1.Guatemala sinkhole
In 2007, Guatemala became one of the biggest holes in the world. At first they believed that the hole has been a consequence of rainfall during tropical storm Agatha. Then they discovered that the hole was caused by humans. According to Sam Bonis, a geologist at Dartmouth College in New Hampshire, who is currently living in Guatemala City, an explosion in the sewer pipe may be made concave cavities underground. Sinkhole in Guatemala City, an estimated 18 meters (60 feet) wide and 100 meters (300 feet). Infrastructure built in the city in which several hundred meters underground mostly made of a material called pumice lightweight, precipitated from the volcano eruption This disaster killed two people and left thousands injured.

3. Darvaza Gas Crater - The Door to Hell
Derweze is a Turkmenistan village of around 350 inhabitants, located in the Karakum desert, about 260 km north from Ashgabat. Derweze area is very rich in natural gas. In 1971, a drilling rig (drilling equipment) Soviet accidentally punched into an underground cave to attract large-scale gas, but instead it is actually causing the ground to collapse and the entire drilling rig fell in. Darvaza Gas Crater or the "Door to Hell" which produce a hole of about 328 feet. Holes burned directly, continuously, for 38 years, until now experts can not predict when the fire will be extinguished.

4. The Great Blue Hole
Great Blue Hole is a large drain off the coast of Belize. This hole is a remarkable creation of nature. Great Blue Hole is one of the most famous natural wonders of the world list. This hole in the believe is the world's largest hole in the estimate laut.lubang It has a depth of approximately 125 meters and a diameter of about 300 meter.Telah spawned by rising sea levels about 65,000 years lalu.hal was formed during several episodes of Quaternary glaciation, when the water level the distant sea is still lower than the surface of the hole. Analysis of stalactites found in Great Blue Hole shows that formation has occurred 153,000, 66,000, 60,000, and 15,000 years ago. then the next episode of sea water began to rise and the caves began to flood.

5.Kimberley Diamond Mine, South Africa
Kimberley is a city in South Africa and capital of the Northern Cape. It is located near the confluence of the Vaal and Orange. Kimberley Big Hole is famous for, which is also considered the deepest hole in the world recognized. Originally the hole was as deep as 240 meters, mine has small holes underground in the mine to a depth of nearly 1097 meters but now after being abandoned, the hole was widely used to remove debris. The mine was closed in 1914. Around the year before 1871 to 1914, 22.5 million tons of soil dipindahkan.Saat, the Big Hole depth of about 215 meters remaining, minus 40 yards from the water level, until the hole was seen leaving only about 175 meter.Kita should know that this hole unearthed only with the usual equipment such as rakes, shovels, hoes etc.
