By 2010, Guatemala tiankeng

According to the us national geographic website reported, or because of the tropical storm &; ldquo O rdquo; add Sally of&" The influence caused by heavy rains, Guatemala capital Guatemala city downtown May 30 appeared a deep about 100 meters of the giant pit, let the world shocked. With strict geological terms to explain, tiankeng (sinkhole) it is to because water steady erosion solid bedrock, make the surface subsidence formed a huge happened''s pit. Many American places tiankeng chance are big.

Guatemala giant pit and tiankeng this term for further expansion, namely the earth suddenly collapsed. Guatemala city some urban ground not in solid bedrock above, but a layer of relaxation, constitute the volcanic pumice of rubble, usually with hundreds of feet thick. At least one geologists, said the latest tiankeng Guatemala city is triggered by pipeline leak, not natural phenomenon. Overall, Guatemala repeat more likely to occur again, but a very hard to predict.

In 2007, Guatemala city appeared a similar tiankeng, and distance recently appeared the tiankeng still far away. To photograph the judgment, the two tiankeng diameter is about 60 feet ($18 meters), deep about 300 feet (about 100 meters). Normally, the authorities would use large stone and other debris will tiankeng fill. Over time, in water erosion and air baked dry effect, still can cause tiankeng inward tilt.

In Florida, for example, wert parker tiankeng it and Guatemala tiankeng gradient is same, depth is about 100 feet (about 30 meters). But, Florida have &; ldquo Sunshine state rdquo; of&" The reputation and sunny, make tiankeng in about 24 hours slowly happen tilt. American Missouri state university geology waning lattice''s Gouzie) Doug uriah ze (say: &; ldquo I think Guatemala city tiankeng so rapidly and around and not collapse. & rdquo;

According to introduction glen parker, waitt uriah ze formed in 1981 tiankeng city a public pool below, &; ldquo As to the swimming pool leaks, I had never seen a complete report. & rdquo; He said, water can be through a crack on the bottom of the pool below the soil infiltration. Due to the Florida sand soil, even around the pool of aquatic plants may also will slowly enough soil erosion carried away, solid lime rock below. Lattice uzziah, points out that the usgs ze draws throughout the United States the bedrock type. Scientists are still need to underground cracks and flow of water through the cracks way extensive research, so that to happen tiankeng location prediction.

This deep approximately 185 feet ($56 m) tiankeng in 1994 appeared in Florida MaErBo in city, located in the place of mining subsidence occurred Agrico dump of enterprise IMC - a pile of scrap. The company was mining of phosphate rock to extract. Phosphate is a chemical fertilizers, is the main component, mainly used in the manufacture of phosphoric acid, and strengthen soda and various food tastes. However, in phosphate rock extracted from later, main component is gesso of waste materials are as mud filtered out.

With layers of gypsum is dry, they form a crack, like appeared in dry mud on the crack. Group Later, the water in the cracks in constant flow, will be gone for underground material, the formation of tiankeng create conditions. American regulators said IMC - Agrico company should be responsible for management of responsibility, avoid the tiankeng of underground water supply harm.

According to Missouri state university geologist lattice uriah ze introduces, in whatever place, want water erosion connection level drainage system of vertical channels, it could happen tiankeng, because in this case, a large number of solid matter be washed away. If tiankeng near the seashore or in the ocean & mdash; & mdash; Such as Honduras Belize coast lighthouse reefs famous &; ldquo Blue hole & rdquo; Tiankeng, seawater in collapse rapidly after infiltration, forming a bottomless pool.
