Did You Just Feel That? 2.3 Magnitude Earthquake Shakes Up The Hudson Valley

HUDSON VALLEY, NY — Did you feel that? An earthquake just shook the lower Hudson Valley.

A 2.3 magnitude earthquake centered near Sleepy Hollow was felt throughout the Hudson Valley.

There have been no reports of damage or injuries.

So far, people on social media have reported feeling the quake throughout Westchester County, including Lewisboro, Bedford, Katonah, Mount Kisco, Thornwood, Chappaqua, Millwood, Armonk, Hawthorne, Pleasantville, Yorktown, Somers, Peekskill, Cortlandt, Montrose, Buchanan, Verplanck, Croton-on-Hudson, Ossining, Briarcliff Manor, Tarrytown, Greenburgh, Elmsford, Ardsley, Irvington, Dobbs Ferry, Hastings-on-Hudson, Yonkers, Mount Vernon, Pelham, Tuckahoe, New Rochelle, Mamaroneck, Rye Neck, Port Chester, Rye Brook, Scarsdale, Hartsdale, White Plains, Valhalla, Harrison, and Purchase.

According to the U.S. Geological Survey (USGS) and social media reports, the earthquake was felt as far away as Putnam County, including Brewster, Mahopac and Putnam Valley.

There were even several people from Connecticut who felt the earthquake, including residents in Greenwich, Stamford, Wilton, and Sherman. The towns are all in western Connecticut, which was closest to the earthquake.

The earthquake was a result of faulting at shallow depths in the crust, the USGS said. Although this event did not occur near a plate boundary, such "intraplate" earthquakes can and do occur. While this earthquake is relatively small globally, earthquakes of this magnitude are commonly widely felt in the eastern United States because of efficient seismic wave propagation in the region.

Earthquakes in the eastern US are infrequent, but not unexpected. In April 2024, a magnitude 4.8 earthquake was reported in nearby Tewksbury, New Jersey, approximately 60 km from Saturday's earthquake. That earthquake was widely felt across the northeastern United States.

Since 1950, 43 other earthquakes of magnitude 3 and larger have occurred within 250 km of today's earthquake. In that time range, the April 5, 2024, Tewksbury, New Jersey earthquake was the largest. The August 3, 2025, earthquake occurred in a region where faults have been previously identified and may be reactivated at any time, according to the USGS.
