ST. FRANCOIS COUNTY, MO (KTVI)-- The intense cold may be causing problems you`ve never heard of, but they're hearing them loud and clear in St. Francois County.

Jarring noises that sound like gunshots and fireworks through the night.

Residents say they heard noises all night long that may have been caused by the unbearable frigid weather.

Dave and Charlene Hagerty own an insurance company in Park Hills. They live here in Ter du Lac and between midnight and six Monday morning they heard all sorts of loud noises.

She posted her experience on Facebook and found out at least a half dozen people across St. Francois County heard similar things in Bonne Terre, Park Hills, Farmington and Ter du Lac.

She did some research on the internet and discovered what they all heard may have been frost quakes or ice quakes.  Meteorologist Dave Murray says it`s the same principal as potholes, water gets in the soil and freezes.

“It refreezes, it thaws, it freezes, and thaws and it creates cracks in the earth and they sound like gunshots. There`s rumbling. There can be damage from them. You can get cracks in foundations, things like that,” he said.

There was no damage. Police did not receive any calls.
