Some residents in northern New Jersey awoke to a small earthquake early Monday.
The temblor, with a magnitude of 2.0, struck at 1:19 a.m. and was centered in Ringwood, a community that's still dealing with downed trees and power outages from Sandy.
Geophysicist Jessica Turner at the National Earthquake Information Center says some people reported hearing a loud boom. Turner says those on upper floors of a home might have felt shaking or saw objects on walls vibrate.
Ringwood police say there are no reports of damage.
Turner says the last earthquake in New Jersey had a 2.2 magnitude and was recorded in February 2010.
