Live updates: Earthquake rattles New Jersey, New York and other parts of the Northeast

Flights are now arriving and departing from Newark Liberty International Airport, in the New York City area after being paused due to the Friday morning quake, officials said.

The air traffic control tower was evacuated, and controllers moved to a nearby location. That evacuation and the Port Authority's runway inspections caused flights to be held for a short time earlier in the day.  

The Federal Aviation Administration says flights may be delayed 45 minutes into Newark. The ground stop is holding planes that haven't yet left for Newark from departing.  

Earlier Friday, New York Gov. Kathy Hochul announced the full ground stop at Newark Airport.

Meanwhile, Hochul said Amtrak, the rail company with train service throughout the Northeast, and the MTA, which runs New York's public transportation including the subway system, were both on "full schedule" with "no disruption at this time."

Amtrak had said earlier that it initiated some speed restrictions while it inspected its tracks.

New Jersey Transit, meanwhile, has reported some disruptions.
