A small earthquake was recorded early yesterday in southeastern New Hampshire. The 2.3-magnitude quake was recorded at 9:53 a.m. in Gilmanton, the US Geological Survey said. The quake originated about 7 miles down. Gilmanton is a few miles south of Lake Winnipesaukee. One person reported feeling the earthquake in Wolfeboro, the agency said on its website. A 1.8-magnitude aftershock was recorded at 10:10 a.m., the agency said. Chris Ahern, an emergency medical technician at the Fire Department in Pittsfield, 9 miles from the epicenter, said no one there felt the quake and no residents called about it. Kenneth Erickson, chief of the Laconia Fire Department, 10 miles from the epicenter, also said nobody reported feeling the earthquake. The US Geological Survey says quakes with a magnitude of 2 to 3 produce only weak shaking and no damage.
