Second Earthquake Strikes New York in as Many Days
Weatherboy Team MeteorologistMay 20, 2023
Just a day after an earthquake struck just outside of New York City, a fresh earthquake hit New York Friday evening followed by another somewhat stronger earthquake just northeast above the U.S. / Canada border in Ontario today. Unlike the first earthquake north of New York City that generated hundreds of reports to the USGS website and their “Did you feel it?” reporting tool, these two recent earthquakes were barely felt and caused no damage nor injuries.
Last night, at 10:57 pm, a magnitude 1.6 earthquake hit Rodman near Watertown, New York. There have been numerous earthquakes in this part of New York state for many weeks now, the strongest being a magnitude 3.8 event which struck on February 7.
According to the Northeast States Emergency Consortium (NESEC), New York is a state with a very long history of earthquake activity that has touched all parts of the state. Since the first earthquake that was recorded in December 19, 1737, New York has had over 550 earthquakes centered within its state boundaries through 2016. It also has experienced strong ground shaking from earthquakes centered in nearby U.S. states and Canadian provinces. Most of the earthquakes in New York have taken place in the greater New York City area, in the Adirondack Mountains region, and in the western part of the state.
While many of the earthquakes to hit New York are weak or mild like today’s, some have been damaging. Of the 551 earthquakes recorded between 1737 and 2016, 5 were considered “damaging”: 1737, 1929, 1944, 1983, and 2002.
While most of New York’s earthquakes have been in the Upstate, New York City has also seen damaging earthquakes over the years. At about 10:30 pm on December 18, 1737, an earthquake with an unknown epicenter hit New York with an estimated magnitude of 5.2. That quake damaged some chimneys in the city. On August 10, 1884, another 5.2 earthquake struck; this quake cracked chimneys and plaster, broke windows, and objects were thrown from shelves throughout not only New York City, but surrounding towns in New York and New Jersey too. The shaking from the 1884 earthquake was felt as far west as Toledo, Ohio and as far east as Penobscot Bay, Maine. It was also reported felt by some in Baltimore, Maryland.
In addition to the New York earthquakes, USGS also reported that one hit the Ontario province of Canada this morning at 7:36 am. This magnitude 2.1 event struck south and west of Perth, north and west of the most recent New York earthquake.
