How seismic is this area?

Official Civil Protection classification (upd. 2025), used for building codes.

Why the ground rarely shakes here
Altavilla Monferrato sits in one of the most stable areas of Italy: far from the boundary between the Eurasian and African plates, on ancient, rigid crust that hardly accumulates tectonic stress any more.
That is why earthquakes here are rare and almost always weak: a small geological privilege.
The “area” is Altavilla Monferrato plus nearby towns.
