'Human Activity' Behind Bucks Co. Explosions: State Police

Human activity, not natural or environmental factors, is behind the series of unexplained explosions in Bucks County in recent weeks, State Police have confirmed.

More than 20 mystery explosions have been reported in Upper Bucks County since April 2. The blasts are now being investigated by State Police, the FBI and the ATF.

Since residents began hearing the loud booms last month, many have speculated on what is causing them. Several theories, including that they are linked to fracking, have been circulated. At this time, however, investigators are focusing on human activity as the cause of the blasts and are asking for residents to report any suspicious behavior, spokesman Trooper Marc W. Allen confirmed to Patch Wednesday.

The explosions have been reported throughout Upper Bucks County, from Quakertown to Point Pleasant, and typically occur in the overnight hours.

State Police is "counting on assistance from members of our community to keep our counties safe." All residents are being asked to remain vigilant and pay attention to events and people around them.

"Regardless of how insignificant you think your tip may be, we strongly encourage you to come forward with your information," he said in the statement.

Tips can be anonymous. Submit a tip by calling Lehigh Valley Crime Stoppers at 1-800-426-Tips or the Dublin station 215-249-9191.
