A magnitude 4.0 earthquake struck southern Maine shortly after 7 p.m. ET and was felt in Boston.
The U.S. Geological Survey says the quake, about 17 miles deep, was centered near Lake Arrowhead.
No reports so far of any damage.
The USGS says the New England region has "felt small earthquakes and suffered damage from infrequent larger ones since colonial times. Moderately damaging earthquakes strike somewhere in the region every few decades, and smaller earthquakes are felt roughly twice a year."
