Earthquake in Maine Rattles New England States

The earthquake that rattled southern Maine was felt in New England states as far away as Connecticut, but caused no apparent damage or injuries.

Patrons of a pizza parlor near the epicenter of Tuesday’s quake didn’t know what was going on when the building started shaking, but it was enough to send all 20 of them hustling outside.

“It was loudest bang you ever heard in your life. We actually thought it was an explosion of some type,” said Jessica Hill, owner of Waterboro House of Pizza. “The back door and door to the basement blew open,” she said.

The U.S. Geological Survey said the 4.0 magnitude quake hit around 7:12 p.m. and its epicenter, about 3 miles (5 kilometers) west of Hollis Center, Maine, was about 3 miles (5 kilometers) deep. That location is about 20 miles (32 kilometers) west of Portland. The quake was first estimated to be 4.6 magnitude but was later downgraded.

In Saco, Sue Hadiaris said, “The whole house shook. …It was very unnerving because you could feel the floor shaking. There was a queasy feeling.”

Afterward, Hadiaris called her 15-year-old niece in Falmouth to make sure she was safe. “She said, ‘We can cross that off our bucket list. We’ve lived through an earthquake,”‘ Hadiaris said.

Earthquakes are rare in New England but they’re not unheard of.

The strongest earthquake recorded in Maine occurred in 1904 in the Eastport area, near the state’s eastern border with Canada according to the Weston Observatory at Boston College. It had an estimated magnitude of 5.7 to 5.9.

Tuesday’s quake was the most powerful tremor in New England since Oct. 2, 2006, when a 4.2 magnitude quake struck Maine’s Mount Desert Island, causing boulders to tumble onto Acadia National Park’s Park Loop Road, said Weston Observatory Director John Ebel. The 2006 quake was one of a string of tremors and aftershocks that rocked Mount Desert Island over several months, but there’s no evidence to suggest that there’ll be an active sequence of aftershocks following the latest earthquake, Ebel said.

The Seabrook Station nuclear plant, about 63 miles (101 kilometers) away in New Hampshire, declared an unusual event – the lowest of four emergency classifications – but said it was not affected. The plant has been offline for refueling.

“There has been no impact at all to the plant from the earthquake and our refueling maintenance activities have not been affected,” said Alan Griffith, spokesman for Next EnergyEra Seabrook Station.

Jim Van Dongen, public information officer for the New Hampshire Department of Safety said New Hampshire emergency services got about 1,000 calls in the first hour after the quake, but they later dropped off. He said no major damage was reported.

Brief, but noticeable shaking was felt in downtown Boston and the surrounding area.

Edward Conti, who lives in a four-story apartment building in Cambridge, Massachusetts, he was watching television when “it sounded like a car crash. Then there was another boom-boom. It was no small thing.” Conti said there was no damage.

In Melrose, just north of Boston, Peter Ward said the shaking he felt seemed to last about four seconds. “It felt like a big gust of wind shaking the house. I don’t want to overstate it, but the glass did rattle a little,” he said.

Lynette Miller, a spokeswoman for the Maine Emergency Management Agency, said her dogs started barking several seconds before the quake on Tuesday. “It was several seconds of good shaking but nothing falling down,” Miller said from her home in Readfield, about 60 miles north of Portland.

In Portland, Abbie Miller had just turned on the aging furnace in her house for the first time this season. “An hour later, things started shaking and it sounded almost like a train coming through. I thought my furnace was going to blow,” she said.

East Coast quakes are rarely strong enough to be felt over a wide area. A quake of magnitude 5.8 on Aug. 23, 2011, was centered in Virginia and felt all along the coast, including in New York City and Boston. Experts say the region’s geology can make the effects felt in an area up to 10 times larger than quakes of similar size on the West Coast.
