1. Qattara Depression
He Qattara, west of Cairo, Egypt, the land there is the largest sinkhole in the world that leave a big hole with a length of 175 km and width 90 mil/280 mil/140 km. Location lost here like the earth and its size is very surprising.
Most parts of the hole that it was 134 feet below sea was never used in war and later the scientists are trying to build projects worth 360 million dollars (3.8 trillion), which utilizes Qattara to complement the availability of energy independent. This plan requires that trenches dug from the Mediterranean to the Qattara edge so water will drain hole through the tunnel. In the end (at least 160 years ahead) the new lake will rival the size of Lake Eerie, where the desert heat will evaporate additional water flow. Egypt is a land where a number of sinkhole in the desert. But most can not understand is 100% natural phenomena in this Qattara hole. Qattara is the result of wind erosion or storm winds that eroded the top layer until the sinkhole into the source of the water layer.
2. Berezniki
Berezniki holes on the Russian began to appear in 1986 and continued to sink every year without stopping. When this has reached a depth of 200 meters by 80 meters long and 40 meters wide. If anyone has ever heard Berezniki may know this is where suppliers of the world will need 10% Potash (potash / potassium carbonate) and the hole was threatening railroad lines in the area of mines.
3. Guatemala City
Occupants in Guatemala City one time ever heard a strange rumbling for weeks but was not sure what's really going on around them. Then in late February 2007, the earth where they stand a sudden sinkhole to earth! A hole that is almost a perfect circle is created in real time by bringing all the existing as well as above it includes approximately 1000 of the human who later successfully evacuated. Two of them died. This disaster caused by the collapse of irrigation systems under the ground surface.
Holes are created due to geological conditions change due to errors of maintenance of irrigation systems and underground pipes that have been aging, but the general factor common cause is water. Earth rests on carbonate rock layers will be exposed to erosion due to continuous water flow. It would be eroded and the rock layers will be filled with water and eventually creating sinkhole-prone state.
4. Sarisarinama
Sarisarinama holes in Venezuela this is a natural wonder of the mysterious and beautiful. There are several circular holes that reach 350 meters in diameter and a depth of more than 350 meters. Scientists are not sure how the holes are formed at first.
Each hole has a unique ecosystem with many plants and animal species that does not exist in the other hemisphere.
5. Bimmah
Bimmah is the name of one of the location of strange natural phenomenon that is awesome. Residents here, Oman, making this a big hole as tourist attractions (more precisely, garden or swimming pool).
6. Mount Gambier
Known as the city of craters, Mout Gambier (located Among Adelaide and Melbourne in Australia Southeast) have a lot of interesting things such as lakes, caves, and holes in the ground. The city has both the volcanic craters and large holes that contain water, so naturally make this city beautiful.
7. Rumah yang Kurang Beruntung di Florida
Steve Kluge made a list of interesting pictures relating to the geology and natural disasters. This is the house the less fortunate and drowned in Florida. Land sinkhole is one of the classic problems in Florida in addition to floods and storms.
8. Agrico Gypsum Stack
Florida has long been haunted by a landslide soil sinkhole, but the disaster this one is one of the greatest. Land of the sinkhole is located beneath the gypsum stack (toxic industrial waste) as much as 80 million tons. These hazardous materials contaminating the drinking water 90% in Florida and efforts costing millions of dollars cleaning. Hole 2 million cubic feet of volume, is later given the name "Journey to the Center of the Earth" and is known as one of the objects of entertainment from Disney World products.
9. South Florida
Karst (a type of rock layers) in one city in South Florida has decreased and produces a hole in the ground big enough.
10. Lubang Bumi Setan
The depth is pretty "horrible" that reached 400 feet, this is the "devil hole" in Texas. Mouth hole, measuring 40 x 60 feet and there is archaeological evidence that this place was sacred by Native Americans. Locals used to find the arrows, stalactites, and other treasures from this big hole.
11. Macungie
Water content is actually help "save" the land of our footing, if not, of course we can not build anything on it because it will easily eroded. However, if the soil has become a big water trap, the stakes are sinkhole. If the soil is naturally sinkhole may be excused even create a lovely natural wonder, but if it is caused by man himself, of course, very bad consequences. Macungie Amblesnya land in Pennsylvania in the making Florida a big loss. In Pennsylvania under the soil water system is aging and sinkhole phenomenon becomes common ground.
12. Bowling Green
Construction plans trimodal Kentucky Transpark immediately canceled the event of land 200 feet wide sinkhole in Bowling Green, Kentucky. In this region is indeed known sinkhole-prone land and any time something like this could happen again. This makes development around the area here is very risky.
In Daisetta, Texas has recently (May 2008), which preceded by 20 feet wide amblesnya land in a residential area, be extended up to 900 feet with a depth of 100 feet in a day and swallowed the telephone poles, buildings and vehicles. Local authorities have investigated the possibility of leaks on lines of oil and natural gas there. Sediment and sludge oil generated also endanger lives a few houses nearby.
14. his damaged Montrose Avenue
Land sinkhole 80 feet wide with a depth of 15 feet occurred in the middle of Montrose Avenue. This road was finally closed during the two weeks in early January last year. Fortunately no casualties because of this incident.
