Amplifications of the seismic ground motion in Gemona (NE-Italy): the 1998 Bovec-Krn event as study earthquake

We look at site effects in Gemona (NE Italy) analyzing the waveforms recorded during the 1998 Bovec-Krn (Slovenia) earthquake at three different stations in the town in terms of normalized peak ground accelerations, Arias intensity and response spectra. Then, using a well established numerical approach and a simplified 2D structural model, we estimate site amplifications along a profile underlying Gemona. The simulations agree relatively well with the available observations and some discrepancies can be probably related to the inaccurate knowledge of the subsurface. The results of this study also confirm that our approach can be used for the estimate of site amplifications where the lack of recorded data prevents the evaluation of potential damage of buildings and manufacts
