One explosion was even caught on a doorbell camera. The noises are loud enough to set off car alarms and wake people from their sleep.

“It rattles the windows, it sounds like a firework going off in my backyard,” said Dallis Stumpf.

The sounds are especially startling to those who have kids.

“She’s two-years-old and she comes out, ‘mommy what is that?’ and she freaks out,” Stumpf said.

The loud bangs have attracted so much attention that a Facebook group has been created to track the times and direction of the explosions. It now has more than 500 followers.
