Hosted by GEM from November 14-15, 2023, in Bergamo, Italy, the METIS workshop focused on advancing site-specific seismic hazard assessments. This workshop, attended by more than 80 individuals, aimed to showcase achievements of the METIS project and highlight methodological advancements relevant to site-specific studies.


METIS, an EU Horizon 2020 project, focuses on refining tools and methodologies for seismic safety assessments of nuclear reactors, translating research into practical applications for industry use.


During the event, GEM speakers Anna Rood and Marco Pagani presented insightful topics:


PBR Validation by Anna Rood: Addressing precariously balanced rocks (PBRS), Anna’s presentation emphasised the ground-motion constraints provided by PBRS over extended timescales. She highlighted the need for a multidisciplinary team to validate each realisation of the PSHA model, incorporating uncertainties in fragility and age, ultimately improving the PSHA model logic tree. Watch Anna's presentation below.



New OQ Features within METIS by Marco Pagani: Marco showcased recent enhancements to the OQ Engine, discussing methodological improvements. He described novel approaches such as epistemic uncertainty propagation, vector-valued PSHA, and earthquake sequence modeling for aftershocks, aiming to efficiently handle uncertainties. Watch Marco's presentation below.



The METIS event, a key stage in refining hazard assessment methodologies, concluded with a plenary meeting held from November 16-17. This gathering further fostered collaboration and discussions aimed at advancing seismic hazard assessment methodologies, aligning with METIS' mission to enhance safety assessment tools for critical facilities.
