- Sinkholes are naturally occurring geologic hazards that can cause voids/cavities to develop in the subsurface in regions underlain by Limestone/Dolomite geology. Once sinkholes develop, they can cause significant damage to property, pose safety threats, and are typically costly to repair.

What is a sinkhole hazard assessment & risk management?
Sinkholes can occur rapidly and apparently without warning. It is therefore important to consider the potential for sinkholes during planning (hazard susceptibility studies) and characterise them so that people can mitigate associated risks. Several processes can trigger sinkholes.
Three main concepts may be applied to reduce sinkhole risk: (a) avoiding sinkholes and sinkhole-prone areas (preventive planning); (b) diminishing the activity of dissolution and/or subsidence processes (hazard reduction); (c) incorporating special designs in the structures (vulnerability reduction).
Sinkholes form as a consequence of the recharge, through-flow and discharge hydrology of hydrogeological systems associated with soluble rocks and lead to karst (landscapes that result from the dissolution of soluble rocks).
Apr 8, 2024 · A sinkhole is basically a hole which appears to suddenly open up in the ground. However, the process that leads to a sinkhole is not so sudden and may have been developing...

Understanding & Managing Risks with Sinkholes. As the earth crumbles beneath your valuable property, managing sinkhole risks requires careful planning and responsive intervention to prevent potential disasters.
Mar 11, 2022 · Sinkhole is a ground that is formed by the collapse of the surface layer and has no external drainage. When it rains, the water stays in the sinkhole. Sinkholes can range from a few feet to hundreds of acres and less than 1 to 100 feet deep.
