On the selection of ground motion prediction equations during the assessment of seismic hazard in stable continental regions

Аннотация

In the last decade, the number of ground motion prediction equations (GMPEs) significantly increased due to the higher quality and expansion of networks recording strong ground motions throughout the world. Therefore, the key point in seismic hazard assessment is the selection of a suitable ground motion prediction equation. This work presents the review of the modern state of the problem, the discussion of the criteria for selecting the models to include in the logic tree. The models chosen as part of the big international projects for stable continental regions are described in more detail. Several models have been proposed for use in the stable regions of the central part of the Russian Federation and have been compared. Despite numerous attempts to develop the formal criteria for the selection of a certain model, the construction of the logic tree for each particular problem is based on the expert opinions.
