A mild earthquake rattled Addison County at approximately 2:20 a.m. October 10, 2002. The 2.8 magnitude tremblor was centered two miles south of Middlebury near Route 7 at a depth of five miles inside the ancient basement rocks of Grenville. There were no reports of damage to structures or other property. According to Won-Young Kim of the Lamont-Doherty Earth Observatory of Columbia University in Palisades, NY, this earthquake may be connected to an old chain of Atlantic volcanoes. Earthquakes with epicenters in New England may be distantly linked to a zone of more than 30 drowned “hot spot” volcanic mountains — called seamounts — located off the coast of Cape Cod. These prehistoric mountains formed a chain of Hawaiian-like islands. “The volcanoes are extinct now, but the old fault zone — that runs from the Atlantic up into Canada — can still have tectonic movement,” Kim said.
