Geography. According to the United States Census Bureau, the city has a total area of 0.83 square miles (2.15 km2), all land. Fountain is claimed as the sinkhole capital of the United States of America due to the prevalence of karst topography.Where do sinkholes occur the most in the world?
They tend to occur most often in places where water can dissolve the bedrock (especially limestone) below the surface, causing overlying rocks to collapse. Florida, Texas, Alabama, Missouri, Kentucky, Tennessee, and Pennsylvania are most sinkhole-prone.What state is known for sinkholes?
"The most damage from sinkholes tends to occur in Florida, Texas, Alabama, Missouri, Kentucky, Tennessee, and Pennsylvania."Why is Florida the sinkhole capital?
Florida may not be susceptible to earthquakes, but the geography of the state is the perfect environment for sinkholes. And the sinkholes Florida gets are worsening with each passing year as a result of land development and climate change, according to the Florida Museum's Thompson Earth Systems Institute.How do sinkholes form?
Which city in Florida has the most sinkholes?
While Hernando, Hillsborough, and Pasco counties are known as Florida's "Sinkhole Alley," Randazzo says nearby Polk County, Lakeland specifically, is also a hot spot.Why does Florida get so many sinkholes?
Florida's GeologyWhen water like rain flows through the porous limestone, it slowly dissolves the aquifer's limestone forming a landscape called karst, known for springs, streams and even sinkholes. Much of west Central Florida is made up of this landscape, making it very active for sinkhole formation.
What part of Florida is safest from sinkholes?
Technically, no. The entire state of Florida is underlain with carbonate rocks, therefore, sinkholes could theoretically appear anywhere.Where is the largest sinkhole in the United States?
Alabama claims to have the largest recent collapse sinkhole. It is called the “Golly Hole” and is located in Shelby County in the central part of the state. It collapsed suddenly in 1972. The sinkhole is about 325 feet long, 300 feet wide, and 120 feet deep.What's at the bottom of sinkholes?
Sinkholes are common where the rock below the land surface is limestone or other carbonate rock, salt beds, or in other soluble rocks, such as gypsum, that can be dissolved naturally by circulating ground water.What is the scary biggest sinkhole in the world?
Located in Fengjie County in China, Xiaozhai Tiankeng — which roughly translates to "the Heavenly Pit" — is the world's deepest sinkhole. It is 2,172 feet (662 meters) deep and was formed over the limestone Difeng cave, which was carved out by an underground river, which still flows beneath the sinkhole.What is the top sinkhole in the world?
Xiaozhai Tiankeng – the deepest sinkhole in the world (over 650 meters), located in Fenjie County of Chongqing Municipality.Where is sinkhole Alley in Florida?
There are three counties surrounding Tampa in Florida's central swath that compose Sinkhole Alley: Hernando, Hillsborough, and Pasco counties. The state's sinkhole problem is largely due to the soluble limestone base that lies beneath the ground's surface.What country gets the most sinkholes?
Why does China have so many sinkholes? While sinkholes can open up gradually or rapidly, sometimes swallowing buildings or vehicles and even causing deaths in China as well as in several areas around the US, the Chinese region of Guangxi has reported what may be the highest number of sinkholes found in a single area.Why does Mexico have so many sinkholes?
This is because the Yucatan Peninsula was once underwater - its soil is composed of limestone, formed from marine fossils; the conditions needed for cenotes to form. Furthermore, the Ring of Cenotes is an arc of sinkholes formed when a large meteorite struck the Yucatán Peninsula, 66 million years ago.Why does Fountain Minnesota have so many sinkholes?
Sturgis says sinkholes are a feature of what's called karst topography. It's when water and carbon dioxide form an acid that eats away the limestone, which is the bedrock most common in the area. It can also create caves and springs, which are common throughout Fillmore County.Where is the world's deepest sinkhole?
Deep in China's Fengjie County lies a natural wonder that has fascinated experts for decades. The Xiaozhai Tiankeng sinkhole is vast.Where is the biggest hole in the United States?
The deepest hole within the U.S. is the Bertha Rogers gas well in Oklahoma at 32,000 feet (6 miles) deep.What are the main causes of sinkholes?
Sinkholes are all about water.(This is called "weathering".) Water washes away the soil and residue from the voids in the rock. Lowering of groundwater levels can cause a loss of support for the soft material in the rock spaces that can lead to collapse.
What state does not have sinkholes?
Almost all 50 States within the United States (excluding Delaware and Rhode Island) have karst areas, with sinkhole damage highest in Florida, Texas, Alabama, Missouri, Kentucky, Tennessee, and Pennsylvania. A conservative estimate of losses to all types of ground subsidence was $125 million per year in 1997.Why is Florida full of sinkholes?
Sinkholes are a naturally occurring geological feature that is common in Florida. Much of our state sits on a bedrock of carbonate rock, primarily made of highly porous limestone. As water dissolves the limestone, it creates cracks and holes in the stone. The soil above then seeps down causing a pit to form.How many people have died in Florida from sinkholes?
While thousands develop each year, deaths and injuries from sinkholes are rare but not unheard of. A former University of Florida professor and contractor who has spent his career studying sinkholes told USA Today that he recalled only two other people in 40 years who have died because of sinkholes.What cities in Florida are known for sinkholes?

ORANGE COUNTY, Fla.According to the Orange County Regional History Center, the hourglass-shaped hole is roughly 150 feet around and is estimated to be 500 feet deep — perhaps even more. That's far deeper than other notorious sinkholes like Deep Lake or the 1981 Winter Park sinkhole.
Which area of Florida is most at risk for the sudden collapse of sinkholes?
In west-central Florida, the relation between the carbonate surface and the mantling deposits plays an important role in the circulation and chemical quality of ground water and the development of landforms. Sinkhole development depends on limestone dissolution, water movement, and other envi- ronmental conditions.
