Earthquake off the coast of Maine rattles New England

An earthquake off the coast of Maine shook the region Monday, generating light to moderate shaking across the state as well as sections of Rhode Island, Massachusetts, New Hampshire, and Connecticut.

The United States Geological Survey reported a 3.8-magnitude earthquake that happened soon before 10:30 a.m. ET. The epicenter was located off the shore of York Harbor, Maine, approximately 45 miles southwest of Portland.

Officials say the tremor was felt throughout New England and as far north as Pennsylvania. Many locals in southern Maine reported feeling houses and buildings shake as the unexpected earthquake struck on a beautiful winter morning.

The earthquake was more than eight miles deep, according to the USGS. The National Tsunami Warning Center in the United States declared that there was no tsunami threat to New England.

According to the USGS projection, there is a 15% probability of at least one aftershock of magnitude 3 or higher during the next week.

The quake was the biggest recorded in the northeastern United States since April, when a 4.8-magnitude earthquake occurred in Lebanon, New Jersey. According to USGS data, the shaking was the most violent in the Northeast in over a decade.
