Projects SIGMA3 SeismIc hazard and Ground Motion Assessment Versión en español English version Share Facebook LinkedIn Overview Work Packages Training Dissemination Photos Publications Anchor 6 Overview SIGMA3 is a research and development (R&D) program on SeIsmic hazard and Ground Motion Assessment. It is the 3rd part of a larger R&D initiative initiated in 2011 to support innovation in the field of probabilistic hazard assessment (PSHA). SIGMA3 is fully funded by the industry at 100%. The program grounds its roots in methodological developments, as well as in the identified shortcomings of the two preceding editions, labelled SIGMA and SIGMA2. The previous two programs have led to insightful datasets and models to accompany the inception of probabilistic site-specific PSHA studies in low-to-moderate seismicity areas, such as France, for instance. However, nowadays, additional progress is still needed to reduce epistemic uncertainties and improve confidence in probabilistic seismic hazard studies. To this end, SIGMA3 gathers a group of researchers and engineers actively involved in the seismic hazard community and recognized for their expertise. More details about the project are available here: https://sigma-programs.com/ Objectives The SIGMA program is a Research and Development project about seismic hazard and ground motion. It has the objective to improve data and develop methods necessary to best estimate SHA by producing Hazard levels more adapted to the site. Improve available practices for safety demonstration to get consensus with the largest international community for R&D and industrial applications Improve confidence and accountability in seismic hazard assessments by quantifying and propagating uncertainties on Seismic Source and Ground Motion Characterization Strengthen the link between seismologists and engineers, and share feedback among consortium members Collaborators Steering Committee The Steering Committee handles strategic and technical decision-making in the SIGMA3 program and provides recommendations on the program’s orientation, informed by the Scientific Committee’s expertise.

Projects METIS Methods and Tools Innovation for Seismic Risk Assessment Versión en español English version Share Facebook LinkedIn Overview Outcomes Training Outreach Photos Publications Anchor 6 Background GEM is set to start a 3-year project called METIS or Methods and Tools Innovation for Seismic Risk Assessment funded by the European Commission. The project is part of the Safety margins determination for design basis-exceeding external hazards program. Electricite De France (EDF), a GEM technical collaborator, is coordinating the project which will be implemented in collaboration with 14 other organizations. GEM will contribute to the task on seismic hazard assessment and on PSA Tools and Methodology. In the hazard task, GEM will implement into the OQ Engine methods such as vector-valued probabilistic seismic hazard analysis (PSHA), cluster-based PSHA as well as new methods to propagate epistemic uncertainties. Research will also be carried out in the context of processing earthquake catalogues to remove aftershocks and foreshocks and on testing PSHA models. GEM’s contribution to the PSA Tools and Methodology will concentrate on testing risk results. Duration: 2020 - 2025 More details: https://metis-h2020.eu/ Objectives The objective of METIS is to translate research into practice through rigorous and efficient methodologies and tools to assess seismic safety of NPP (nuclear power plants). It also aims to innovate current practice by combining simulation with experimental data. The research will develop methods to improve the ability to define safety limits for extremely rare events, which go beyond current design analyses (i.e. design extension for earthquakes). The refined seismic PSA (probabilistic safety assessment) is expected to provide meaningful support in defining regulations for safe design of NPP, as well as for assessing plant safety in real-time in case of temporary unavailability of relevant safety equipment or structures.

Projects TREAD daTa and pRocesses in sEismic hAzarD Versión en español English version Share Facebook LinkedIn Overview Anchor 6 Background GEM is one of the partners of the Marie Skłodowska-Curie Actions (MSCA) funded TREAD project, which involves a consortium of 14 academic institutions and 8 private partners of the highest scientific level from 7 European countries. TREAD will train a new generation of seismic hazard scientists to tackle the challenges of earthquake forecasting in complex tectonic contexts such as the Europe and Mediterranean regions. During the 4 year project GEM will host and supervise two PhD students, one working with the hazard team and the other with the risk team, on the following topics: 1. Modelling distributed seismicity under innovative approaches (under joint supervision with the University of Milano, Bicocca, 2. Assessment of the impact of advanced seismic hazard modelling approaches on earthquake risk (under joint supervision with the University of Chieti-Pescara) More information at https://tread-horizon.eu/ . Duration: 2023-2027 Objectives The aim of TREAD is to train a new generation of seismic hazard scientists to tackle the challenges of earthquake forecasting in complex tectonic contexts such as the Europe and Mediterranean regions. A change of paradigm in seismic hazard is necessary to be able to fully account for the specific properties of earthquake source and seismic modes in those areas. For example, to calculate the probability of having multiple earthquake ruptures, the interaction between active faults across various space-time scales needs to be accounted for, as well as the effects of stress transfer and fault-fluid interaction in earthquake triggering. TREAD objectives are: 1) Developing a novel integrative approach to seismic hazard analysis in Europe and the Mediterranean by bridging the gap from small-scale laboratory experiments to large-scale observations. 2) Establishing physics-based earthquake modelling by linking computational modelling of earthquakes from millions of years to fractions of a second. 3) Transferring earthquake geology and computational modelling to hazard and risk assessment adapted to the needs of government, industry and scientific stakeholders.

Projects SOLOMON ISLANDS EXPOSURE Assessing the Risk Exposure of Road Network to Climate and Natural Hazard Risks in Solomon Islands Versión en español English version Share Facebook LinkedIn Overview Anchor 6 Background This project aims to conduct a robust multi-hazard risk assessment of the road network to climate and natural hazards in the Solomon Islands, both historically and under future climate projections. The project includes three main dimensions: - Characterization of the climate and natural hazards - Physical vulnerability of the road network - Multi-criteria criticality analysis The three main outputs are: - Multi-hazard maps - Road network risk exposure analysis (global risk score) - Identification of "first priority" road segments and estimation of their rehabilitation costs The GEM Hazard Team supports the project by computing seismic hazard maps and uses these to produce maps to classify low to high risks of earthquake hazards, according to their intensity and frequency. Duration: 2021 Objectives Many Small Island Developing States (SIDS) share a major common feature: they are among the most exposed nations to natural hazards and climate change. SIDS are also characterized by insularity and geographic remoteness, as well as small geographic area, economies, and population, all of which increase their social and economic vulnerability. This project aims to assist the Solomon Islands to better manage climate and disaster risks by improving the understanding of risk and the use of this information for risk reduction decision-making, and the design and implementation of investments at the provincial and community level.
