North Central Florida has the perfect mix for sinkholes. The area is built on carbonate bedrock, like limestone, formed from old sea deposits. This rock slowly dissolves as groundwater moves through it, a process called karst dissolution. The Florida Geological Survey found that rainwater’s acidity speeds up rock erosion. As time goes on, underground spaces […]
Northeast Florida’s unique geology poses natural hazards beneath its surface. The area sits on porous carbonate rock layers, affecting land stability. Between 1998 and 2008, there were 72 subsidence incidents in Jacksonville and nearby areas. Recent studies show a link between these incidents and human and natural activities. Urban areas, like those near Baldwin’s limestone […]
Central Florida’s unique geology makes it prone to ground collapses. The area sits on porous limestone, formed from ancient sea deposits. This karst landscape dissolves when acidic rainwater flows through, creating underground cavities. As these cavities grow, the ground above loses support. This can lead to sudden collapses when the ground can’t hold its weight. […]
Southwest Florida’s unique geology makes it vulnerable. The area sits on karst terrain, where limestone bedrock dissolves slowly. This creates cavities that can collapse without warning, posing risks to infrastructure and residents. USGS records show recurring ground instability in the area over the past 20 years. At least 12 notable collapses happened between 2004 and […]
North Florida’s unique geology brings natural risks to Hamilton County. The area sits on porous limestone bedrock, known as karst topography. This makes it prone to erosion. Over two decades, changes in groundwater and surface conditions have caused many subsidence incidents. State geological surveys found 519 square miles of ground instability here. These events can […]
North Florida’s landscape often deals with underground voids. The area between the Apalachicola and Ochlockonee Rivers has porous limestone bedrock. This makes it prone to ground collapses, affecting places like Gretna and Oak Grove. The Florida Geological Survey has found the region to be at high risk. The 2008 FCIT sinkhole map gives some insights, […]
Florida’s limestone bedrock is perfect for sinkholes, like in Columbia County. This area is in a karst terrain. Acidic groundwater dissolves the rock over time, creating underground spaces. These spaces can collapse, causing sudden ground drops. The Florida Geological Survey uses advanced maps to spot these areas. They tell natural sinkholes from ones caused by […]
North Florida’s Big Bend is known for its active sinkholes. This is due to porous limestone bedrock covering 1,026 square miles. The rock slowly dissolves, creating holes that collapse under weight. Coastal erosion and seasonal water changes speed up these events in some spots. The Florida Department of Environmental Protection watches these changes closely. They […]
North Florida’s karst landscape poses unique geological risks. The area’s porous limestone bedrock, shaped by millions of years of water erosion, is prone to sudden ground collapses. In December 2024, a residential property near Old Town experienced a collapse without warning. Geologists say these events are caused by limestone dissolving in the Floridan Aquifer System. […]
