The bewildering video shows officials surveying a yawning sinkhole that opened up a residential street on Chicago’s South Side after a cast iron water main dating back to 1915 broke during a massive rainstorm.
As you watch, the road collapses literally from under a parked car and it topples in!
Sinkholes are becoming a frequently recurring phenomenon.

“A sinkhole, also known as a sink, shake hole, swallow hole, swallet, doline or cenote, is a natural depression or hole in the Earth’s surface caused by karst processes — the chemical dissolution of carbonate rocks or suffosion processes for example in sandstone. Sinkholes may vary in size from 1 to 600 meters (3.3 to 2,000 ft) both in diameter and depth, and vary in form from soil-lined bowls to bedrock-edged chasms. Sinkholes may be formed gradually or suddenly, and are found worldwide. The different terms for sinkholes are often used interchangeably.” – Wikipedia MORE
