The chief executive of the nonprofit organization Save The Children was briefing an emergency Security Council session this morning on Gaza when things at the meeting got shaky — literally.

As Janti Soeripto spoke, meeting attendees looked around the room and at each other. Today's earthquake was making the room at the United Nations headquarters in New York City shake.

Soeripto paused.

"Is that an earthquake?" she asked.

"You're making the ground shake!" someone quipped back.

More earthquakes could hit the New Jersey area in the coming weeks, according to the U.S. Geological Survey. 

Sara McBride, a research social scientist with the USGS, said that at least two aftershocks have been reported so far following this morning’s magnitude-4.8 quake. She said USGS researchers’ aftershock forecasts suggests there is a small chance of an even stronger earthquake in the coming weeks. 

“There’s a 3% chance for one or four aftershocks larger than a magnitude-5 in the coming weeks. A larger than magnitude-5 can be damaging,” McBride said. 

She explained that the aftershock forecast is calculated using statistical data from thousands of past earthquakes of similar size. It’s a generic model, and not specific to the New Jersey region. 

Jessica Jobe, a USGS research geologist, said there have been at least three magnitude-5 earthquakes in the region since the 1700s. 

“This is a region with many older faults that may be reactivated at any time at this time. The fault that causes the earthquake isn’t yet known,” she said. 

The New Jersey county where the earthquake struck this morning has sustained some structural damage to private property but has received no reports of injuries so far, according to officials.

The magnitude-4.8 earthquake struck near Lebanon shortly before 10:30 a.m. ET and was followed by two aftershocks, Brayden Fahey, Hunterdon County’s Office of Emergency Management coordinator, said at a news conference.

Authorities are assessing the damage and do not yet have a sense of how many properties may have been affected. But there have not been reports of any issues with gas or other utility lines, officials said.

"I think all of us collectively were jarred by what we experienced," Fahey said. “All of us probably feel very fortunate that there’s not more damage and more issues facing us."

Shortly after the earthquake, Faces Of Haiti, a social media account for Haitian people, posted that the tremors might “bring severe PTSD in the following days” for those who experienced the devastatingly deadly quake in 2010. “Keep checking on your loved ones’ mental health in the Tri-State area, even when they say they are ok.”

Almost immediately, followers shared their experiences this morning as the earthquake rippled down the East Coast. 

“Thank you for this. I was the first in my workplace to understand what was happening, and I’m the last one to be over it,” one person wrote in a comment on the post. “Still shaking typing this.”

"you and I both," another user responded. "I screamed right away, ‘It’s an earthquake, it’s an earthquake, guys,’ and my coworkers were calm about it and didn’t say anything. My heart was racing, and I was thinking about the nearest exit. Nahhhhh. We don’t play that over here. I had enough in 2010. Whatever the magnitude is, I’m traumatized for life.”

“Thank you for acknowledging and sharing this message," one person wrote. "Haiti was the first image in my mind once I realized what I was experiencing as everything around me was shaking/rattling.”

“My sisters called me crying and scared,” said another.

In 2010, a 7.0-magnitude earthquake struck Haiti, leaving its capital, Port-au-Prince, in ruins. An estimated 220,000 people were killed, some 300,000 people were injured, and 1.3 million lost their homes during the 35-second temblor.

The earth shook for a second time this morning.

Though it was subtle, a second earthquake hit the New Jersey area at about 11:20 a.m., according to U.S. Geological Survey data.

The aftershock registered as a magnitude 2.0. It was roughly 4 miles west of Bedminster, New Jersey.

There have been no major damage or injuries reported in the state in today's earthquake, Connecticut emergency officials said during a news conference this afternoon.

However, officials are still working with state agencies to ensure there are no threats to buildings or critical infrastructure. Deputy Commissioner Brenda Bergeron said that the state's Transportation Department is also doing visual inspections of bridges and critical infrastructure critical bridge infrastructure "in an abundance of caution."

"We are not seeing any significant damage but we are in partial activation and continuing to work with our state local, federal and private sector partners on making sure that everyone is safe and sound," Bergeron said.

No power outages or damage have been detected in connection with today’s quake, according to PSE&G, the energy utility that serves New Jersey.

The company said it completed initial system inspections of its electric infrastructure.

“As part of our earthquake response protocol, we are currently performing a strategic system check of our electric and natural gas infrastructure near the epicenter, Tewksbury,” PSE&G said. “The safety of our customers and employees is the number one priority.”

A 4.8-magnitude earthquake on the Atlantic coast is "a little unusual, but it happens from time to time," science educator Bill Nye told MSNBC.

"It just shows you everybody the importance of being prepared," he said.

Nye encouraged people to secure their cabinet doors and keep flashlights, food and water on hand in case of an electricity outage.

All NYC Health + Hospitals facilities are operating normally, the system said in a post on X.

"All our patients & staff are safe, and we are not seeing an increase in volume at our emergency departments," the hospital added in the post.
