DENVILLE, NJ - Police today assured residents that explosions heard and felt throughout the area are nothing to worry about, just routine tests taking place at Picatinny Arsenal.

The testing of armaments, explosives and other things that make noise is routine activity at the military complex, situated in Jefferson and Rockaway Township, police said. Nevertheless, local authorities sometimes find themselves deluged with phone calls when residents hear the booms. Today was one of those days.

"Throughout the course of the day, the Denville Police Department as well as other police departments in the surrounding towns, have been receiving numerous reports of loud explosions that can be both heard and felt by residents," said Denville Police in a statement. "It has now been determined that the cause of these explosions was testing being conducted at Picatinny Arsenal in Rockaway Township."
