Why the ground rarely shakes here
Gravellona Toce 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.
“Within 30 km”: epicentres less than 30 km from the centre of Gravellona Toce. “In the town”: quakes whose nearest town to the epicentre is Gravellona Toce.
