I felt it too, in Massachusetts! I thought it was the wind, but soon realized...wow!
I live in LOs Angeles and of course we are earthquake country.
I watch the USGS website throughout the day.
You can go there to gain a lot of info.
Here is where it was felt.
If you click on the Resp you can see where it was intensely felt.
