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
Prata Camportaccio 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 Prata Camportaccio plus nearby towns.
