A very small earthquake was recorded Tuesday afternoon in Sanbornton, according to the U.S. Geological Society.

No damage was reported in the temblor, which occurred about 4:41 p.m.

The earthquake measured a 1.9 magnitude on the Richter scale, a size that often goes undetected, according to experts. The quake’s epicenter was measured to be about 3 miles west of the town proper. Under USGS standards, a quake twice as strong as that measured Tuesday would be “not felt except by a very few under especially favorable conditions.”

Although strong or even mid-sized earthquakes are extremely rare in New England, which is not located anywhere near a geological fault, small earthquakes – those under magnitude 2 – happen on average more than once a month in Northern New England, according to the USGS.
