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 = 0.048 g (10% probability of exceedance in 50 years, rigid soil).
Why the ground rarely shakes here
Introbio 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 Introbio plus nearby towns.

The closest seismic structure
The town lies about 26 km from Western S-Alps internal thrust, one of the seismic structures mapped by INGV geologists.
