Strongest New Jersey quake in 240 years felt across New York City, Northeast

BRIDGEWATER, N.J. – The strongest earthquake to hit New Jersey in 240 years sent shockwaves throughout much of the Northeast Friday morning, with nearly 180,000 reports of shaking felt across New York City and stretching from Maryland to Maine.

The U.S. Geological Survey recorded a preliminary magnitude 4.8 earthquake about 8 miles northeast of Bridgewater, New Jersey, at 10:23 a.m. EDT along the Ramapo Fault. At least a dozen aftershocks have been reported from or near the epicenter, with the greatest being a magnitude 3.8 around 6 p.m.

The earthquake was the strongest in New Jersey since 1783 and the strongest felt in the New York City area since 1884, the FOX Forecast Center said.

THESE ARE THE WORLD'S MOST POWERFUL EARTHQUAKES ON RECORD

Buildings throughout New York City were inspected for structural integrity and damage. Thankfully, there are no reports of major damage or injuries.

However, people in three homes in Newark, New Jersey were evacuated after the earthquake due to structural concerns about the stability of their houses, according to FOX 5 New York. Building officials are looking into the scope of the damage.

Elizabeth Page, a Queens resident, was one of many across the region who happened to have cameras rolling when the quake struck. She captured footage of items in her apartment shaking. The video shows her sitting on the floor, suspecting that an earthquake is affecting her apartment in New York City.

Footage taken by Richard Snyder captures a few seconds of the earthquake, as felt from his home in Pennsylvania’s Lehigh Valley.

"What the (expletive) is that?" Snyder is heard saying in the video. "What the hell? We’re having an earthquake!"

New York City Mayor Eric Adams said first responders quickly completed assessments around the city to ensure the safety of New Yorkers.

"So far no major life safety issues reported, no reported infrastructure issues," Adams said. "But we will continue our inspections of critical infrastructure."

EAST VS. WEST: WHY EARTHQUAKES ARE FELT DIFFERENTLY ON EITHER SIDE OF THE US

New Jersey Governor Phil Murphy activated the State Emergency Operations Center Friday morning and asked that the public only call 911 in an emergency.

Newark Liberty International Airport and John F. Kennedy Airport were at a temporary ground stop shortly after the earthquake, and flights were held until the runways could be inspected for damage. Passengers were informed by United Airlines that change fees would be waived for any issues related to the earthquake.

Holland Tunnel traffic was also temporarily halted for inspection, as the NJ Transit rail service saw 20-minute delays due to bridge inspections.

New Jersey’s Public Service Enterprise Group (PSE&G) says they have completed inspections of their power grid and infrastructure, which includes the area around the epicenter, and have found no damage or outages from the earthquake.

Pennsylvania Governor Josh Shapiro actively monitored the situation and contacted counties about possible damage.

WHAT TO DO DURING AND AFTER AN EARTHQUAKE

Seismologists warned that those in the affected area should brace themselves for aftershocks.

Based on data from USGS, there was a 14% probability of an aftershock with a magnitude of 4.0 or higher but now a 74% probability of additional aftershocks with a magnitude of 3.0 or higher taking place within the next seven days.

The region was shaken by an aftershock that was estimated to be a magnitude 3.8 about 6 p.m Friday, prompting authorities to once again advise caution.

"Definitely — basically you never have just one earthquake," San Diego State Geologist Pat Abbott told FOX Weather. "Once the Earth has fractured in someplace and moved, that means it’s moved a lot of stress forward, which is going to cause adjoining areas to move as well."

WHAT ARE THE TYPES OF FAULTS AND HOW DO THEY RELATE TO EARTHQUAKES?

Abbott said he would expect the aftershocks to be weaker in magnitude.

"I would expect one or two aftershocks that you would feel — it won’t be as much damage, it won’t be felt by as many people, but there will be more aftershocks," he added.

Abbott said that while a 4.8-magnitude quake may feel routine to those along the West Coast, it would be felt over a wider area in the East.

Mountains in the West are constantly being pushed up, leading to crushed rocks that don't transmit seismic energy as easily as those in the East, Abbott added, So, an earthquake of the same size in the East will be felt over a much wider area than in the West.
