A moderate earthquake rattled much of eastern Maine Monday night with tremors felt at least as far away as Mechanic Falls.

The quake caused some rocks to fall onto a road in Arcadia National Park and burst some water pipes. No injuries were reported, authorities said.

The quake, initially calculated at magnitude 3.4 on the Richter Scale, appeared to be centered in Great Head near Bar Harbor, according to the U.S. Geological Survey.

Jeff Chamberlain, dispatcher for the Bar Harbor Police Department, said the quake was measured at a magnitude of 4.2.

“We had clothes, towels, hanging on the bathroom door and they were swaying back and forth,” said Maureen Campbell of Mechanic Falls. She said her husband, James, also felt a swaying sensation.

Closer to the epicenter, things were rocking a bit more.

“The glasses were shaking – it was scary,” said Dee Beaudoin, 53, a bartender at Geddy’s restaurant and pub on Main Street in Bar Harbor. “My worst thought was, ‘Oh no, glass in the ice!'”

“Everybody kind of looked around and looked at each other,” Beaudoin said. “It felt different from the others.”

The USGS said the earthquake was recorded at 8:07:37 p.m. The agency said the earthquake appeared to be about 5 kilometers or about 3 miles deep.

The epicenter was roughly 45 miles southeast of Bangor, 80 miles of Augusta, and 70 miles southwest of Eastport.

A 3.5 earthquake occurred a week ago Friday and another measured at 1.8 occurred just this past Thursday, Beaudoin said, adding that people are speculating that this one measured 3.5 to 4.0.

“We’ve been having aftershocks, but this one had more of an impact than the others we’ve had,” she said. “It’s been an experience. I do not like them.”

A magnitude 3 earthquake can be felt and sometimes rattles dishes and windows but generally cause little if any damage, according to the USGS.

Monday’s quake was the third to hit Maine in recent weeks.

Mount Desert Island residents awoke to the earth moving Friday, Sept. 22, and the shaking didn’t stop until several hours later.

Monitors recorded five hours of earthquake activity, with the biggest being a magnitude 3.5 quake at 6:39 a.m. about one mile southwest of the middle of Bar Harbor, said John Ebel, director of Massachusetts’ Weston Observatory.

There were roughly nine additional temblors starting at 5:21 a.m. before the main quake and continuing through 10:20 a.m., Ebel said of the Sept. 22 event.

A 2.5 magnitude quake followed on Thursday, Sept. 28, the USGS said on its Web site.

New England averages one or two earthquakes above 3.5 magnitude each year. Maine recorded a 3.8-magnitude earthquake in the northern part of the state on July 14.
