RINGWOOD - A small earthquake rattled part of Passaic County early Saturday morning.

The U.S. Geological Survey confirms that a 2.1-magnitude earthquake struck just before 1 a.m. and was centered near Ringwood.

There were no reports of any damage or injuries.

Earthquakes happen in the area from time to time, experts say, because Ringwood sits on the Ramapo fault line.

“The fault line is very old, it is not known to make major earthquakes, but it produces small ones on a regular basis," says Vadim Levin, an earthquake seismologist at Rutgers University.

Levin added that the quakes are mild and the people of Ringwood do not need to worry.

It is advised, however, that people report the next time they feel the rumblings of a quake.

Levin says the USGS has a site for reporting called, "Did You Feel It?" that allows scientists to see where and how often the quakes hit.

While Ringwood was the epicenter, News 12 viewers say they felt the quake in Pompton Lakes, Kinnelon and Cliffside Park.
