Tirreno Centrale [Mare]
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
Arzachena 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 Arzachena plus nearby towns.
