Tiny Earthquake Hits Parts of Lower Hudson Valley

That small rumble you might have felt wasn't the bass of your neighbor's stereo.

It was an earthquake. A very small earthquake.

The US Geological Survey announced that a magnitude 1.0 earthquake affected an area from Port Chester, New York to Greenwich, Connecticut. NBC NY reports that the tiny quake happened at about midnight on Tuesday.

According to Won-Young Kim, a research professor at the Lamont-Doherty Earth Observatory in Palisades, a magnitude of 1.0 would "barely be felt by people."

"It's not that rare there," said Kim, referring to the area around the Port Chester-Connecticut border. "Every couple years it happens."

The earthquake did not originate from the Ramapo Fault Line, a zone spanning over 185 miles in New York, New Jersey, and Pennsylvania. There has been concern in recent years over the Ramapo fault and it's close proximity to the Indian Point Nuclear Power Plant.
