The Irpinia earthquake of 23 November 1980

On 23 November 1980, at 19:34, a powerful earthquake measuring 6.9 on the Richter scale struck the Campania-Lucania Apennines, affecting a vast area of Campania and Basilicata and, to a lesser extent, Puglia. According to reconstructions by the National Institute of Geophysics and Volcanology (INGV), this was not a single ‘simple’ tremor but a sequence of closely spaced sub-events which, in less than a minute, involved several fault segments, thereby widening the extent of the damage.
During the night, knowledge of the disaster remained incomplete, and it was only at dawn the following day that a more reliable picture of the destruction began to emerge.
The damage was extensive: 2,734 fatalities, around 9,000 injured and 280,000 displaced. These figures became the tangible sign of a prolonged crisis in housing, social care and healthcare.
Added to this was the collapse of public service networks: electricity and telephone lines were severed, cutting off communications with the centre, and rail services came to a standstill, leaving the peninsula ‘cut in two’. The isolation of many inland areas exacerbated the emergency and hampered the arrival of relief efforts.
The loss of life was accompanied by the destruction of entire communities: fifteen villages were almost completely destroyed (including Sant’Angelo dei Lombardi, Lioni, Conza della Campania, Castelnuovo di Conza, Balvano, Calabritto, Caposele, Teora, Torella dei Lombardi, Pescopagano and Senerchia), whilst hundreds of other towns and villages suffered severe or widespread damage.
In administrative terms, 688 municipalities suffered severe damage, and around half of these lost their entire housing stock, with houses and buildings having collapsed and historic centres left in ruins.
The impact was exacerbated by secondary effects: the tremors triggered numerous landslides, some of which were massive (Calitri, Caposele, Calabritto, Senerchia), contributing to the isolation of inland areas and the proliferation of territorial crises.
