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.

The quake's epicenter was in Hasbrouck Heights, New Jersey. No injuries or structural damage was reported shortly afterward, said Jonathan Tytell, a geophysicist at the USGS.
