Sinkhole Basics

Why do sinkholes matter?

Like landslides, sinkholes can devastate small areas. Natural sinkholes are a potential threat throughout 20% of the United States.[1] Florida, Texas, Alabama, Missouri, Kentucky, Tennessee, and Pennsylvania are most sinkhole-prone because of their bedrock. Human-induced sinkholes can develop anywhere due to careless practices.
