'Icequakes' possible across Midwest. What is the loud phenomenon?
Locals across the Midwest, particularly in Greater Chicago, may hear a sudden "boom" over the weekend – the result of what meteorologists call a frost quake, a weather phenomenon that takes place when temperatures plummet and groundwater freezes quickly.
More than 210 million people in the United States are under cold weather advisories, as a major winter storm is forecast to spread heavy snow, sleet and dangerous ice across at least two dozen states starting on Friday, Jan. 23, and continuing into the weekend.
