Overview and introduction to development of non-ergodic earthquake ground-motion modelsLavrentiadis, Grigorios (Avtor) Babič, Anže (Avtor) Dolšek, Matjaž (Avtor) probabilistic seismic hazard analysisnon-ergodic ground-motion modelGaussian process regressionThis paper provides an overview and introduction to the development of non-ergodic ground-motion models, GMMs. It is intended for a reader who is familiar with the standard approach for developing ergodic GMMs. It starts with a brief summary of the development of ergodic GMMs and then describes different methods that are used in the development of non-ergodic GMMs with an emphasis on Gaussian process (GP) regression, as that is currently the method preferred by most researchers contributing to this special issue. Non-ergodic modeling requires the definition of locations for the source and site characterizing the systematic source and site effects; the non-ergodic domain is divided into cells for describing the systematic path effects. Modeling the cell-specific anelastic attenuation as a GP, and considerations on constraints for extrapolation of the non-ergodic GMMs are also discussed. An updated unifying notation for non-ergodic GMMs is also presented, which has been adopted by the authors of this issue.20232022-09-21 14:09:21Članek v reviji140930UDK: 624.042.7ISSN pri članku: 1570-761XDOI: 10.1007/s10518-022-01485-xCOBISS_ID: 118590723sl
