Loud boom PA

Things are usually pretty quiet around Sabrina and Todd Sterner's home near Schuylkill Haven. The loudest sound is usually their dog Hoagie barking, but Friday night something disturbed the peace.

Sabrina said, "I was just sitting here on the couch and just a big boom!" She added, "The house shook and windows shook." Todd said, "It was a boom! Real deep, you almost felt the concussion of the actual shock, nothing like a gunshot." The couple looked outside, but they couldn't see what had made the sound.

People reported hearing similar sounds in communities across the southern part of Schuylkill County, including New Philadelphia and Pottsville. The phenomena quickly became a hot topic on social media. Nicole Brown read about the sounds on Facebook before she went shopping for a Christmas tree in Schuylkill County. She said, "It makes me very curious. [It's] a little frightening. [It's] a little disturbing."

State Police at Schuylkill Haven tell us, while there can't say for sure what made the loud sounds, they suspect it is caused by people shooting guns at Tannerite canisters. The targets are known for making quite a racket when they are hit, and can be bought at some sporting good stores.

An officer at the Schuylkill Haven Borough Police Department tells Newswatch 16 that he doesn't believe the activity presents a danger to the public at this time.
