What is the sinkhole capital of the world?

What caused the Golly Hole sinkhole?
Golly Hole sinkhole
The Golly Hole near County Road 84 and Overhill Road in Shelby County was dubbed “The December Giant” and “The Golly Hole.” It is thought to be more than 325 feet long, 300 feet broad, and 120 feet deep, making it one of the United States’ biggest sinkholes.
What is the most dangerous sinkhole?
A cover-collapse sinkhole is the most hazardous type of sinkhole. The bedrock is covered with a layer of clay in these situations. Groundwater, on the other hand, dissolves an underground cavern beneath this ground cover. Gradually, sediments from the bottom erode into the cave from the sides.
Has anyone died from a sinkhole?
In 2010, a sinkhole 65 feet broad and 300 feet deep opened, consuming a three-story structure and surrounding infrastructure. At least 15 people were killed in the disaster. Sinkholes aren’t unusual, but deaths and severe damage as a result of them are.

What’s at the bottom of a sinkhole?
Occasionally, a sinkhole may signal the presence of an underground cave. Sinkholes are most prevalent in limestone or other carbonate rock, salt deposits, and soluble rocks like gypsum that can be dissolved naturally by groundwater circulation.
Which state has the most sinkholes?
“Florida, Texas, Alabama, Missouri, Kentucky, Tennessee, and Pennsylvania are the states that have the highest risk of sinkhole damage.”
Can a sinkhole kill you?
Sinkholes are a frequent occurrence in Florida’s limestone-rich soil, which readily dissolves the calcium carbonate into solution, turning the ground into a slushy mix that washes away beneath buildings constructed on top of it. They seldom kill people, though.
Can a sinkhole be fixed?
The method for repairing a sinkhole is determined by the size, stability, location, geological context, and immediate cause of the hole. A tiny, sturdy hole in an open area may simply be filled with dirt and restored with ground cover in general.
Can you survive a sinkhole?
The best strategy to avoid getting trapped in a sinkhole is not to fall into one. As the ground begins to fill with water, trees and fence posts begin to lean or fall over. Because the sinkhole drains away water, vegetation may wilt and die.
How deep can a sinkhole be?
What is a “sinkhole”? A sinkhole is an area of ground with no established external drainage, such as when it rains and the water stays within the sinkhole. Sinkholes range in size from a few feet to hundreds of acres and can vary in depth from less than 1 to more than 100 feet.
How likely is a sinkhole?
According to the USGS, 20% of the land in the United States is vulnerable to sinkholes. Sinkhole damage is most common in Florida, Texas, Alabama, Missouri, Kentucky, Tennessee, and Pennsylvania.The evaporite rocks underlie roughly 35 to 40 percent of the United States, although in many regions they are buried at significant depths.
What is inside a sinkhole?
A sinkhole is a depression in the ground with no natural outlet for surface drainage. This basically implies that all of the water stays within the sinkhole when it rains, and it typically flows into the subsurface.
What is the smallest sinkhole?

- Trees or fence posts that tilt or fall.
- Doors or windows become difficult to open or close.
