Some locals were woken up by the rumbling and others slept right through it.
"There wasn't much shaking," one person wrote on an earthquake-tracking website. "It was very quick and ended with a very loud bang.
"Nothing fell or broke from what I can tell. Haven't been outside as it's still 2:30 in the morning."
"We live in East Freehold , NJ," another said. "The dogs couldn’t settle down 15 minutes prior to quake.
"They wouldn’t come inside where they live with us. Woke me out of sleep, felt like a jackhammer going under our house, lasting approximately 10 seconds."
