He rich seismic history of Sulmona includes eleven earthquakes with Intensity Is≥6 MCS. Considering the different earthquakes with effects beyond the damage threshold, the comparison between the intensities attributed to Sulmona with those of the closer localities indicates that in many cases the town has suffered more severe damage. This suggests that the seismic history of Sulmona may have been conditioned by site effects, thus making more urgent the processing of a modern seismic microzonation. Within this light, an attempt has been made to reconstruct the damage distribution due to historical earthquakes in the old town centre. This practice was aimed at defining damage patterns to be compared with the results of the traditional geological and seismological investigations necessary...
