GEM Models and OpenQuake Engine Training
May 5-16, 2025
EUCENTRE, Pavia, Italy

OVERVIEW
This course, part of the Doctoral Programme in Earthquake Engineering at IUSS Pavia, is organised by the Global Earthquake Model (GEM) Foundation, and aims to provide a comprehensive overview of state-of-the-art methods and models for seismic hazard, exposure, vulnerability and risk assessment, and their implementation within the OpenQuake Engine under a number of different use cases. The course will include both theoretical lectures and training sessions on how to use the OpenQuake Engine, from basic scenario analysis to advanced modelling of probabilistic seismic hazard and risk.
