How seismic is Osilo: zone 4

Zone4
Seismic zone 4

The quietest class: the probability of strong earthquakes is very low.

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

The national hazard map provides no value for this area: that happens in the quietest parts of Italy.

Hazard describes the long-term expected shaking: it is not a forecast.

Why the ground rarely shakes here

Osilo 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.
