Gonnostramatza, a farming village in the Marmilla

The Marmilla is the district of soft hills and cultivated plains in south-central Sardinia, and Gonnostramatza is one of its farming villages, in the province of Oristano. The town hall stands at about 110 metres, surrounded by cereal fields, vineyards, olive groves and pasture. For services, secondary schools and hospital care, people go to the larger towns in the area and to Oristano.

Most houses in the village are low homes with courtyards, some built in stone or in sun-dried earth bricks following local tradition, others built in recent decades. Earth-brick houses need care: they suffer from damp and from repairs done with the wrong materials, so have them seen by a surveyor who knows them. This is climate zone C, with mild winters and hot summers, so keeping the heat out matters as much as heating.

At the end of 2023 there were 796 residents, 15.6% fewer than the 943 of 2011, according to Istat, the national statistics office. The average age is 50.1, almost the same as the provincial 49.8, and over-65s are 29.0%. Foreign residents are very few, at 0.6%. Households have 2.28 members on average, and average declared income is below the provincial figure.

The earthquake picture is calm: all 87 municipalities in the province of Oristano are in seismic zone 4, and the expected ground acceleration is about 0.050 g. Near the streams and in the lower parts of the village, the report checks the official flood maps for the address.

The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps for Gonnostramatza, and the report links the address to its land parcel.

Overview

Gonnostramatza is a municipality in the province of Oristano, in Sardegna. At the end of 2023 it had 796 residents, ranked 44 of 87 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Gonnostramatza 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.
