Seismic activity in the surroundings
30 km radiusINGV catalogue epicentres of the last ~12 years, within the given radius from the town centre.
How seismic is this area?
Medium-low seismicity: strong quakes are rare, but not impossible.
Official Civil Protection classification (upd. 2025), used for building codes.
Hazard describes the long-term expected shaking: it is not a forecast. Technical value: ag = 0.050 g (10% probability of exceedance in 50 years, rigid soil).
Why the ground rarely shakes here
Spigno 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 Spigno Monferrato plus nearby towns.
