Detailed explanation-1: -The combination of gravity, loss of buoyancy and water pressure can activate a collapse. By keeping water tables high, water conservation rules and drought restrictions are tools to help prevent sinkholes from occurring.
Detailed explanation-2: -The most dangerous type of sinkhole is a cover-collapse sinkhole. In these cases, the bedrock is covered by a layer of clay. Beneath this ground cover, however, water dissolves an underground cavern. Gradually, ground sediments begin to erode, or spall, into the cavern from the bottom.
Detailed explanation-3: -Stay away from and do not let children play near cliff edges and steep slopes, especially after heavy rains. Call your local police or public works if you see a slide or sinkhole. Do not enter caves or sinkholes that may collapse further or be filled with deadly poisonous natural gases.
Detailed explanation-4: -Cover Subsidence Sinkhole The last kind of sinkhole is known as Cover Subsidence Sinkhole. In this case, the hole is formed over a period of time. The bedrock here is covered by soil and materials which are not well knitted together.
