We reported a little earlier that flights had been grounded at JFK Airport in New York and Newark International in New Jersey - but those stops have now been lifted.

All air traffic operations have resumed, the FAA says.

Today's 4.8 magnitude earthquake impacted facilities in New York, New Jersey, Philadelphia and Baltimore.

Allison Martins told the BBC that she was making "a little video on the day in the life of somebody who works from nine to five" when the earthquake struck.

"We're not used to having earthquakes in New Jersey, let alone a big one like this; we were all scared," she said.

We also heard from from New York's buildings commissioner James Oddo, who says the team's construction enforcement unit is out doing inspections, similar to what they do after big storms.

He says there are 1.1 million buildings in the city.

"The Department of Buildings have not seen an influx of calls regarding building damage," he says.

The department is concerned about some downstream possibilities, such as cracks that may show up in a week or later, as well as wall damage, he says.

The mayor's press conference has now wrapped up.

Stick with us, next up we will check in with some more locals about their experiences.

Zachary Iscol, the commissioner of NYC emergency management, spoke after Mayor Adams.

He says the likelihood of aftershocks is "low" but officials are still asking that if they do occur - anyone outside should go to an open space, "away from buildings and trees".

Next up, Chancellor David C Banks gives some information on New York's public schools. He says there are no reports of staff or students being injured at any school in the New York area. As such, headteachers have been told to carry on as normal.

"Parents do not need to pick up their child early because of today's earthquake," he says, praising the professionalism of school staff, adding "all of our students across the school system are safe, all of our staff are safe".

We're hearing from New York Mayor Eric Adams now, who says New Yorkers should go about their normal day.

"First responders are working to make sure the city is safe," he says.

We've just heard from NY Governor Kathy Hochul - and soon it'll be the turn of Mayor Eric Adams to address reporters and New York City residents.

In a pre-statement, he says the earthquake took place at 10:23 ET (15:23 GMT) - and the city's first responders "are working to make sure New Yorkers are safe, and at this point, we do not have any reports of major impacts or injuries".

Giving some safety advice, he goes on: “I encourage all New Yorkers to check on your loved ones, and if you feel an aftershock, drop to the floor, cover your head and neck, and take cover under a solid piece of furniture, next to an interior wall, or in a doorway."

Mayor Adams says "inspections of critical infrastructure" are under way.

The BBC's North American correspondent John Sudworth, who is in Manhattan, has been explaining what the earthquake today felt like.

He says he felt the building he was in shake for "15 or 20 seconds or so".

Watch what else he says below:

We're hearing from more New York officials now, including New York State Division of Homeland Security and Emergency Services Commissioner Jackie Bray, who says there was overloading on cell networks during the earthquake.

She says the state is in touch with hospitals to monitor for injuries related to the incident.

That's a wrap from the governor's update, but the mayor of New York is expected to speak to media very soon. We'll have a live stream of that at the top of this page, which you can watch by pressing the play button.

New York Governor Kathy Hochul has stressed the seriousness of today's quake.

But "no life-threatening situations" have been identified yet, she says, adding that her team was reviewing the state's infrastructure.

Hochul is advising New York residents how to act if there is an aftershock.

"Drop to the floor", she says, and hold onto something sturdy.

She also says residents should stay away from high rises, and if they hear shifting or unusual noises, they should leave their home.

Check water and gas lines to make sure your family is safe, she adds.

New York Governor Kathy Hochul confirms that JFK Airport in New York and Newark International in New Jersey are under full ground stops right now, as authorities wait for any potential aftershocks.

We're hearing from New York Governor Kathy Hochul now.

She says the state is taking the earthquake very seriously because of potential aftershocks.

While we are waiting for an update from the New York governor, let's look at how the strength of earthquakes are measured.

There are differing methods of calculating an earthquake's power, usually measured out of 10 on what are known as seismic magnitude scales.

The BBC is reporting it as reaching a magnitude of 4.8, the calculation given by the US Geological Survey.

It's the biggest earthquake the New York area has experienced for 40 years.

Anything above 7 is considered a major earthquake, so this is some way off that.

One thing to note is these measures are often incorrectly described as being on the "RichterScale" - an earlier method of describing the size of earthquakes that has since largely been updated and replaced by scientists.

We are about to hear from Kathy Hochul, the governor of New York.

We'll bring you the latest updates from her briefing.

Stay with us.

New Yorkers are used to wild weather and major storms, but they're not so used to earthquakes.

A 3.8-magnitude earthquake did strike Buffalo, New York last year on 6 February, but an earthquake of today's size has not occurred in the area for 40 years.

That quake, in 1983, shook residents near the town of Newcomb, in upstate New York with a 5.1 magnitude.

We're beginning to hear from various officials in New York, including Deputy Mayor Fabien Levy who says New York City felt the impacts of an earthquake "with an epicentre of Lebanon, New Jersey".

He adds that the mayor, Eric Adams, is being briefed.

"While we do not have any reports of major impacts at this time, we’re still assessing the impact," the post on X says.

Meanwhile, Governor Kathy Hochul says the effects were felt throughout New York, and her team "is assessing impacts and any damage that may have occurred, and we will update the public throughout the day".

Mayor Adams is expected to give an update at 12:00 local time.

Several of New York's airports have paused operations due to the earthquake.

Both John F. Kennedy International Airport and Newark Airport in New Jersey have ground stops in effect.

There are also delays at New York's LaGuardia Airport.

The pauses are likely so crews can assess damage to the airport and runways and make sure there is no debris.
