Typically, earthquakes with magnitudes under 2.0, which are classified as “micro” earthquakes, are not felt on the surface. Earthquakes with a magnitude between 2.0 and 2.9 are referred to as "minor" earthquakes and are more likely to be felt by people. Several residents have reported feeling the geological phenomena, as well as the aftershocks they cause.
“The noises and shaking continues. It is very unsettling,” one resident wrote on Nextdoor Monday afternoon. “Here are the times 5:45 a.m., 6 a.m. 6:15 a.m. 1:30 p.m…. 2 hard slams that shook (the) house (at) 3:35 p.m., 3:39 p.m. Is any town or county agency looking into this?”
As the evening stretched on, multiple Randolph residents reported on social media loud “booms” that frightened them, their spouses, and pets. The posts tapered off around 10 p.m.
"The U.S. Geological Survey has confirmed a series of two minor earthquakes occurred yesterday near the southeastern section of Randolph Township," Randolph Mayor Joe Hathaway said in a statement. "We want to reassure our residents that no damage to infrastructure or property, or bodily injury has been reported as a result of these tremors. We are in touch with the State of New Jersey on the situation and will continue to prioritize the safety and well-being of the Randolph community."
The Morris County Office of Emergency Management has posted regarding the incidents, citing that no damage has been reported as a result of the quakes.
Aftershocks follow the mainshock, and are “part of the ‘readjustment process’ after the main slip on the fault,” according to the U.S. Geological Survey.
Experts also said that aftershocks, while typically brief, can occur days, weeks, months, and even years after the mainshock.
Nearly 60 NJ residents reported to the U.S. Geological Survey that they felt Monday morning’s earthquake, and just over 50 reported feeling the Monday evening tremor.
