"In New England, these tremors occur along a few large faults, or many smaller ones.. Because of local geology, some areas are busier than others. At the busy end of the spectrum are central New Hampshire, central Maine and south-central Connecticut; at the other end are southern Vermont and western Massachusetts."

Yeah I grew up near one of the more active areas in CT, Moodus, a section of East Haddam. Moodus is a local Indian word for ‘Little Noises’. We’d get ~3.0 quakes pretty often, enough to feel, but not do any damage.
