Earthquake Reportedly Felt In CT: Did You Feel It?

A 2.3 magnitude earthquake originating out of the Hudson Valley, New York, Tuesday morning was felt in parts of Connecticut, according to the United States Geological Survey.

The earthquake originated out of Sleepy Hollow, New York, on Tuesday at 10:17 a.m. Sleepy Hollow is about 30 miles from the Connecticut border.

According to the U.S.G.S., there have been nearly 800 reports from people who said they felt the earthquake.

There were 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.

NBC CT chief meteorologist Ryan Hanrahan wrote on social media, "A small earthquake shook parts of our area this morning. The USGS reports a 2.3 magnitude quake centered in Sleepy Hollow, NY, and it was felt in parts of Westchester and Fairfield Counties."

A 1.9 magnitude earthquake was reported in January in East Haddam, CT.

Earthquakes are rare in Connecticut, but in 2025 at least a few minor ones were reported.

A 2.0 magnitude quake rocked New Britain in May 2025. USGS geologists logged a 1.8 magnitude earthquake in Essex Village in May. In January 2025, a 1.8 magnitude earthquake was also reported in Moodus, a village in East Haddam.
