"Ice quakes" heard across Illinois
These young pear blossoms were protected from frost on Tuesday by a coat of ice in an orchard on Voorhies Road owned by Naumes, Inc. Overhead sprinklers are used to coat the sensitive plants with ice, protecting the blossoms on cold nights so they’ll remain viable and eventually produce fruit. Other methods of preventing frost damage include portable orchard heaters and wind machines. Despite recent sunny days, nighttime lows could still drop below freezing. - Jim Craven

SPRINGFIELD, Ill. (WICS/WRSP) — Have you been hearing startling pops and bangs?
Well, those startling pops and bangs you're hearing isn't your imagination playing tricks on you. It's the natural phenomenon known as "Cryoseism".
More commonly called an "ice quake" or "frost quake", it's actually a minor seismic event caused by the sudden cracking action in frozen soil or rock that's saturated with water or ice.
As water drains into the ground and freezes with the extremely cold temperatures we're experiencing, it expands under colder temperatures and puts stress on its surroundings.
This stress builds up until relieved explosively in the form of a cryoseism and that's when you hear the loud pops and bangs.
