A 2.5 magnitude earthquake was reported off the coast of Maine early Tuesday.

The earthquake was recorded shortly before 4 a.m. about 2.5 miles southwest of Vinalhaven in Penobscot Bay, according to the U.S. Geological Survey. The preliminary depth of the earthquake was about 6.3 miles, the USGS said.

Tuesday’s earthquake was fairly minor. Quakes between 2.5 and 3 magnitude are usually the smallest felt by people, while damage typically does not occur until the magnitude tops 4 or 5.

According to the USGS’ “Did You Feel It?” tool, people reported feeling the earthquake as far away as Bucksport, Castine and Union.

It is not unusual for Maine to experience minor earthquakes that go largely unnoticed, but the fifth largest in Maine history happened earlier this year.

The magnitude 3.8 earthquake on Jan. 27 was centered 6.2 miles southeast of York Harbor but was felt as far north as Bangor and as far south as New York City. During that event, people across southern Maine reported shaking that lasted 20 to 25 seconds; some people mistook the sound for an explosion.

That earthquake was followed by a couple of aftershocks with magnitudes around 2.0.

A few weeks later, a 2.5 magnitude earthquake was recorded about 21 miles northwest of Millinocket.

The largest earthquake recorded in Maine was a magnitude 5.7 that occurred near the Canadian border in 1904.

The last earthquake centered in Maine with a magnitude of 4.0 or greater was in October 2012. That magnitude 4.7 earthquake, with an epicenter in York County, was felt as far away as Connecticut and prompted concerned residents to overwhelm local 911 centers.
