It is not known as a place where earthquakes often occur.
But New Jersey has been hit by more than 200 quakes in the past three months.
The United States Geological Survey (USGS) detected a magnitude 2.2 quake at around 1:44 a.m. ET on Wednesday.
The aftershock struck about seven miles from the epicenter of the April quake, and was felt hundreds of miles away in major cities including New York City and Baltimore, Maryland.
It is the 202nd earthquake since the 4.8 magnitude quake struck the state on April 5, shaking skyscrapers in New York’s famous skyline.

The hundreds of aftershocks are a result of the way rocks readjust after the large aftershock in the spring.
“Felt another earthquake in New Jersey at 1:45 AM. Heard an explosion, a tsunami approaching the house, followed by 30 seconds of shaking in my house,” one New Jersey resident shared on X.
However, not all residents felt the ground shake because it was so light.
A study from Michigan Tech University found that people generally do not feel earthquakes of magnitude 2.5 or less.
Damages from 2.5 to 5.4 are often felt, but cause only minor damage.
And buildings and other structures can sustain damage if a force of 5.5 to 6.0 hits.
The USGS noted that aftershocks typically become less frequent as time passes, “although they can persist for days, weeks, months, or even years for a very large main shock.”
New York Governor Kathy Hochul said the April 5 earthquake was “one of the largest on the East Coast in the past century.”
The last time New Jersey was hit was in 1738, when it measured 5.3.
People in Baltimore, Philadelphia, Connecticut and other areas in the Northeast reported tremors. The tremors lasted about 20 seconds and were felt more than 200 miles away, near the Massachusetts-New Hampshire border.
The United States Geological Survey (USGS) detected a magnitude 2.2 earthquake in California at approximately 1:44 a.m. ET on Wednesday.
The aftershock struck about seven miles (11 kilometers) from the epicenter of the April quake, which was felt hundreds of miles away in major cities including New York City and Baltimore, Maryland.
Social media users shared posts about the earthquake, which was also felt in New Jersey, Virginia and Philadelphia.
In a video from a New Jersey home, a dog can be seen suddenly sitting up seconds before the room begins to shake violently and items fall over.
And Boonton Coffee shared a video of their store shaking before customers fled outside.
A camera in a barbershop captured the moment an earthquake shook the shop. A customer grabbed his son, lifted him up and carried him outside.
On April 15, at least 15 aftershocks were detected in the state.
The “epicenter” in Tewksbury is on the Ramapo Fault, the longest system of faults in the northeastern United States. The fault formed 400 million years ago, making it much older than the 28-million-year-old San Andreas in California.
A fault line is a place where there is a long break in the rock that forms the earth’s surface. Here the chance of earthquakes is greater.

The system stretches from northern New York State, through New Jersey, and into Pennsylvania. Experts have long believed that the system could produce a major earthquake.
Kenneth Miller, a professor at Rutgers University, told DailyMail.com in an earlier interview that the Ramapo Fault formed when continents first began pushing against each other hundreds of millions of years ago.
‘[The system] “Reactivated 200 million years ago, causing about four miles of movement,” he explained.
‘When the Atlantic Ocean formed about 198 million years ago, it stopped.
The fault line remained active, but has since diminished to small movements.
‘A magnitude 6 to 7 earthquake is possible [for New Jersey]but that seems highly unlikely, Miller said, explaining that the Ramapo fault line doesn’t produce anything above a magnitude 3 on average.
