How seismic is Petrosino: zone 2
A zone where strong earthquakes are possible: new buildings follow strict anti-seismic criteria.
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 = 0.051 g (10% probability of exceedance in 50 years, rigid soil).
Why the ground rarely shakes here
Petrosino 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.
“Within 30 km”: epicentres less than 30 km from the centre of Petrosino. “In the town”: quakes whose nearest town to the epicentre is Petrosino.
