Alserio, a village on its own lake in the Como Brianza

Lake Alserio is one of the small lakes of the Brianza, the hilly area between Milan and Como, and the village that gives it its name lies on its shore, in the part of the province of Como close to Erba. Around it are low hills, meadows and woods, with houses gathered in a small centre and newer homes around it.

Alserio has grown in recent years. In 2023 it had 1,369 residents, up 16.4% on 2011, or 193 more people. It is a village of families: the average age is 44.0 against 46.3 in the province, 18.5% are over 65 (province: 24.1%) and households average 2.38 people. Declared incomes are above the provincial average.

People who buy here usually work elsewhere, in Erba, Como or the Milan area, and drive. In return they get houses with gardens, detached homes and small blocks of flats in a quiet setting. For houses near the shore, look carefully at the ground: the banks of the Brianza lakes are often low and damp, and the report reads the official flood maps at the address.

Earthquake risk is low. All 147 municipalities in the province of Como are in seismic zone 4, the lowest band, and the expected ground acceleration in Alserio is 0.046 g. In a house from the 1970s or 1980s, insulation, windows and the boiler matter more.

The Revenue Agency's cadastral maps cover the whole municipality, so the report can find the building's plot from the address.

Alserio is a municipality in the province of Como, in Lombardia. At the end of 2023 it had 1,369 residents, ranked 92 of 147 municipalities in the province.

Earthquakes

For Italy's Civil Protection Department, Alserio is in seismic zone 4, the lowest-risk zone, where strong earthquakes are very rare. All 147 municipalities in the province are in the same zone.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.046 g, a low 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.
