We live in the center of Morris County NJ. Our entire neighborhood congregated in the street together. Some older folks, some babies, several dogs.
Alot of talking over each other, wondering what it was. My DH brought his phone out and we got to read the local alerts and the ones from NYC 30 miles away.
When it started rattling, I thought it was an oversized truck barreling down our small road. The papers piled next to me on the coffee table slid off. My coffee cup vibrated and sloshed a bit.
The sound was big. I first thought my furnace or water heater in basement was exploding. It lasted maybe 20-30 seconds. We were all safe, no damage found on our homes.
