New Jersey Hit by 4.8-Magnitude Earthquake: Map

A Light Earthquake Shakes New Jersey

On a Friday, a 4.8-magnitude earthquake struck in New Jersey, causing tremors felt across the New York City metropolitan area, extending from Philadelphia to Boston.

The temblor occurred at 10:23 a.m. Eastern, approximately 4 miles north of Whitehouse Station, N.J., according to data from the United States Geological Survey.

Aftershocks in the Region

Following the main quake, aftershocks, which are smaller earthquakes, can occur in the same area. These aftershocks are minor adjustments along the fault that slipped during the initial earthquake.

Quakes and Aftershocks Within 100 Miles

Aftershocks can happen days, weeks, or even years after the initial earthquake, potentially causing further damage in already affected areas.

How This Quake Compares

Since 1957, the U.S.G.S. has recorded 188 earthquakes with a magnitude of 2.5 or higher within a 250-mile radius of New York City. Among these, only seven have reached a magnitude of 4.5 or above. The recent earthquake ranks as the third-largest in the available data.
