A 2.5-magnitude earthquake rattled parts of New Jersey Friday morning, according to the U.S. Geological Survey.
The USGS said the quake struck at 3:41 a.m. just north of Bernardsville.
Bernardsville Police say there have been no reports of damage or injuries.
USGS geophysicist Zachary Reeves says 78 people reported feeling it. Observers on social media also reported feeling the rumble as far away as Rockland County in New York.
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 was about 17 miles outside of Trenton on Dec. 13, 2014.
