Residents across the Mid-Atlantic region experienced a brief but distinct shaking sensation late Thursday afternoon, an event the US Geological Survey has confirmed was a 4.1-magnitude earthquake along the coast of the Delaware Bay.
The quake was felt from as far south as Washington, D.C., and north to New York City and as far west as the eastern West Virginia, according to eyewitness reports filed with the USGS.
It was felt as a slight shaking in office buildings in Center City Philadelphia.
Reactions poured in almost instantly on social media as people across the region confirmed the event.
The largest earthquake to hit Philadelphia in recent memory was in 2011, when a 5.8 magnitude quake centered in Virginia sent tremors through the city and was felt from Georgia to Canada.
