Feb 19th, 2009 | MORRISTOWN, N.J. -- February has been a shaky month for northern New Jersey. Literally.
Scientists say five earthshaking events have hit the area, most in Morris County.
At least three are considered earthquakes; two may have been aftershocks.
Rutgers University geology professor Alexander Gates says it's uncommon to get five seismic events so close together. He says New Jersey usually gets two or three small quakes a year.
On Feb. 2, a magnitude 3.0 quake rattled windows and alarmed residents of Rockaway, Dover and Morris Plains. A magnitude 2.2 quake on Valentine's Day shook residents in Boonton and Montville.
An aftershock in Montville on Monday was too weak to be noticed by most people, as was one near Teterboro Airport an hour later.
A magnitude 2.3 quake hit Wednesday morning near Dover.
