Quarto, the plain at the heart of the Campi Flegrei

A few decades ago the plain of Quarto was farmland. Ringed by hills in the middle of the Campi Flegrei volcanic area, between Pozzuoli, Marano and the western districts of Naples, it quickly became a town of young families, with houses, small blocks and villas filling what used to be fields.

The first thing to know before buying here is the volcano. Quarto lies inside the Campi Flegrei red zone, the area that the Civil Protection plan would evacuate in the event of an eruption, and in recent years bradyseism, the slow rise of the ground accompanied by frequent small earthquakes, has been felt here too. Before buying, get to know the council's emergency plan and have the building's structure assessed.

Building growth over recent decades was fast and not always within the rules. So before signing the preliminary contract, have a surveyor check that the property has valid planning permits and that what is actually there matches council and land registry records. For Naples there are Circumflegrea trains and the city ring road is close by.

In 2023 there were 41,330 residents, up 5.4% since 2011 according to Istat, the national statistics office. The population is younger than the metropolitan average: a mean age of 41.4, only 17.6% aged over 65 and households of 2.77 people on average. Foreign residents make up 2.1%. Healthcare facilities are scarce, 0.29 per 1,000 residents against 0.60 in the province.

In the national seismic classification Quarto is in zone 2, with expected ground acceleration of about 0.159 g; on top of that come the bradyseism tremors, usually weak but frequent. Recent cracks, doors that no longer close properly or fresh work on walls and floors are all things to ask the seller about and show to a surveyor.

For anyone buying in Quarto, 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.
