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, with the epicenter in Tewksbury Township. While it was felt across the New York metropolitan area, Delaware Valley, the Washington D.C metropolitan area, and other parts of the northeastern United States between Virginia and Maine, it had a relatively minor impact, with no major damage reported. [2] [3] There were dozens of aftershocks throughout the rest of the week and into the next. [4] [5]

Contents

It was the strongest earthquake to affect New Jersey since the 5.3 Mfa 1783 New Jersey earthquake, [6] and the strongest to hit New York City since an estimated 5.0 magnitude earthquake on August 10, 1884. [7] [3]

Tectonic setting

The causative fault for the earthquake was likely in the area of the Ramapo Fault zone, [8] which extends from Pennsylvania to New York [9] and was formed by the break-up of the supercontinent Pangaea during the Late Triassic. [10] Another possible origin is the Flemington Fault, a younger fault in the same area. [11]

The Whitehouse Station, New Jersey area had previously experienced an earthquake on March 14, 2024. [12] The USGS considers this to be part of the event sequence. [13]

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 [lower-alpha 1] , at 40.689°N 74.754°W, about 1 mile (1.6 km) north of Oldwick and 5 miles (8.0 km) east of Lebanon. [14] Tremors were felt all across the Northeastern United States from Maine in the north to Washington, D.C., and Norfolk, Virginia, in the south. [3] [15]

As of April 12, over 50 aftershocks were reported, [5] [16] the strongest of which had a magnitude of 3.7 and took place about 4 miles (6 km) from Gladstone around 17:59. [2] [17] [4] The USGS projected a 12% chance of an aftershock with a magnitude greater than 3 and a 1% chance of a stronger earthquake with a magnitude above 4. [2] [3] An aftershock of 2.6 was felt about 5 kilometres (3 mi) southwest of Gladstone on about 10:25 AM local time on April 10. [18]

Impact

Several buildings in New York City, Philadelphia, and Long Island were shaken. [19] [15] The USGS estimated that the earthquake was felt by about 42 million people in the area. [15]

The earthquake interrupted a meeting of the Security Council on the Israel–Hamas war at the United Nations Headquarters in Manhattan, [20] [19] 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] [21] [22] Gas leaks were reported in Rockland County, New York, [2] and an administrative building in Morristown, New Jersey. [23] In Huntington, New York, a vehicle was damaged after falling into a sinkhole shortly after the earthquake. [24]

Up to 150 buildings were damaged across New York City, and a school gym in East New York sustained damage. [25] Four three-story houses on Seventh Avenue in Newark, New Jersey, were damaged by the earthquake. Twenty-eight residents were evacuated, but no injuries were reported. Three of the houses were "partially toppled" and were subsequently condemned. [2] [6] The upper portion of the 264-year old Col. John Taylor's Grist Mill collapsed into a road. [20] Additionally, the earthquake caused water main breaks in Essex County and Morris County. [26] [27]

Damage to a Northeast Philadelphia home was the only confirmed report of structural damage caused by the earthquake in Pennsylvania. [28]

Aftermath

The Federal Aviation Administration completely halted flights at Newark Liberty International Airport, Philadelphia International Airport [29] 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. [30] Five flights bound for Newark were diverted to Lehigh Valley International Airport in Allentown, Pennsylvania. [20]

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. [31] Amid criticism, New York City Emergency Management Commissioner Zach Iscol defended the delayed response in a press conference, saying that "Twenty minutes is very fast for a public alert," [32] and that they needed that time to confirm that it was indeed an earthquake. [31]

The PATCO Speedline was temporarily suspended for inspection "out of an abundance of caution." [6] Amtrak train speeds were restricted throughout the Northeast while railroad tracks were being inspected for damage, and NJ Transit trains on all lines were expected to be delayed by up to 20 minutes due to track inspection. [33] AirTrain Newark at the Newark Liberty International Airport was also closed for inspection while its flights were ungrounded. [2]

The Holland Tunnel, a major crossing of the Hudson River, was briefly closed for inspection between 11:00 and 11:15 local time. [19] [6] The Lincoln Tunnel was also briefly closed, [34] backing up traffic in Weehawken.

Within hours of the earthquake, a custom T-shirt shop in Manhattan began printing a joke souvenir reading "I survived the NYC earthquake April 5, 2024." The store put it on the shop window and a pedestrian took a photo of it, which was shared widely on social media, causing hundreds of sales. [35] [36] [37]

The 2008 Illinois earthquake was one of the largest earthquakes ever recorded in the Midwest state of Illinois. This moderate strike-slip shock measured 5.2 on the moment magnitude scale and had a maximum Mercalli intensity of VII (Very strong). It occurred at 04:36:59 local time on April 18 near Bellmont and Mount Carmel, Illinois, within the Wabash Valley Seismic Zone. Earthquakes in this part of the country are often felt at great distances.

The 2010 Chile earthquake and tsunami occurred off the coast of central Chile on Saturday, 27 February at 03:34:12 local time, having a magnitude of 8.8 on the moment magnitude scale, with intense shaking lasting for about three minutes. It was felt strongly in six Chilean regions that together make up about 80 percent of the country's population. According to the United States Geological Survey (USGS) the cities experiencing the strongest shaking—VIII (Severe) on the Mercalli intensity scale (MM)—were Concepción, Arauco, and Coronel. According to Chile's Seismological Service, Concepción experienced the strongest shaking at MM IX (Violent). The earthquake was felt in the capital Santiago at MM VII or MM VIII. Tremors were felt in many Argentine cities, including Buenos Aires, Córdoba, Mendoza, and La Rioja. Tremors were felt as far north as the city of Ica in southern Peru. It is the largest earthquake to hit Chile since the 1960 Valdivia earthquake.

The 2010 Baja California earthquake occurred on April 4 with a moment magnitude of 7.2 and a maximum Mercalli intensity of VII. The shock originated at 15:40:41 local time south of Guadalupe Victoria, Baja California, Mexico.

Seismicity of the New York City area is relatively low. New York is less seismically active than California because it is far from any plate boundaries. Large and damaging intraplate earthquakes are relatively rare but when they do occur in the northeastern United States the areas affected by them are much larger than for earthquakes of similar magnitude on the West Coast. The largest known earthquake in the greater New York City area occurred in 1884, probably somewhere between Brooklyn and Sandy Hook, and had a magnitude of approximately 5. The New York quakes in 2023 and 2024 were shallow quakes.

A potent magnitude 6.6 Mw intraplate aftershock occurred at 17:16 JST (08:16 UTC) on 11 April, in the Hamadōri region of Fukushima, Japan. With a shallow focus of 13 km (8.1 mi), the earthquake was centred inland about 36 km (22 mi) west of Iwaki, causing widespread strong to locally severe shaking. It was one of many aftershocks to follow the 11 March Tōhoku earthquake, and the strongest to have its epicentre located inland.

It was an intraplate earthquake with a maximum perceived intensity of VIII (Severe) on the Mercalli intensity scale. Several aftershocks, ranging up to 4.5 Mw in magnitude, occurred after the main tremor.

The 2012 Haida Gwaii earthquake occurred just after 8:04 p.m. PDT on October 27. The shock had a moment magnitude of 7.8 and a maximum Mercalli Intensity of V (Moderate). The earthquake's epicentre was on Moresby Island of the Haida Gwaii archipelago. This was the second largest Canadian earthquake ever recorded by a seismometer, after the 1949 Queen Charlotte Islands earthquake, about 135 kilometres (84 mi) away.

The 2016 Ecuador earthquake occurred on April 16 at 18:58:37 ECT with a moment magnitude of 7.8 and a maximum Mercalli intensity of VIII (Severe). The very large thrust earthquake was centered approximately 27 km (17 mi) from the towns of Muisne and Pedernales in a sparsely populated part of the country, and 170 km (110 mi) from the capital Quito, where it was felt strongly. Regions of Manta, Pedernales and Portoviejo accounted for over 75 percent of total casualties. Manta's central commercial shopping district, Tarqui, was completely destroyed. There was widespread damage across Manabí Province, and structures hundreds of kilometres from the epicenter collapsing. At least 676 people were killed and 27,732 people injured. President Rafael Correa declared a state of emergency; 13,500 military personnel and police officers were dispatched for recovery operations.

An earthquake measuring 4.4 MW on the moment magnitude scale struck 6.8 miles (10.9 km) north-northeast of Decatur, Tennessee in the eastern part of the state on December 12, 2018 at 4:14 a.m. Eastern Standard Time. The earthquake occurred at a depth of 9.0 kilometers (5.6 mi). The earthquake occurred along the Eastern Tennessee Seismic Zone (ETSZ), a geographic band stretching from northeastern Alabama to southwestern Virginia that is subject to frequent small earthquakes. The earthquake was felt throughout the Southeast, primarily in eastern Tennessee and the Atlanta metropolitan area. While relatively minor, this earthquake was the largest to occur on the ETSZ since the 4.6 MW 2003 Alabama earthquake, the third largest to have been recorded in the area, becoming the fourth largest earthquake recorded in the region. Robert Sanders from the U.S. Geological Survey told WSB-TV that aftershocks would be possible throughout the day after the quake.

The 2019 Ridgecrest earthquakes of July 4 and 5 occurred north and northeast of the town of Ridgecrest, California located in Kern County and west of Searles Valley. They included three initial main shocks of Mw magnitudes 6.4, 5.4, and 7.1, and many perceptible aftershocks, mainly within the area of the Naval Air Weapons Station China Lake. Eleven months later, a Mw  5.5 aftershock took place to the east of Ridgecrest. The first main shock occurred on Thursday, July 4 at 10:33 a.m. PDT, approximately 18 km (11.2 mi) ENE of Ridgecrest, and 13 km (8.1 mi) WSW of Trona, on a previously unnoticed NE-SW trending fault where it intersects the NW-SE trending Little Lake Fault Zone. This quake was preceded by several smaller earthquakes, and was followed by more than 1,400 detected aftershocks. The M 5.4 and M 7.1 quakes struck on Friday, July 5 at 4:08 a.m. and 8:19 p.m. PDT approximately 10 km (6 miles) to the northwest. The latter, now considered the mainshock, was the most powerful earthquake to occur in the state in 20 years. Subsequent aftershocks extended approximately 50 km (~30 miles) along the Little Lake Fault Zone.

At 7:09 AM MDT on March 18, 2020, a 5.7 magnitude earthquake hit Salt Lake City, Utah, United States, with an epicenter 6 km (3.7 mi) north-northeast of Magna, Utah, beneath the site of the planned Utah Inland Port. It was the first major earthquake to occur within the Salt Lake Valley since the city was founded, the state's strongest earthquake since the 1992 St. George earthquake, and the first earthquake of comparable magnitude to occur near Salt Lake City since 1962, when a magnitude 5.0 earthquake struck a similar location in Magna.
