WEST NYACK, NY — An earthquake occurred Thursday night in Rockland County on the Hackensack River not far from the New York Thruway. The quake was recorded at 9:41 p.m.
The magnitude was just 1.1 on the Richter Scale, so you might not have felt it.
“Because they’re very small, being close allows us to see them,” said Mitchell Gold, network manager for the Lamott Cooperative Seismic Network. “We have enough instrumentation close to New York that allows these things to be seen.”
Here’s where the U.S. Geological Survey pinpointed it:
• 0.7 mile east-southeast of West Nyack, New York
• 2.8 miles east of Nanuet, New York
• 3.9 miles northeast of Pearl River, New York
• 4.1 miles south-southeast of New City, New York
• 72.9 miles northeast of Trenton, New Jersey
The depth was about about 1.9 miles.
The observatory has stations all over the New York metro area just “listening” and recording seismic activity, Gold said. There’s one in Central Park, there’s one in New Paltz, and several others around New York and New Jersey.
This little quake was picked up by several of their stations. Having better equipment and more stations makes the difference with the smallest quakes, Gold said.
Did you feel it? If so report it on the event page run by the Lamott Doherty Earth Observatory (right here in Palisades) for the U.S. Geological Survey.
