Late Sunday while watching the Broncos get trounced by the Seahawks, residents in Hannibal and Paris, Missouri, heard strange sounds coming from their homes.
Thinking that the source was snowballs or fallen tree limbs, many curiously looked around outside. When they were unable to identify a source, some called the police.
Those noises turned out to be ground level tremors known as frost quakes.
According to an Associated Press article, scientists say that the communities, along with several other areas of the United States, experienced cryoseisms as a result of the large temperature swing in early February. The tremors usually occur in places where the temperature shifts rapidly.
If you have lived in Missouri for more than a week, you know that temperature shifts happen all the time. Don't like the weather? Wait a few hours.
Although the magnitude is small, experts say that if a frost quake is felt, homeowners may want to check for foundation cracks and watch for damages in water and natural gas lines.
