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 thatÂ’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. The quake was 3 miles below ground and could also be felt in Mahwah, Wanaque, Oakland, Franklin Lakes, West Milford and Paterson.
