South-central Kentucky’s karst landscape is dynamic, with water and bedrock shaping the terrain. The area’s limestone foundation, part of the Western Pennyroyal geologic province, dissolves over time. This creates underground drainage systems and surface depressions called sinkholes. There are 703 documented cases of sinkholes in Allen County. Two main ways sinkholes form here. Collapse-type features […]
Northwest Florida’s unique geology creates underground cavities through limestone dissolution. Acidic rainwater speeds up this process. The area’s karst terrain, with porous bedrock, makes the ground unstable. A 2008 Florida Geological Survey study found over 112 subsidence events. Most happened near Crawfordville and coastal areas. Ground collapse patterns have emerged over the last 20 years. […]
North Florida is at high risk for sinkholes due to its karst terrain. The area’s limestone bedrock, shaped by water erosion, leads to sinkholes. The Florida Geological Survey reports over 66 sinkhole events here, with 18% not caused by karst. In 2012, a big sinkhole formed in McAlpin after Tropical Storm Debby. It was one […]
Central Florida’s unique geology brings natural risks due to its limestone-rich landscapes. The Florida Geological Survey’s 2008 sinkhole map shows 58 documented incidents in Volusia County. These incidents are mostly near DeLand, Deltona, and Daytona Beach. These areas have unstable terrain because of porous bedrock and shifting groundwater. Karst landscapes, with dissolved carbonate rock layers, […]
South-central Kentucky has a unique landscape with hidden underground voids. The area is part of the Western Pennyroyal karst zone. Here, water dissolves limestone bedrock, making the terrain unstable. Over millions of years, this has formed one of North America’s most dense sinkhole plains. Kentucky Geological Survey data shows 40% of the state has soluble […]
North Florida’s limestone-rich soil is perfect for sinkholes. There have been 52 documented sinkholes near Perry and Salem. These events follow the patterns of karst terrain, as shown by Florida’s geological surveys. Water underground slowly eats away at the limestone, creating holes. The Aucilla River basin is a great example. It has ancient cave systems […]
Northwest Florida’s unique geology makes it prone to ground instability. The area sits on top of porous limestone bedrock, formed over thousands of years. This bedrock is part of the Floridan Aquifer system that covers much of the state. The karst landscape is shaped by water dissolving limestone, sometimes causing sudden collapses. Recent data from […]
Northwest Florida’s unique geology makes the ground unstable. The area sits on porous limestone bedrock, typical of karst landscapes. Acidic groundwater dissolves these rocks, creating cavities that collapse under weight. Between 2008 and 2023, the Florida Geological Survey found 227 subsidence events. These include natural sinkholes and collapses caused by human activities. Researchers use soil […]
Central Florida’s limestone foundation is perfect for geological instability. The area sits on porous rock that dissolves slowly. This process creates underground cavities that collapse when too much weight is on them. The Florida Geological Survey says water table changes are key for surface collapses. Rainfall and human water use speed up erosion. Karst formations […]
