N2 - The risk assessment of buildings subjected to low-amplitude geothermal-induced (GI) seismic events relays on the knowledge of fragility functions for serviceability and comfort, exposure models and input ground motions. The latter must be specifically estimated for induced seismicity in geothermal reservoirs and differ substantially from those related to tectonic events. The modelling of the input ground motions has an influence on the idealization of the buildings and the soil-structure interaction used for the risk assessment. This contribution addresses open questions about the spectral characteristics and the predominant polarization of the low-amplitude short-duration signals, considering an exemplary seismic data set from the Insheim geothermal reservoirs in Germany. It gives the seismological characteristics, the statistical evaluation of the spectral content and the elastic response spectra for the selected events and sites, and the resulting practical suggestions for the modelling of the input for building risk assessment in case of GI seismicity.
