People who experienced the ground shaking produced by the November, 23 1980, Irpinia earthquake, consistently report of an intense, long lasting soil vibration. The area of maximum damages had a broad extension (Fig. 1), and the number of victims (about 3000) was anomalously high for a M = 6.9 event as compared to the earthquake losses observed worldwide for similar size events. Although the outdate manufacture of the building estate in the Irpinia region can have contributed to amplify the earthquake effects, the complex, segmented nature of the seismic source has likely been one of the major causes for damage intensity and widespreadness.
