A sinkhole, also known as a sink-hole, sink, swallow hole, shakehole, swallet or doline, is a natural depression or hole in the Earth’s surface which may have various causes. Some are caused by karst processes—for example, the chemical dissolution of carbonate rocks or suffosion processes in sandstone. Others are formed as a result of the collapse of old mine workings close to the surface.
Sinkholes may vary in size from 1 to 600 m (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.—-
Sinkholes also form from human activity, such as the rare but still occasional collapse of abandoned mines and salt cavern storage in salt domes in places like Louisiana, Mississippi and Texas. More commonly, sinkholes occur in urban areas due to water main breaks or sewer collapses when old pipes give way. They can also occur from the overpumping and extraction of groundwater and subsurface fluids.
Sinkholes can also form when natural water-drainage patterns are changed and new water-diversion systems are developed. Some sinkholes form when the land surface is changed, such as when industrial and runoff-storage ponds are created; the substantial weight of the new material can trigger an underground collapse of supporting material, thus causing a sinkhole.

These things are happening worldwide, they can be explained away by erosion or water getting in-between layers, but this would be plausible if say 10 or 20 happened, to date over 500 have happened all over the World, mainly the Americas North and South over the last three years, some are a few feet in size and go 300 feet down, some are 200 yards wide and go a mile deep, and all in-between. This has science and the like’s puzzles. When an event happens, you deal with it, when it happens hundreds of times in a short space of time, there has to be an equal sign (=) at the end of the question, here there is not, so what is causing holes to swallow up cars, homes and people World Wide?
Your guess is as good as mine, I have been keeping an eye on this for the past few years and the video above is from OHIO, USA Yesterday, here are pictures of more from all over the Globe. Anyone got any thoughts?
