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?
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
Posada 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 Posada plus nearby towns.

The closest seismic structure
The town lies about 227 km from Northern Africa offshore - East, one of the seismic structures mapped by INGV geologists.
