BAR HARBOR (AP) – Another earthquake shook Mount Desert Island on Friday, continuing the string of quakes and aftershocks that have been felt since late September.

Friday’s rumbling was felt at around 4:20 p.m. and prompted about a dozen phone calls to Bar Harbor police, but no damages or injuries were reported.

The latest tremor had a magnitude of 3.5 and was centered in Frenchman Bay just east of Hulls Cove, according to the Weston Observatory at Boston College, which tracks seismic activity in the Northeast.

The quake was the second-strongest since the earthquakes and aftershocks began in the Mount Desert Island area on Sept. 22. Besides being felt in Bar Harbor and neighboring towns, the quake was reported being felt as far away as Lincoln and Waterville, which are more than 65 miles from Bar Harbor, according to the Weston Observatory.

The strongest quake since September came on Oct. 2 and had a magnitude of 4.2. It was felt in much of eastern Maine and caused boulders to fall from ledges onto Acadia National Park’s loop road.

Adam VanWhy, a Bar Harbor police dispatcher, said he felt the shaking on Friday and then received calls from residents asking if another quake had occurred.

“I guess people are starting to get used to them,” VanWhy said.

Earthquake experts have warned that aftershocks could be expected for days or weeks after the initial earthquakes. Before Friday, the last tremor in Bar Harbor was recorded on Dec. 18.

After the quakes began in September, scientists from the Lamont-Doherty Earth Observatory at Columbia University came to Mount Desert Island to install temporary earthquake-monitoring stations around Bar Harbor in an effort to learn more about the seismic activity.
