A preliminary 4.8-magnitude earthquake struck near Lebanon, New Jersey, Friday, shaking the ground from New York City to Philadelphia and beyond.
The USGS said the quake originated near Whitehouse Station, New Jersey, around 10:30 a.m. ET. It struck about 45 miles west of New York City and 50 miles north of Philadelphia.
Aftershocks were reported a few hours later at 6 p.m. ET in New York City, according to FOX 5 NY.
A 2.0-magnitude aftershock was recorded near Bedminster, New Jersey, an hour after the initial quake. USGS figures showed the quake could have been felt by more than 42 million people.

"Is it an earthquake?" Soeripto wondered aloud, then asked if it was all right to go ahead. She did, but soon diplomats’ phones blared with earthquake alerts.

Residents in the Northeast say they felt shaking for several seconds, likening it to when the washing machine is off balance in your home, "but way more intense."

Earthquakes of this magnitude are rare on the East Coast because the East Coast does not lie on the boundary of tectonic plates, FOX 5 New York reports. The biggest Eastern quakes usually occur along the mid-Atlantic Ridge, which extends through Iceland and the Atlantic Ocean.

Quakes on the East Coast can still pack a punch, as its rocks are better than their western counterparts at spreading earthquake energy across long distances.
According to the FOX 29 weather team, the last time the Northeast saw an earthquake of this size was 2011, and it was felt "up and down the East Coast." That earthquake was a magnitude 5.8, the strongest quake to hit the East Coast since World War II. The epicenter was in Virginia.
That earthquake left cracks in the Washington Monument and forced the evacuation of the White House and Capitol.
The scale used to determine the severity of earthquakes goes up to 10, putting Friday's earthquake about halfway on the scale. But there's a caveat: A 4.0 is 10 times bigger than a 3.0.
"The higher the number, the more energy coming out," FOX 29 explains. "We’re about halfway on the scale: the higher you go, the more shaking and more dramatic you get. There’s very big jumps."
