A 2.3-magnitude earthquake Sunday, centered approximately 2 miles north-north east of Antrim, was felt by 33 people over a period of 22 hours, according to the United States Geological Survey’s (USGS) website.

The Category IV quake, considered “light” in terms of shaking according to the USGS, happened at about 2 p.m. with a minimum distance of approximately 32 miles.   

Since 1925, 201 earthquakes have been reported by USGS in New Hampshire. That year, a 4.0 quake occurred near the town of Ossippe and the largest quake in state history measured 5.6 in magnitude near Tamworth in 1940. Earthquakes of this size are considered moderate in terms of shaking and can cause light damage, according to the USGS Earthquakes Hazard Program section on its website, earthquake.usgs.gov.
