A magnitude 3.0 earthquake centered in New Jersey briefly shook NYC Saturday night, prompting emergency guidance but no major damage.

If the earthquake triggered memories of last year's big shake there are some key differences. Last year's earthquake centered near Tewksbury, New Jersey, was a magnitude 4.8. That's almost 20 times stronger than Saturday night's earthquake.

A small earthquake rattled some parts of the New York City area Saturday night, according to the U.S. Geological Survey. The epicenter of the 3.0 magnitude quake was northeast of Hasbrouck Heights, New Jersey, in Bergen County, about 10 kilometers below the surface, USGS said.
