Residents along the Connecticut and Ammonoosuc Rivers say they felt their homes shake after an earthquake just after 5 p.m., centered near Woodsville.

The New England Seismic Network at the Weston Observatory of Boston College reports quake measured 2.6 at 5:09 p.m. It was located about 4 miles south of Woodsville.

The social media site Facebook rocked with residents from Woodsville through Bath, Landaff and Lisbon reporting that they felt their houses shake for several seconds and that they could hear a loud bang. Some said they thought there had been an explosion nearby.

Sheila Brill of Woodsville, not far from the epicenter, said she was opening a door and heard a loud bang and then house shook.

"I thought at first my furnace had malfunctioned," she said. "I didn't know whether to stay inside or go outside, so I stayed inside just long enough to pour a glass of wine, which I took outside."

Emergency dispatchers at the Grafton County Sheriff's Department said there have been no reports of injury or damage.
