A site response model has been developed for the European Seismic Risk Model (ESRM20) in order to characterise the ground shaking at the surface at every 30 arc second grid cell in the 44 target countries. Several standalone products have emerged during the development of this site response model: i) a harmonised map of surficial geology, ii) a new European model of inferred VS30 constructed from slope and geology, iii) a database of VS30 observations compiled from multiple sources, iv) ground motion models (and a ground motion model logic tree) for Europe with site scaling terms calibrated on the largest data set of strong motions and site metadata available across the region, which can be adapted to the appropriate context of the calculation. Maps of these datasets can be explored through an interactive viewer. The ground motion models and their corresponding site scaling terms have been implemented in the OpenQuake-engine, and a tool to prepare the OQ-engine site model input files for a given exposure model configuration has also been made available on a GitLab repository. A number of web services are also available for the implementation of automated access to the data and models. Technical details on the development of the site response model for ESRM20 can be found in the Documentation.
