NEW YORK - A strong earthquake sent shockwaves throughout New York City and the surrounding area Friday morning. 

The 4.8 quake was centered in Readington Township, New Jersey, 40 miles west of New York City, according to the U.S. Geological Survey. It hit at approximately 10:23 a.m. 

The impact was felt throughout the Tri-State Area, including upstate in Syracuse, as well as in Philadelphia and as far away as Baltimore. The USGS said it was felt all the way from Maine to Washington, D.C.

Reports of buildings shaking and rattling came in from New Jersey to Long Island at the time of impact. 

A 2.0 aftershock struck west of Bedminster, N.J. about an hour later.

"We're taking this extremely seriously and here's why. There's always the possibility of aftershocks. We have not felt a magnitude of this earthquake since about 2011," New York Gov. Kathy Hochul said. "This is one of the largest earthquakes on the East Coast to occur in the last century." 

Hochul said she has started a damage assessment across the state, and spoke with New Jersey Gov. Phil Murphy, since the quake's epicenter was located in the Garden State. 

"It's been an unsettling day, to say the least," Hochul said.

Murphy, who was at a conference out of state when the quake hit, touted the response locally. 

"The reaction was swift and very impressive by the likes of the Port Authority, our State Police opening up its emergency operations center, local and county officials," Murphy said. 

He said the top infrastructure concern is the Hudson River tunnels, though so far there were no reports of major damage. 

"The rail tunnels were built in, finished in 1911, which is why we're building two new ones," Murphy said. 

NYC Mayor Adams: "New Yorkers should go about their normal day"

New York City officials said there have so far been no reports of major impacts across the city. 

New York City Mayor Eric Adams said though there's always a concern about aftershocks, "New Yorkers should go about their normal day. First responders are working to make sure the city's safe."

In the event of an aftershock, Adams said people should "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." 

Adams also said he's been in touch with the White House. 

"Earthquakes don't happen every day in New York, so this can be extremely traumatic - the number of texts, calls and inquiries that people sent out not only to our administration, but to family members. Check in on them. We know how this can impact you," Adams said. 

New York City public schools were told to continue operations and hold dismissal as normal.

"Parents do not need to pick up their child early as a result of today's earthquake. Additionally, all after-school programs will continue as planned," New York City Schools Chancellor David Banks said. "All of our students across the school system are safe. All of our staff are safe. We have no reports of any structural damage to any of our school facilities, while many schools in fact felt some tremors from the earthquake." 

Adams said he was at a Youth Gun Summit at Gracie Mansion and did not feel the quake himself. 

Traffic, transit and airport impacts of the quake

The quake caused temporary ground stops at John F. Kennedy and Newark Liberty airports. There were delays as well as LaGuardia as crews checked for damage to the airports and runways

The MTA said it is inspecting all New York City-area bridges and tunnels. Officials also said subway tunnels were checked. 

"Initial inspections show there was not damage to any MTA infrastructure, but we will continue to monitor the situation closely," the MTA posted on X. 

Amtrak and MTA service remained on their full schedule, Hochul said. 

"I was laying in my bed, and my whole apartment building started shaking. I started freaking out," one New York City resident told CBS New York's Elijah Westbrook. 

Cracks in walls were visible in an apartment in Berkeley Heights, N.J. 

The Empire State Building had bit of fun after the quake. 

"I AM FINE," the building posted on X. 

More history of earthquakes in New York

When was the last earthquake in New York City? 02:27

It's not the first time the East Coast and New York City have been hit with a quake. A 5.0 quake was measured in New York City in 1884. 

There's a major fault line in New Jersey called the Ramapo Fault, which stems from the Appalachian mountains, and there are at least five smaller fault lines under Manhattan island. 

The quake comes just a few months after the USGS warned nearly 75% of the United States could face damaging quakes in the next 100 years

In 2011, a 5.8 quake struck in Virginia and rattled the entire East Coast.
