The ground in parts of Morris County was doing a lot of shaking on Monday, with six small earthquakes reported by residents at various times from the early morning to late-night hours. That’s the latest word from the U.

The U.S. Geological Survey reported the quake, which hit at about 5:40 a.m. with an epicenter slightly west of Morris Plains in Morris County, at about 1.6 in magnitude. Earthquakes of that magnitude are considered to be minor, and don’t usually result in damage.
