Extreme cold causes bizarre things to happen, and that was certainly the case Wednesday in Chicago when a series of loud booms were reported.

The temperature in Chicago dropped to 23 below zero early Wednesday, one of the coldest readings ever recorded in the city.

What Chicago residents heard were likely "frost quakes," also known by the dull geological term "cryoseisms."

They occur when a rapid drop in temperature leads to a quick freeze, which causes the rock or soil to burst rather than just slowly expand, according to meteorologist Keith Heidorn. The rapid bursting sounds like noisy quake, along with possible shaking.
