Castelletto Molina, a small village in the Monferrato hills

Castelletto Molina is a very small village in the Monferrato hills, in the southern part of the province, in a landscape of ridges, farmhouses and provincial roads linking the neighbouring villages. The climate is zone E, with cold winters and fog in the valley bottoms.

Homes on the market are mostly village houses and farmhouses, often with land. Buyers should budget for work on roofs, facades and systems, and check that farm buildings comply with planning and cadastral records before completion. For work, schools and services, people drive to the larger towns in the area.

The population has fallen to 140 residents in 2023 according to Istat, the national statistics office, down 23.9% on the 184 of 2011. The age profile is fairly close to the provincial one, though: the average age is 49.5 (province 47.9) and over-65s make up 24.3%. Foreign residents account for 11.4% and households average 2.19 people. Declared incomes are below the provincial average.

Seismic risk is low: the municipality is in zone 4 of the national classification, like 113 of the 117 municipalities in the province of Asti, with an expected ground acceleration of about 0.054 g.

The Revenue Agency (Agenzia delle Entrate) publishes cadastral maps, which help establish exactly which land and buildings are included in a sale. On hillside plots the report checks the gradient and the official landslide maps for the address.

Overview

Earthquakes

For Italy's Civil Protection Department, Castelletto Molina is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. Most municipalities in the province (113 of 117) are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.054 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.
