A small earthquake rattled parts of central New Jersey.

The U.S. Geological Survey says the magnitude-2.7 quake hit around 3:41 a.m. Friday, roughly 2 miles north of Bernardsville at a depth of 3 1/2 miles. It was initially reported as a 2.5 magnitude.

Police say there are no reports of damage or injuries.

USGS geophysicist Zachary Reeves says 78 people reported feeling it.

Reeves says such small earthquakes usually don't cause damage, but people will usually feel a little bit of shaking on higher floors.

The USGS says smaller earthquakes are felt in the region every two to three years.

The last earthquake reported in New Jersey had a magnitude of 1.9 and happened about 17 miles east of Trenton on Dec. 13, 2014.
