Story highlights Central Florida is particularly known for sinkholes

The state lies on limestone bedrock and often sees the phenomenon

Florida property owners filed 24,671 claims for sinkhole damage from 2006 to 2010

Florida sinkhole claims cost insurers $1.4 billion in that period, state Senate report says

The kind of sinkhole that suddenly opened up under a Florida home is more common than you might think. Let's take a look at what causes them, where they happen and just how dangerous and costly they can be:

What causes sinkholes?

Many sinkholes form when acidic rainwater dissolves limestone or similar rock beneath the soil, leaving a large void that collapses when it's no longer able to support the weight of what's above, whether that be an open field, a road or a house. These are called "cover-collapse sinkholes," and it would appear this is what's happening in Florida, where the ground beneath the home suddenly gave way.

Where do they happen?

Sinkholes are particularly common in Florida, which rests on a nearly unbroken bed of limestone, according to the Florida Sinkhole Research Institute. Central Florida, including the Tampa area, is particularly known for sinkholes. In fact, Hillsborough County, where Thursday's collapse occurred, is known as part of Florida's so-called Sinkhole Alley, where two-thirds of insurance claims for sinkhole damage occur, according to a report prepared for state lawmakers in 2010. Other places that frequently see sinkholes include Texas, Alabama, Missouri, Kentucky, Tennessee and Pennsylvania, the U.S. Geological Survey says.

Do all sinkholes collapse so dramatically?

No, some merely cause the ground above to sag, or result in small ponds or saltwater marshes, the Florida Department of Environmental Protection says.

How often do they happen?

There do not appear to be any solid numbers, but the Florida Senate Committee on Banking and Insurance reported that insurers had received 24,671 claims for sinkhole damage in that state alone between 2006 and 2010. That's an average of nearly 17 claims a day, just in Florida.

How dangerous and costly are sinkholes?

Deaths and injuries from sinkholes are rare, but certainly not unheard of. For instance, in 2012, a 15-year-old girl died when her family's car fell into a Utah sinkhole, according to media accounts. But the holes are enormously costly. Insurance claims submitted in Florida alone between 2006 and 2010 totaled $1.4 billion, according the Florida Senate report.
