Sinkholes and insurance

Sinkholes-- depressions in the surface area of the ground brought on by the unexpected settlement or collapse of the land-- are a natural component of the landscape in lots of states. While the risk of a sinkhole is low, the fallout is possibly devastating to a house owner.

How are sinkholes formed?Sinkholes tend to form in locations where underground water materials, such as from an aquifer, liquify rock-- normally limestone. Moving water dissolves percentages of rock and brings it away, which increases the size of natural pores and cracks in the bedrock. In time, as more and more limestone breaks down, large cavities and caves form. When the land surface gives way to fill in the voids, a sinkhole occurs.No one understands for certain where or when a sinkhole can happen

, however there are contributing aspects that make them most likely to develop, such as building in susceptible locations and falling water tables. Dry spell conditions-- or droughts followed by sudden rains-- can trigger the limestone to shift, which increases sinkhole activity.Sinkhole threat Sinkholes are discovered all over the world. In the United States, sinkholes are specifically common in Texas, Alabama,

Missouri, Kentucky

, Tennessee, Pennsylvania and Florida, according to the United States Geological Survey.
