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). It left at least 2,483 people dead, at least 7,700 injured, and 250,000 homeless.
The earthquake struck at 18:34 UTC (19:34 local), centered on the village of Castelnuovo di Conza, Campania, Southern Italy. [4] The first jolt was followed by 90 aftershocks. There were three main shocks, each with epicenters in a different place, within 80 seconds. The largest shock registered a peak acceleration of 0.38 g, with 10 seconds of motion greater than 0.1 g. The three main shocks combined produced 70 seconds of shaking greater than 0.01 g. Thus the shaking was severe and lasted a long time. [5]
The focal mechanism corresponded to normal and significant left-lateral strike-slip movement. The rupture dimensions was estimated to be 14 km × 40 km (8.7 mi × 24.9 mi) based on the aftershock distribution. [6] The study of near-field strong motion and leveling records revealed a complex rupture process comprising three subevents. Overall, the rupture on complex fault systems propagated bilaterally along a mostly northwest–southeast trend. [7]
Towns in the province of Avellino were hit the hardest. In Sant'Angelo dei Lombardi, 300 were killed, including 27 children in an orphanage, and 80 percent of the town was destroyed and many historical buildings were left in ruins as the town never fully recovered as of 2021. One hundred were killed in Balvano when a medieval church collapsed during Sunday services. 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. Damage was spread over more than 26,000 km2 (10,000 sq mi), including Naples and Salerno. [5]
The Italian government spent 59 trillion lire (equivalent to €151 billion in 2020) on reconstruction, while other nations sent contributions. West Germany contributed 32 million United States dollars (USD) and the United States US$70 million. [8]
However, in the early 1990s a major corruption scandal emerged. 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. Of the $40 billion spent on earthquake reconstruction, an estimated $20 billion went to create an entirely new social class of millionaires in the region, $6.4 billion went to the criminal Camorra, whereas another $4 billion went to politicians in bribes. Only the remaining $9.6 billion, a quarter of the total amount, was actually spent on people's needs. [9]
The Camorra entered the construction industry after the quake. [10]

Guardia Lombardi, known as La Uàrdia in the Irpinian dialect, is a small town and comune in the Province of Avellino in Campania, Italy. At an elevation of 998 metres (3,274 ft), it is located in Irpinia in the Apennine Mountains of Southern Italy. It has experienced a number of major earthquakes throughout its history that have devastated the town, and is considered within zone 1 of the Protezione Civile's seismic classification index, indicating very high seismicity.
Irpinia is a geographical and cultural region of Southern Italy. It was the inland territory of the ancient Hirpini tribe, and its extent matches approximately today's province of Avellino.
The 1857 Basilicata earthquake occurred on 16 December in the Basilicata region of Italy southeast of the city of Naples. The epicentre was in Montemurro, on the western border of the modern province of Potenza. Several towns were destroyed, and there were around 11,000 fatalities according to official sources, but unofficial estimates suggest that as many as 19,000 died. At the time it was the third-largest known earthquake and has been estimated to have been of magnitude 7.0 on the moment magnitude scale.
Ciro Cirillo was an Italian politician and member of the Christian Democracy (DC) political party. He served as the president of the province of Naples from 1969 to 1975 and the president of Campania from 1979 until 1980. Cirillo oversaw reconstruction efforts in the aftermath of the 1980 Irpinia earthquake, which struck the region on 23 November 1980.
Striking southern Italy on 8 September, the 1905 Calabria earthquake had a moment magnitude of 7.2 and a maximum Mercalli intensity of XI (Extreme). The first major earthquake of the 20th century, it severely damaged parts of Lipari, Messina Province and a large area between Cosenza and Nicotera and killed between 557 and 2,500 people.
The 1694 Irpinia–Basilicata earthquake occurred on 8 September. It caused widespread damage in the Basilicata and Apulia regions of what was then the Kingdom of Naples, resulting in more than 6,000 casualties. The earthquake occurred at 11:40 UTC and lasted between 30 and 60 seconds.
The 1930 Irpinia earthquake occurred at 00:08 UTC on 23 July, chiefly in an area known as Irpinia. It had a surface-wave magnitude of 6.6 and a maximum intensity of X . The event caused 1,404 deaths and 4,624–7,000 injuries. The epicenter was near the boundaries between the regions of Basilicata, Apulia, and Campania.
The 1627 Gargano earthquake struck Gargano and part of Tavoliere, southern Italy, at about mid-day on 30 July 1627. A "very large earthquake" caused a major tsunami, the largest seismic event ever recorded in the Gargano region, which "produced severe damage in the whole promontory", killing about 5,000 people. Four aftershocks were documented. The most extensive damage was noted between San Severo and Lesina.

The 1732 Irpinia earthquake was a seismic event with a magnitude of 6.6 that affected Irpinia and part of Sannio. It occurred on 29 November 1732 at 8:40 AM local time (UTC+1). The epicenter was located in the Campanian Apennines, in the area of the Ufita Valley, which is part of the modern-day Province of Avellino. Around twenty populated areas were destroyed entirely or in part and tens of others were significantly damaged. The number of deaths was estimated to be 1,940. Damage from the earthquake was classified as "severe", and the number of homes destroyed as classified as "many". The earthquake had a rating on the modified Mercalli intensity scale of X (extreme).
Cesina is a toponym of Langobard origin that is used in southern Italy, especially in Campania. It derives from the Latin word caesi and the Latin verb caedere, to which the Langobard suffix -na is added.
On December 5, 1456, the largest earthquake to occur on the Italian Peninsula struck the Kingdom of Naples. The earthquake had an estimated moment magnitude of Mw 7.19–7.4, and was centred near the town of Pontelandolfo in the present-day Province of Benevento, southern Italy. Earning a level of XI (Extreme) on the Modified Mercalli intensity scale, the earthquake caused widespread destruction in central and southern Italy. Estimates of the death toll range greatly with as many as 70,000 deaths reported. It was followed by two strong Mw 7.0 and 6.0 earthquakes to the north on December 30. The earthquake sequence is considered the largest in Italian history, and one of the most studied.
A series of mainshocks struck Calabria on March 27–28 and June 9, 1638. The first three earthquakes had moment magnitudes estimated to be Mw 6.6–7.1. On June 9, another mainshock estimated at Mw 6.7 struck the same region, causing further damage and casualties. The four earthquakes resulted in as many as 30,000 fatalities.
The second shock in the 1962 Irpinia earthquake sequence was the largest and most destructive in a series of earthquakes in the southern Apennines. It occurred on 21 August at 18:19 CET, measuring Mw 6.15 and assigned a maximum intensity of IX (Violent). It was preceded by an Mw 5.68 foreshock, and followed by a 5.34 aftershock. The earthquakes resulted in nearly 20 fatalities and significant property losses.
