USGS reports 3.8 magnitude earthquake off coast of York, Maine

YORK, Maine — The U.S. Geological Survey is reporting a magnitude 3.8 earthquake happened off the coast of southern Maine on Monday.

According to the USGS, the earthquake happened at 10:22 a.m. just over 6.2 miles (10 km) southeast of York Harbor. The depth of the earthquake was 8.2 miles (13.2 km).

The Maine Geological Survey's online database indicates that this earthquake was tied for the third-strongest earthquake with an epicenter in Maine since 1997. The only earthquakes that were stronger were a magnitude 4.5 that happened in East Waterboro on Oct. 16, 2012, and a magnitude 4.2 that happened east of Cadillac Mountain in Acadia National Park on Oct. 2, 2006. A magnitude 3.8 earthquake last happened on July 14, 2006, about 15 miles northwest of Portage in Aroostook County.

Maine's Total Coverage has received reports from people across southern Maine who felt the ground shake or heard a loud rumble. People in New Hampshire and Massachusetts also reported feeling the earthquake.

The state of Maine typically experiences several small earthquakes every year.

In 2024, there were four earthquakes with an epicenter in Maine. The strongest was of those earthquakes came on July 28, when a magnitude 2.8 happened in West Gardiner.

The Richter Scale is logarithmic, which means each whole number increase in magnitude represents a tenfold increase in scope. Therefore, Monday's earthquake had a ground motion 10 times as large as the one that happened in West Gardiner on July 28, 2024.
