Small earthquake felt in Souhegan Valley

A small earthquake measured at 2.1 on the Richter scale was felt in the Souhegan Valley early Friday morning.

The tremor was recorded at 1:45 a.m. Friday just north of the town of Milford. No damage was reported but many people online said it woke them up. As of mid-morning, 135 people had responded to the “Did you feel it?” section of the USGS Earthquakes Hazard website, saying they felt or heard the quake.

The U.S. Geological Survey says the quake originated about five miles underground, a typical depth for earthquakes in New Hampshire.

New Hampshire gets one or two small earthquakes in a year, but has not been hit by a major quake in hundreds of years. That’s because we’re the interior of the North American tectonic plate and most earthquakes happen at the edges of these massive plates, which carry the planet’s continents as they float around the globe on underlying layers of hot magma.
