HARRISON — An earthquake has been recorded in Maine, the fifth in a week.

The U.S. Geological Survey on Wednesday confirmed a magnitude 2.3 earthquake struck around 2 a.m. The earthquake was centered near Harrison, and several people said they felt it.

There was no reported damage or injury.

“We did not get any calls on it,” Harrison Fire Chief Dana Laplante said. “We all learned about it on Facebook this morning, to be honest with you. We were just surprised more than anything else.”

On the Friends of Harrison Facebook page, dozens of people reported hearing and feeling a rumbling around 2 a.m. Some thought it was ice sliding off their roofs, others believed it was a falling tree, passing traffic or a generator blowing up.

“I felt a serious vibration,” wrote Julie Mannix, who lives on School Street, in the village. “I dismissed it, thinking it was a town plow truck hitting the pavement hard.”

Another minor earthquake was recorded near Richmond on Jan. 17. The agency says that 2.6 magnitude quake struck before 7 p.m., and it was followed by two other minor quakes.

Fairfield was shaken by an earthquake two days after that, a magnitude 1.7.

Earthquakes occur in New England, but they’re relatively rare.

A 4.0 magnitude quake in 2012 near Hollis was felt as far away as Connecticut, and a 4.2 magnitude quake in 2006 struck Maine’s Mount Desert Island, causing boulders to tumble.
