset of the project as listed above, several additional objectives were achieved during the course of the project, including the following: Implement within OpenQuake the latest seismic hazard model for California based on the recently published Uniform California Earthquake Rupture Forecast version 3 (UCERF3), produced by the U.S. Geological Survey and the Working Group on California Earthquake Probabilities. Calculate the average annual loss estimates for all 8,057 census tracts in California, using the seismic hazard model based on UCERF3. Establish the range (distribution) of scientifically viable results for the chosen risk metrics by accounting for the various uncertainties in the hazard model. Identify the components of the hazard model contributing most to the overall uncertainty in the risk metrics for the different exposure portfolios. Implement a model simplification (‘logic-tree trimming’) software tool to reduce the number of computer runs and greatly speed up the time required for running the risk model for California.

Projects PAPERS Piattaforma Analisi Pericolosità E Rischio Sismico Versión en español English version Share Facebook LinkedIn Overview Anchor 6 Background The Global Earthquake Model (GEM) Foundation has launched the PAPERS project (Piattaforma Analisi Pericolosità E Rischio Sismico), an initiative aimed at developing a new WebGIS platform for scenario hazard and risk assessment in Italy. The project has been funded as one of the cascade grants launched by the High-Performance Computing, Big Data e Quantum Computing Research Centre, one of the five National Centres established by the Italian National Recovery and Resilience Plan (NRRP), under Spoke 5 - Environment and Natural Disasters . The first training workshop of the project related to the use of the OpenQuake engine was successfully conducted online on April 1st, 2025, marking the first in a series of planned training events. This first workshop also served for exploring potential third-party contributions to models that could be integrated into the platform. Objectives PAPERS will enhance seismic risk assessment in Italy through advanced computational techniques and open-source models and tools. The project is organised into three modules, each focusing on a critical objective. The first module involves building the operational platform, leveraging the OpenQuake (OQ) Engine. The integration of High-Performance Computing (HPC) will facilitate complex analyses, while interoperability with external software will streamline data management. The second module focuses on updating Italy’s national exposure models. This involves compiling databases of buildings, critical infrastructure, and distributed networks at different geographic scales in the country. The project will integrate existing models with newly available datasets. This effort will provide a more comprehensive understanding of the seismic vulnerability of the Italian-built environment. As part of the third module, the platform will feature preloaded models of seismic hazard, exposure, and vulnerability, along with a range of earthquake scenarios, including historical earthquakes and events from a stochastic catalog based on the 2020 European Seismic Hazard Model (ESHM20). Alternative risk mitigation strategies will also be explored through dedicated multi-criteria decision-making approaches.
