Why the ground rarely shakes here
Alta Valle Intelvi 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 Alta Valle Intelvi plus nearby towns.
