The 1980 Irpinia earthquake (Italian: Terremoto dell'Irpinia) took place in Italy on 23 November 1980, with a moment magnitude of 6.9 and a maximum Mercalli intensity of X (Extreme).

The earthquake struck at 18:34 UTC (19:34 local), centered on the village of Castelnuovo di Conza, Campania, Southern Italy.

[6] The study of near-field strong motion and leveling records revealed a complex rupture process comprising three subevents.

The towns of Lioni, Conza della Campania (near the epicenter), and Teora were destroyed, and dozens of structures in Naples were levelled, including a 10-story apartment building.

Of the billions of lire that were earmarked for aid to the victims and rebuilding, the largest part disappeared from the earthquake reconstruction funds in the 1980s.
