On April 5, 2024, at 10:23 EDT (14:23 UTC), a Mw 4.8 earthquake occurred in the U.S. state of New Jersey. While felt across the New York City and Philadelphia metropolitan areas and other parts of the northeastern United States, it had relatively minor impacts, with no major damage reported in New York State.[2]
According to the United States Geological Survey (USGS), the earthquake was the third-strongest to affect the New York region in recorded history.[3] It was the biggest earthquake with an epicenter in New Jersey since the 5.3 Mfa 1783 New Jersey earthquake,[4] and the strongest earthquake to hit the New York City area since an estimated 5.0 magnitude earthquake in 1884.[5]
Tectonic setting
The earthquake took place along the Ramapo Fault,[6] which extends from Pennsylvania to New York.[7] The earthquake took place in an area where faults had been previously identified and had the potential to become active again at any moment.[6]
Earthquake
The earthquake had a moment magnitude of 4.8 and a depth of 2.9 miles (4.7 km). Its epicenter was in Tewksbury Township, New Jersey, at 40.683°N 74.753°W, which is about 1 mile (1.6 km) north of Oldwick and 5 miles (8.0 km) east of Lebanon, along the Ramapo Fault.[6] The strong side of the quake was detected in portions of Hunterdon and Somerset counties, including the cities of Somerville, Bedminster, and Bridgewater. Tremors were felt all across the Northeastern United States from Maine in the north to Washington, D.C., and Norfolk, Virginia, in the south.[8][9]
An aftershock with a magnitude of 2.0 took place near Bedminster at around 11:20 a.m. local time. The USGS projected a 46% chance of an aftershock with a magnitude greater than 3 and a 3% chance of an aftershock with a magnitude above 5 within a week of the initial impact.[2]
Impact
Several buildings in New York City, Philadelphia, and Long Island were shaken.[10][9] The USGS estimated that the earthquake affected about 42 million people in the area.[9]
The earthquake interrupted a meeting of the Security Council at the United Nations Headquarters in Manhattan[10] while a performance at the New York Philharmonic was briefly delayed by cell phones sounding an alert at 11:02, which was sent about 40 minutes after the earthquakes were felt.[2][11][12] A gas leak was reported in Rockland County, New York.[2]
Four three-story houses on Seventh Avenue in Newark, New Jersey, were damaged by the earthquake. Residents were evacuated, but no injuries were reported. Three of the houses were "partially toppled".[2]
Response
The Federal Aviation Administration paused flights at Newark Liberty International Airport and John F. Kennedy International Airport. Arrivals into Baltimore/Washington International, LaGuardia, and Teterboro Airports were delayed.[2] The air traffic control tower at Newark Liberty International Airport was also evacuated.[13]
The first emergency alert sent to New York City residents came 26 minutes after the earthquake to subscribers of the Notify NYC service. A Wireless Emergency Alert was sent out to the broader region even later, with New Yorkers reporting it arriving 40 minutes after the earthquake.[14] Amid criticism, Emergency Management Commissioner Zach Ischol defended the delayed response in a press conference, saying that "Twenty minutes is very fast for a public alert,"[15] and that they needed that time to confirm that it was indeed an earthquake.[14]
The PATCO Speedline temporarily suspended service for inspection "out of an abundance of caution."[16] Amtrak train speeds were restricted throughout the Northeast while railroad tracks were being inspected for damage, and NJ Transit trains are expected to be delayed by up to 20 minutes.[17] AirTrain Newark at the Newark Liberty International Airport was also closed for inspection while its flights were ungrounded.[2]
The Holland Tunnel was temporarily closed for inspection.[10]
