An earthquake shook the densely populated New York City metropolitan area Friday morning, the U.S. Geological Survey said, with residents across the Northeast reporting rumbling in a region where people are unaccustomed to feeling the ground move.

The agency reported a quake at 10:23 a.m. with a preliminary magnitude of 4.8, centred near Lebanon, New Jersey, or about 45 miles west of New York City and 50 miles north of Philadelphia. USGS figures indicated that the quake might have been felt by more than 42 million people.

New York City's emergency notification system said in a social media post more than 30 minutes after the quake that it had no reports of damage or injuries in the city. The Fire Department of New York said on social media about an hour after the quake that it was "responding to calls and evaluating structural stability" but that there are "no major incidents at this time."

Amtrak said it was inspecting its tracks and had speed restrictions in place throughout the busy Northeast Corridor. New Jersey Transit posted on X that its train system was subject to delays caused by bridge inspections. The Philadelphia area's PATCO rail line suspended service out of what it said was "an abundance of caution."

People in Baltimore, Philadelphia, Connecticut and other areas of the Northeast reported shaking. Tremors lasting for several seconds were felt over 200 miles away near the Massachusetts-New Hampshire border. In midtown Manhattan, traffic grew louder as motorists blared their horns on shuddering streets. Some Brooklyn residents heard a boom and their building shaking.

In New York City's Astoria neighbourhood, Cassondra Kurtz was giving her 14-year-old Chihuahua, Chiki, a cocoa-butter rubdown for her dry skin. Kurtz was recording the moment on video, as an everyday memory of the dog's older years, when her apartment started shaking hard enough that a 9-foot (2.7-metre-tall) mirror banged audibly against a wall.
