Wow crazy! I never even realized they had quakes up this far. From the USGS
"The area around Concord experienced a number of shocks between 1872 and 1891. Two moderate earthquakes, the first on November 18, 1872, and the second on December 19, 1882, were felt at Concord. The first shock, described as lasting only 10 seconds, was felt in adjacent towns and at Laconia, 50 kilometers to the north. The 1882 tremor was strongest at Concord, although buildings reportedly shook at Dover and Pittsfield. The town of Contoocook, near Concord, reported an earthquake of moderate intensity on January 18, 1884. On November 23, 1884, two more earthquakes, the first a light shock, followed 15 minutes later by a heavy one, were felt at Concord. Nearby, at Henniker, the foundation of a boiler was displaced. The second shock was felt over an area of about 20,750 square kilometers including eastern Massachusetts, Connecticut, and eastern New York. Concord again experienced a mild tremor on May 1, 1891. The earthquake was reported felt at Cambridge and Melrose, Massachusetts."
