Bacoli, Baia, Miseno and the ground movement of the Campi Flegrei
Bacoli occupies the western tip of the Campi Flegrei, the volcanic area west of Naples, where Cape Miseno closes off the Gulf of Pozzuoli. Within a few kilometres there are Lake Miseno, Lake Fusaro with the Casina Vanvitelliana hunting lodge, the castle of Baia, the Piscina Mirabilis Roman reservoir and the underwater archaeological park of Baia, where Roman villas slipped under the sea as the ground sank.
It is a seaside municipality with heavy summer tourism: there are 9.72 cafés and restaurants per 1,000 residents, against 4.49 across the province. The villages differ a great deal, from Baia and Miseno on the gulf to Fusaro and Torregaveta on the Cuma side, where the Cumana railway to Naples ends. Many homes are second homes or summer lets.
Bradyseism, the slow rise and fall of the ground, comes first. Bacoli is in the red zone of the Campi Flegrei, the area that the Civil Protection Department plans to evacuate ahead of any eruption. Since 2005 the ground around Pozzuoli has been rising, and the earthquake swarms of recent years have been felt here too. The municipality is in seismic zone 2, with an expected ground acceleration of about 0.165 g, but the national map does not fully capture the shallow local quakes. Buyers should ask whether the building has been inspected after the tremors and have a surveyor assess its structure.
At the end of 2023 Istat, the national statistics office, counted 25,195 residents, down 5.5% since 2011. The town is older than the province of Naples, with over-65s at 23.4% against 20.0% and an average age of 45.7. Foreign nationals make up 1.7%.
The tuff cliffs and the crater slopes can give way, and the report checks this for the address using official maps. The Revenue Agency (Agenzia delle Entrate) publishes the cadastre, so the report goes from the address to the plot.

For anyone buying in Bacoli, the building matters a great deal: ask for the design year, whether it met the 2008 seismic standards, and whether any seismic retrofit has been carried out.
