This was the second EQ I've experienced in New Jersey. It was funny, my wheelchair started moving, then the rope from my jib crane started swing back and forth, the blinds began banging against the trim. It was just Left right movement, No up and Down, or wave like motion. about 1 minute 1/2 long. The motions was quite smooth. I am by the shore, the geolgy is about 150-200 feet of sand/clay on top of bedrock.
The first NJ quake about 35 years ago was like a wave, I heard it before I felt it and it felt like a wave as it moved through the house.It was like 3-5 seconds long, That house was on bedrock. That was a NJ fault, this one was in Virginia. About 400 miles away.
