Pomarance, Larderello and the steam of the Val di Cecina

Pomarance, in the upper Val di Cecina south of Volterra, covers a very large area of hills, woods and small villages. The main town sits on a low hill at around 370 metres, but much of local life happens in the outlying villages, above all Larderello and Montecerboli, where steam rises from underground and has powered geothermal plants for more than a century.

Geothermal energy also shows up in household bills. In several parts of the municipality buildings are connected to district heating supplied by geothermal heat, which cuts heating costs, so ask whether a property is connected or could be. The landscape includes pipelines along the roads, cooling towers and, on some days, a smell of sulphur. Otherwise distances are those of inland Tuscany: Volterra is close, while Pisa and Siena are more than an hour's drive.

In 2023 there were 5,280 residents, 9.7% fewer than in 2011. The average age is 51.0, against 46.9 for the province of Pisa, and over-65s make up 34.0%, compared with 25.3%. Households average 2.01 people, while foreign residents account for 11.7%. Declared incomes remain below the provincial average.

All 37 municipalities in the province are in seismic zone 3 of the national classification set by the Civil Protection Department. In Pomarance the expected ground acceleration is about 0.140 g, so in the stone houses of the villages it is worth having walls, floors and roofs checked, especially if they have been extended over time.

There are 7 schools on record, 1.33 per 1,000 residents against 0.87 in the province, since such a spread-out area needs schools in several places. Cadastral maps from the Revenue Agency (Agenzia delle Entrate) are available, and on the clay slopes the report checks the official landslide maps for the address.

Key points

  • Home of Larderello, the heart of Tuscan geothermal power.
  • Over-65s at 34.0%, against 25.3% in the province.
  • Geothermal district heating in several areas: ask about a connection.
  • Seismic zone 3, expected acceleration about 0.140 g.

Overview

Pomarance is a municipality in the province of Pisa, in Toscana. At the end of 2023 it had 5,280 residents, ranked 21 of 37 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Pomarance is in seismic zone 3, a zone where strong earthquakes are possible but rare. All 37 municipalities in the province are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.140 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.

Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.

Population

Compared with the 2011 census, the resident population has fallen by 9.7%. The estimated average age is 51 years, higher than the province average (47). 34% of residents are over 65 (the regional figure is 26%). Foreign residents make up 11.7% of the population. On average, a household has 2.0 members.

In tax year 2024, taxpayers in Pomarance declared an average taxable income of 23,392 euros, below the provincial average (25,727 euros). The Italian average is 24,895 euros.

Pomarance is in climate zone D, with 1,874 heating degree days: heating may be switched on from 1 November to 15 April, for up to 12 hours a day. The same table puts the town hall at 370 metres above sea level.

Public transport

How built-up it is

Buildings, roads, car parks and other sealed surfaces cover 2.4% of the land in Pomarance, compared with 7.0% in the province and 6.2% in the region. In 2024 built-up land stayed almost the same.

Radon and contaminated sites

Pomarance is not among the radon priority areas designated by the Regione Toscana in 2025. According to the ISPRA map, the estimated radon emission in the municipality is low. Radon varies from building to building and can only be known by measuring it, especially on ground floors and in basements.

Official databases list one contaminated site, or site still under investigation, in Pomarance, and 18 more have been cleaned up or closed. The report tells you whether one is close to the address.

Landslides and flooding

Landslide and flood hazard changes from one street to the next even within Pomarance: the report checks the address against the ISPRA maps.

House prices

The Revenue Agency's price ranges per square metre (OMI) apply to zones, not to whole municipalities: the report gives the range for the address's zone.

Land registry

The cadastral maps for Pomarance are public: from the address the report finds the sheet and parcel number.

Liveability area by area

The Vicinalia liveability index runs from 0 to 100 and looks at the place, not the people who live there: services within walking distance, transport, green space, natural hazards, air, quiet, buildings and connection. Here it is worked out at the centre of each of the 40 inhabited census areas in Pomarance. Half of the residents live in areas scoring 71 or more.
