What is the cause of sinkholes in Florida?
The main trigger for sinkholes is water—too much of it, or too little. The normally moist soil of Florida has a stabilizing effect on karst. But during a drought, cavities that were supported by groundwater empty out and become unstable.
Where are sinkholes most common in Florida?
Sinkholes can form anywhere in Florida, but the highest activity level occurs in west central Florida because of the karst limestone environment. There are several influences that increase the risk of sinkhole activity such as long-term weather conditions, heavy acidic rains, and drought-like conditions.
What parts of Florida are prone to sinkholes?
Sinkhole Alley: One of the Worst Sinkhole Areas in Florida
The area is primarily made up of Pasco and Hernando counties – the leading counties in reported sinkholes. Spring Hill, located in Hernando County, made national news in 2014 when a sinkhole swallowed up a neighborhood street.
Why is Florida more prone to sinkholes?
Conversely, when sinkholes become plugged, they can cause flooding by capturing surface-water flow and can create new wetlands, ponds, and lakes. Most of Florida is prone to sinkhole formation because it is under- lain by thick carbonate deposits that are susceptible to dissolution by circulating ground water.
What is the biggest sinkhole in Florida?
Winter Park Florida Sinkhole of 1981.
How dangerous are sinkholes in Florida?
Florida’s geological landscape makes to presence of sinkholes more common than most homeowners would like. Sinkholes are not only dangerous but can cause devastating property and home damage – making Florida sinkhole coverage a must-have for many Florida homeowners.
Occasionally a sinkhole may exhibit a visible opening into a cave below. 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.
Which state has the most sinkholes?
“The most damage from sinkholes tends to occur in Florida, Texas, Alabama, Missouri, Kentucky, Tennessee, and Pennsylvania.”
How can we prevent sinkholes in Florida?
Use water sparingly if you live in an area with frequent droughts. Underground aquifers often help to prevent sinkholes because the water fills in cracks and holes that would normally cause settling. If the water isn’t present, the soil and rocks have more space to move and cause sinkholes.
Is Florida sinking?
Yes, the land is slowly sinking in parts of Florida, but the sea is rising much faster and poses a far greater threat of flooding.
Where is sinkhole alley located in Florida?
Sinkhole Alley is located in the counties of Pasco, Hernando and Hillsborough in the west central area of Florida. It accounts for more than two-thirds of sinkhole insurance claims between 2006 and 2010.
Are sinkholes covered by homeowners insurance in Florida?
Florida has more sinkholes than any other state in the nation. However, not all homeowners‘ policies provide coverage for damage to your home resulting from sinkholes. Florida law only requires insurance companies to cover “catastrophic ground cover collapse.”
What is the largest sinkhole in the world?
The vast Qattara west of Cairo, Egypt is the largest natural sinkhole in the world, measuring 80km long by 120km wide. This dangerous, sludge-filled quicksand pit is unearthly in its appearance and shocking in its size.
Where do sinkholes occur most often?
The USGS calls areas like this “karst terrain.” According to the USGS, about 20 percent of U.S. land is susceptible to sinkholes. The most damage from sinkholes tends to occur in Florida, Texas, Alabama, Missouri, Kentucky, Tennessee, and Pennsylvania.
How can we prevent sinkholes?
The combination of gravity, loss of buoyancy and water pressure can activate a collapse. By keeping water tables high, water conservation rules and drought restrictions are tools to help prevent sinkholes from occurring.
