Zerfaliu, a lowland village on the Tirso near Oristano

Zerfaliu is a lowland village on the bank of the Tirso, Sardinia's main river, a short distance from Oristano. It sits only a few metres above sea level, in farmland of vegetable plots, orchards and irrigated crops that belongs to the Oristano plain. Oristano is close by, and for many residents it is where they work, go to school and deal with paperwork.

Being near the river is the first thing a buyer should think about. The report checks the official flood maps for the exact address, and on a river plain these can change even between two neighbouring streets. Houses are mostly low and detached, many with a yard or a plot of land, and local price bands can be read in the report for each address.

In 2023 Zerfaliu had 980 residents, 192 fewer than the 1,172 of 2011, a fall of 16.4% according to Istat, the national statistics office. Even so, the population is a little younger than the province's: average age 48.4 against 49.8, over-65s at 25.4% against 29.5%. Households average 2.25 people and foreign residents are 1.0%.

The climate is mild (climate zone C), with hot summers and short winters. Earthquake hazard is the lowest on the scale: all 87 municipalities in the province are in seismic zone 4, as classified by the Civil Protection Department, and expected ground acceleration in Zerfaliu is 0.050 g. In older houses, rising damp, roofs and services are what matter most.

The Revenue Agency publishes cadastral maps for the municipality: from the address, the report finds the land parcel.

Overview

Zerfaliu is a municipality in the province of Oristano, in Sardegna. At the end of 2023 it had 980 residents, ranked 40 of 87 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Zerfaliu is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 87 municipalities in the province are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.050 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.

In zone 4 the risk is low, but for an older building it is still worth asking about the state of the structure.
