Another Mysterious Explosion Under Investigation In Bucks Co.

After several days of inactivity, there has been another mysterious explosion in Bucks County.

Residents in Milford Township report an explosion on the morning of June 7. A hole in the ground is visible off Brick Tavern Road, and WFMZ shared a picture of it here.

Resident Emma Richards told WFMZ she thought her house was "blowing up." Investigators were on the scene that day, and blocked off the road, according to that report.

Earlier in last week, Pennsylvania State Police, which is investigating the explosions, said reports had ceased since May 29. A State Police spokesperson was not immediately available Monday evening to say if there had been additional reports since the Thursday incident in Milford Township.

State Police confirmed it is investigating the more than 20 unexplained explosions reported in April and May. In a statement, State Police said law enforcement is taking the situation "very seriously."

Few details have emerged about what is causing the explosions. They are not due to construction or environmental causes, authorities have concluded.

The FBI and the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) have been called in to assist.

The explosions have centered in Upper Bucks County, from Quakertown to Point Pleasant, according to State Police. The situation has drawn national attention from the news media, including coverage from the Washington Post and the New York Post.

"Keeping everyone safe is our shared number one priority. Fortunately to date no one has been injured; however, we are attempting to prevent someone from accidentally getting injured by these explosions, including the individual responsible," State Police said in last week's statement.

Residents should remain vigilant and pay attention to events and people around them, state police advise.

"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 submitted by calling Lehigh Valley Crime Stoppers at 1-800-426-Tips or the Dublin station 215-249-9191. Tips can be anonymous. Callers should ask for Trooper Jordan Houck.
