A magnitude 2.3 earthquake rattled the town of Greenwood late Thursday night.
The quake struck just under 2 miles west of town about 10:29 p.m. at a depth of 3.3 miles, according to the U.S. Geological Survey.
There were reports on social media of agencies investigating reports of a possible explosion in the area, but there was no immediate confirmation of any damage from the quake.
Thursday night’s quake is at least the 19th recorded so far this year, according to a Maine Geological Survey tally through Sept. 1. Ten of those, all since Aug. 11, were recorded near Jonesboro, ranging in magnitude from 1.7 to 3.
Since 1997, there have been more than 130 recorded earthquakes in the state, according to the agency.
The strongest quake in recent memory occurred on July 14, 2006, when a 3.8 magnitude earthquake shook the ground northwest of Portage, according to the Maine Geological Survey. But Maine has felt the impact of much larger earthquakes that hit as far away as Plattsburg, New York, and Quebec City.
About 900,000 earthquakes below magnitude 2.5 are felt each year across the globe, according to Michigan Technological University.
Greenwood is southwest of Rumford.
