How many sinkholes open up in a year?
There is no database of sinkhole collapses for the United States, so these data are unavailable. Some individual state geologic surveys track reported collapses within their state. Many sinkhole collapses are not reported to authorities or news organizations, and many occur in rural areas where they are unobserved.

Karst in the United States: a digital map compilation and database
This report describes new digital maps delineating areas of the United States, including Puerto Rico and the U.S. Virgin Islands, having karst or the potential for development of karst and pseudokarst. These maps show areas underlain by soluble rocks and also by volcanic rocks, sedimentary deposits, and permafrost that have potential for karst or...

Sinkholes
Sinkholes are a common feature in Missouri where limestone and dolomite outcrop. Though often considered a benign nuisance, sudden, catastrophic collapses can destroy property, delay construction projects, and contaminate ground water resources.

Land subsidence in the United States
This report explores the role of science in defining and understanding subsidence problems, and shows that the optimal use of our land and water resources may depend on improved scientific understanding to minimize subsidence. More than 80 percent of the identified land subsidence in the Nation is a consequence of human impact on subsurface water...

Exploring caves: teaching packet for grades K-3
"Exploring Caves" is an interdisciplinary set of materials on caves for grades K-3. Caves entail at least five scientific disciplines: earth science, hydrology, mapping, biology, and anthropology. Each of these disciplines involves a unique content area as well as the development of particular intellectual skills. This unit aims at helping...

Development of sinkholes resulting from man's activities in the Eastern United States
Development of induced sinkholes in carbonate terranes in the Eastern United States has resulted in costly damage and water pollution. Previously, detailed investigations of sinkholes were limited to Alabama and Missouri, with the most comprehensive being in Alabama. An investigation of the remainder of the area was made in 1981 to regionalize...

An Unseen World Beneath Our Feet - Caves, Sinkholes and Springs
Randall Orndorff, Director of the Eastern Geology and Paleoclimate Science Center, discusses how Karst affects daily life. Beneath a quarter of the United States are rock types that can dissolve to form caves, sinkholes and other features. Nearly every state has rock layers of limestone, gypsum, and other soluble rocks we call ‘karst’. Karst is important for many reasons.

Karst features, Buffalo National River
Examples of karst features within the Buffalo National River Park. Karst is a type of topography that is formed over limestone, dolomite, or gypsum by dissolving or solution, and that is characterized by closed depressions or sinkholes, caves, and underground drainage (American Geological Institute Dictionary of Geologic Terms).
Sinkholes in West-central Florida, Freeze Event of 2010
More than 110 sinkholes formed in the Dover area of Florida during a freeze event in January 2010. Ground water levels dropped to record-setting lows as farmers pumped water to irrigate their plants for protection from the cold temperatures. The sinkholes destroyed homes, roads and sections of cultivated areas.
