An unexpected magnitude 3.8 earthquake off the coast of Maine caused a stir in parts of the Northeast on Monday morning. The quake, which occurred about 6.5 miles southeast of York, Maine, just before 10:30 a.m., was initially reported as a 4.1 by the U.S. Geological Survey (USGS) before being adjusted to 3.8.
The USGS noted that earthquakes along the Atlantic Seaboard are uncommon but not unheard of, as demonstrated by today's event near Bar Harbor, Maine. Fortunately, the National Weather Service (NWS) in Caribou, Maine, confirmed that there was no risk of a tsunami following the quake.
