I work in Peekskill, NY, so pretty close to the western NJ epicenter. I was sitting in a meeting room when it happened. Oh yeah ! it was a definite jolt where I was, plenty of shaking of the building for maybe 5 seconds.
I was in college in Troy, NY in the fall of 1983, when the Blue Mountain Lake quake occurred. That was a 5.4 and it nearly knocked me out of my bed 90 miles away when it hit in the wee hours of the morning.
