Figure 1 shows the position of the recording stations of the RAIS (Strong Motion Network of Northern Italy) and RAN (National Strong Motion Network) and the respective values of recorded peak ground acceleration.
A preliminary report of the accelerograms and the response spectra of the RAIS stations can be downloaded here (last accessed 25/05/12), whilst the accelograms and response spectra of the stations of the network RAN can be downloaded from here (last accessed 25/05/12).
