I finally felt... something... yesterday, relating to the quake. At precisely 6PM, I felt an aftershock that lasted for a few seconds. The sensation was similar to hearing/feeling an 18-wheeler going past on a bad road.
Fun fact: The strongest in NJ is 5.3 recorded in 1783. So 4.7 is up there for us.
This was the strongest recorded earthquake in NJ. The other quakes that were supposedly bigger are all estimates, since they didn't have seismographs back then. According to the USGS, the first seismograph was developed in 1890. https://www.usgs.gov/faqs/seismomete...w-do-they-work

How did they record how strong it was in 1783. I'm curious as to the "technology" they would have used?
I was in Atlantic City at the time and felt nothing. Strange thing is that my sister felt it in Cape May though.
