An earthquake was detected off the coast of New Hampshire early Wednesday, the second quake to occur in the area this week, the U.S. Geological Survey reported.

The 3.8-magnitude earthquake was centered around 10 miles east of Portsmouth, in an area in the Atlantic Ocean just north of the Isles of Shoals. Video from the Shoals Marine Laboratory on Appledore Island shows the camera shaking when the earthquake hit at around 10:22 a.m.

Experts from UNH explain how rare the 3.8 magnitude earthquake was and the likelihood of significant aftershocks.

A 3.8 magnitude earthquake is on the smaller end of the Richter scale and even for people who may have felt it here in Massachusetts. It’s not likely that there was any damage.
