Geological sinkhole.

2 days ago · Sinkholes are defined as a depression or hole in the surface of the earth due to the erosion of the underlying ground layer. Such sinkholes develop over time with a diameter ranging between 1 – 600m. Sinkholes can form on both land masses and ocean ground surfaces. They can have both, natural and anthropogenic (human made) causes.Sinkholes are a characteristic featuer of a karst terrain. In well-developed karst terrain, chains of sinkholes form what are known as solution valleys and streams frequently disappear underground. Sinkhole collapse, either slow or dramatic, can cause considerable damage to buildings, highways, rails, bridges, pipelines, storm drains, and sewers.A sinkhole is a closed natural depression in the ground surface caused by removal of material below the ground and either collapse or gradual subsidence of the surface into the resulting void. A pothole is usually a fairly small feature caused by failure of paving materials, usually associated with roads, parking lots, and airports.Apart from literature, history, and cinema, sinkholes are actually an important geological hazard in many parts of the world (Waltham et al., 2005; Parise and Gunn, 2007), involving mostly karst terrains but also affecting many urban centers, due to presence of cavities excavated by man in different epochs below the towns (for anthropogenic sinkholes, see later on).

Understanding Sinkholes. 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.

Article Vocabulary A sinkhole is a hole in the ground that forms when water dissolves surface rock. Often, this surface rock is limestone, which is easily eroded, or worn away, by the movement of water. In a landscape where limestone sits underneath the soil, water from rainfall collects in cracks in the stone. These cracks are called joints.Sinkholes (or dolines) are an often-overlooked environmental hazard. The processes that lead to their formation are slow and insidious, which encourage a lack of awareness or concern for the potential …
