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.

Lower Hudson Valley earthquakes through the years: 

1783 — The epicenter of a magnitude 5.0 earthquake may have been the Westchester-Putnam county line and was felt as far south as Philadelphia.

1884 — A magnitude 5.2 earthquake was centered off Rockaway, Queens, causing property damage but no injuries to people. A dead dog was reported.

1970 to 1987 — Between these years, instruments at the Lamont-Doherty Observatory in Rockland County recorded 21 quakes in Westchester and two in Manhattan.

October 1985 — A magnitude 4.0 earthquake was centered in an unincorporated part of Greenburgh between Ardsley and Yonkers. Tremors shook the metropolitan area and were felt in Philadelphia, southern Canada and Long Island.

November 1988 — A quake 90 miles north of Quebec City in eastern Canada registered magnitude 6.0 with tremors felt in the Lower Hudson Valley and New York City.

June 1991 — A 4.4-magnitude quake struck west of Albany, rattling homes.

April 1991 — A quake registering between magnitude 2.0 and 2.6 struck Westchester and Fairfield, Conn. It lasted just five seconds and caused no damage.
