The New York Times reports:
Aftershocks continued throughout the day Friday, including one that measured 4.0 just before 6 p.m. and that was felt widely across New York and Jersey. Aftershocks would likely “continue for several days and even a week,” said Kishor S. Jaiswal, a research structural engineer with the United States Geological Survey. There is also a small chance that an earthquake of similar or even larger magnitude could occur during such a sequence, he said.
The earthquakes also revealed apparent shortcomings in New York’s emergency notification system, coming after the Adams administration has been criticized for a delayed response to floods and wildfire smoke. On Friday, beeping text alerts warning residents to stay indoors were received a half-hour or more after the earthquake hit. (In earthquake-prone areas like California and Japan, a network of seismic sensors detect shaking, so alerts can arrive seconds before the quake.)

According to the @USGS, aftershocks could still be felt in the next week. A 50% probability of magnitude 3+, a 15% chance of quakes of magnitude 4+, & 3% a chance exists for an earthquake of similar or larger magnitude.

Did you feel that aftershock?@johndavittontv says while 11 aftershocks have rattled New York City so far, the most recent one was the strongest – a 4.0-magnitude aftershock around 6 p.m. It follows the 4.8-magnitude earthquake felt at 10:23 a.m. pic.twitter.com/ximhoXmCFQ
