I'm in Brooklyn and felt it while on a call with an NJ resident who was the first to say "are we having an earthquake??" Do earthquakes have a propagation speed? Might she have felt it before me?

Yes, the speed of sound (through the earth, so faster than the speed of sound in air); yes. In California, typically usgs has earthquakes posted before I can feel them. They didn't have this one a few minutes after I felt it, so I feel like automatic earthquake detection is off in this area of the US.

Same experience -- felt a shaking; thought maybe a heavy truck had passed by for a second, then saw that all the monitors were swaying. Checked USGS and saw nothing, so figured it was nothing, because on the west coast they have the reports up lickety split. Half hour later everyone's phone started buzzing with the automated alert.

I distinctly remember the first time I created a Twitter account (& probably became aware of Twitter being a thing) was the day when a similar earthquake was felt in NYC back in 2011...

Yes! It was in the fall. The epicenter of that one was near Virginia though I think. Edit: Here it is. It was the end of August which I consider the Fall cause that's when the Fall semester starts for me ^^ https://en.wikipedia.org/wiki/2011_Virginia_earthquake

I remember this earth quake! I missed it lol. I happened to be driving and we got out of the car to see a tv telling us how we got hit with an earth quake and my friend and I looking at one another like "what did we miss". This time I happened to be on the second floor of a small office building. I was about to run out of the building if it started to get worse I wasn't sure it wasn't the building having an issue.

Felt that very strongly in southern Westchester county NY. Not like the 2011 earthquake I felt in NYC, which was kind of slow and made the building I was in sway violently; this was more like the vibrations from a huge truck passing nearby, but more intense. Loud and very unpleasant, about 15 seconds duration. Did not like that at all, am now inspecting all our services like gas and water for disruption, checking for cracks and so on.

For those of you who didn't grow up in earthquake country, some tips: DO NOT get into a doorway, that's a myth. It's not a terrible place to be if it's a doorless frame, but if there is a door, it's more likely you get injured from the door smacking you than the earthquake. DO get under a strong table. That's the safest place to be in a quake if it happens when you are indoors. If you're outside get as far away from…

I suppose depending on the structure and the individual's inclination strong table might be a good call.

But in my single family home situation it really doesn't take more than a few seconds and I can be out the door provided I'm not knocked off my feet entirely type situation.

I can't find any source that matches what you're saying. "Tremor" seems to always be defined in terms of earthquakes, either as a synonym or a "very small earthquake", which wouldn't even apply here because this was relatively large and clearly perceptible to the average person.

As someone who lived for decades in a seismic country, I’d say that tremors can also be perceived. The difference lies mostly in the damage generated by the event.
