These were the six earthquakes reported by the USGS on Monday, July 21: Prior to Monday’s earthquakes, New Jersey had only two small tremors reported this year, including a 2.4 magnitude quake that jolted the northern New Jersey region near New York City. That quake was centered about 1 mile east-southeast of Paramus in Bergen County.

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.
