The U.S. Geological Survey says it recorded the quake around 6:30 p.m. Monday in the area of Morris Plains. According to the USGS, a 1.7 magnitude earthquake 5 kilometers underground wouldn't be felt by most people except under favorable conditions.

Jessica Turner, a USGS geophysicist, says this tremor was noticeable because its epicenter was directly beneath Morris Plains. Morris Plains Police Lt. Michael Koroski says police received about 25 calls reporting a loud booming noise. Workers at the 911 center felt the quake as calls came in.

No damage was reported and there were no requests for service because of the quake, according to the Morris County Office of Emergency Management.
