Earthquakes in Naples
Naples has one of Europe's most complex natural hazard environments. The city of 3 million sits between the Campi Flegrei caldera to the west (an active supervolcano that has been inflating since 2005) and Mount Vesuvius to the east, while the southern Apennines regularly generate damaging earthquakes.
Why Does Naples Face Earthquake Risk?
Campi Flegrei is one of Europe's most dangerous volcanic systems and generates thousands of small earthquakes during active phases. The 1980 Irpinia earthquake (M6.9) killed 2,914 people east of Naples. The region sits where the African and Eurasian plates converge, creating both volcanic and tectonic hazards simultaneously.
Active Fault Systems
- Southern Apennine Normal Faults
- Campi Flegrei Caldera
- Irpinia Fault
Safety Advice
INGV monitors both tectonic and volcanic seismicity in the Naples region. Campi Flegrei uplift has been increasing since 2005 — residents of Pozzuoli and western Naples should stay informed about volcanic risk through INGV's continuous monitoring.
Historical Earthquake Context
Naples and the surrounding Campania region have been devastated by earthquakes throughout history. The 62 AD earthquake severely damaged Pompeii before the famous Vesuvius eruption. The 1688 Sannio earthquake (M7.0) and the 1980 Irpinia earthquake (M6.9) both killed thousands in the region.

FAQ
Frequently Asked Questions
What is the Campi Flegrei danger in Naples?
Campi Flegrei is a supervolcanic caldera covering the western portion of Naples. It last erupted in 1538 and has been showing signs of unrest since 2005, including ground uplift and increasing earthquake swarms. Scientists monitor it continuously. A major eruption would require evacuation of hundreds of thousands of people.
How seismically active is Naples?
Naples sits in one of Italy's most complex geological zones. The city faces both tectonic earthquakes from the Apennine fault system and volcano-tectonic events from Vesuvius and Campi Flegrei. Multiple damaging earthquakes have struck the Campania region, including the catastrophic 1980 Irpinia earthquake (M6.9) 70 km east of Naples.
Is Naples at risk from a major earthquake?
Yes, Naples faces significant multi-hazard risk: tectonic earthquakes from the Apennines, volcanic unrest at Campi Flegrei (currently at the highest alert level in decades), and the distant but present threat of a Vesuvius eruption. INGV classifies the Naples area as Seismic Zone 2 — moderate to high hazard.
What should I do during an earthquake in Naples?
Drop, Cover, and Hold On. After shaking, follow the Italian Civil Protection (protezionecivile.gov.it) guidance. In the event of a Campi Flegrei eruption combined with seismic activity, follow the official red zone evacuation plan. Download the IT-Alert system on your Italian phone for official warnings.
Where can I see live earthquake data for Naples?
Track earthquakes near Naples on the Earthquake Globe app or at earthquakes.site/map?country=italy. INGV (terremoti.ingv.it) provides real-time Italian data. The Vesuvius Observatory (ov.ingv.it) specifically monitors volcanic and seismic activity for the Naples volcanic complex.
