At around 6:14 a.m. this morning, a 2.2-magnitude earthquake was reported about three miles northwest of Mohegan Lake in Yorktown, according to the United States Geological Survey. The epicenter of the quake was in Putnam Valley.
Social media was rife with posts on the quake with people from Chappaqua, Cortlandt, Lewisboro, Mahopac and Putnam Valley chiming in with their rattling experiences, though it wasn’t nearly as strong as the 5.0 earthquake our forefathers experienced here in 1783.
