YORK HARBOR, Maine - Another earthquake has been recorded off the coast of Maine, an aftershock from a larger quake that shook Boston, New Hampshire and Rhode Island two days earlier.

The magnitude 2.0 earthquake was detected at 3:15 a.m. Wednesday about six miles southeast of York Harbor, Maine, according to the United States Geological Survey. The epicenter was almost the exact same location as the 3.8 magnitude earthquake that was felt in Boston and hundreds of miles away throughout New England on Monday.

"We had a little aftershock this morning," scientist John Ebel with the Weston Observatory at Boston College told WBZ-TV.

Like Monday, there were no reports of damage or injuries from the earthquake that happened. six miles underground.

Aftershock not widely felt

Wednesday's earthquake was not widely felt. Only about 20 people from the York area filed "Did You Feel It" reports with the USGS on Wednesday, compared to more than 40,000 who shared their experience from the earthquake on Monday.

Earthquake aftershocks

An earthquake like the one earlier in the week happens once every four or five years, Ebel told WBZ-TV.

He said it's no surprise that New England is seeing aftershocks.

"This is very typical, an aftershock two days later," Ebel said, adding that they could keep happening for a week or more after the initial earthquake.

"And it's even possible that there will be a larger aftershock," he said. "Might be a 2.7, 2.9, even a 3.0"
