The U.S. Geological Survey's website says a 2.1-magnitude earthquake briefly shook Rockaway Borough on Sunday. Officials say the quake hit at 11:54 a.m.
Some residents in the Morris County community say they felt the quake in their homes. But for most, the event was over before most realized what was happening.
While earthquakes in New Jersey are rare, Rockaway experienced several small ones last summer.
