Authorities say a small earthquake has struck central New Jersey, rattling windows and alarming residents of several communities.
Won-Young Kim, a seismologist at the Lamont-Doherty Earth Observatory in Palisades, New York, says a quake with a preliminary magnitude of 3.0 was recorded at 10:34 p.m. Monday, centered in the Morris County communities of Rockaway, Dover and Morris Plains.
There were no immediate reports of damage or injuries. Quakes of magnitude 2.5 to 3 are the smallest that can generally be felt by people.
Police say the quake triggered a flood of emergency calls, with residents reporting a sound like an explosion and houses shaking.
Kim says small earthquakes are not unusual in that area of New Jersey.
