The Red Lake sinkhole in Croatia. A sinkhole is a depression or hole in the ground caused by some form of collapse of the surface layer.
A sinkhole is a depression in the ground that has no natural external surface drainage. Basically, this means that when it rains, all of the water stays inside the sinkhole and typically drains into the subsurface. Sinkholes are most common in what geologists call, “karst terrain.”
Apr 24, 2014 · What: A sinkhole 2m wide appeared in the centre lane of Clementi Road towards West Coast Road, with one motorcyclist claiming that he fell into it and suffered minor injuries. Why: No reasons...
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.
What causes a sinkhole to form? They can be a life-threatening disaster—or a pricey nuisance. Here’s what you need to know about the depressions and holes that can form beneath our feet.
Dec 18, 2017 · Geologists classify sinkholes in three major types: dissolution, cover-subsidence, and cover-collapse sinkholes. But the truth is, we also have artificial sinkholes, caused by different human activities. Let’s have a detailed look at the most common types of sinkholes and what makes each different.
Sep 12, 2016 · In this article, we’ll discuss how to identify a sinkhole (including sinkhole detection and the most common signs of sinkholes), sinkhole inspection, and what to do once you’ve discovered a sinkhole.
Whilst the process of gradual dissolution can cause a sinkhole to form at the surface, other factors, including humans, can induce sinkholes to form. Heavy rain or surface flooding can initiate the collapse of normally stable cavities, especially those developed within superficial deposits .
Sinkholes are just one of many forms of ground collapse, or subsidence. Land subsidence is a gradual settling or sudden sinking of the Earth’s surface owing to subsurface movement of earth materials.
