How seismic is Delebio: 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.

Very low
Expected shaking, compared with the other Italian municipalities (INGV MPS04 model)

Hazard describes the long-term expected shaking: it is not a forecast. Technical value: ag = 0.046 g (10% probability of exceedance in 50 years, rigid soil).

Why the ground rarely shakes here

Delebio 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.
