11. Great Blue Hole, Belize
Probably the Worlds most amazing sinkhole is the Great Blue Hole made famous by Jacques Cousteau. It is a large submarine sinkhole 60 miles off the coast of Belize. The hole is over 300m across and 125m deep. The Great Blue Hole formed as a limestone cave during the last ice age in the world over 150,000 years ago. As the ocean began to rise, the cave system flooded and eventually collapsed, creating a «vertical cave» in the ocean. It has unusual stilted stalactites and is part of the Belize Barrier Reef Reserve System, which has been declared as a World Heritage Site by UNESCO. Scuba divers frequent this reef because of the rare animal species and unique geological formations. The World has many Sinkholes but this might be the worlds biggest sinkhole in the world!
10. Dragon Hole, South China Sea
Deans Blue Hole in the Bahamas was thought to be the world’s deepest known underwater sinkhole. It plunges 202 meters down and widens considerably into a cavern making it a favorite among worlds professional deep-sea divers. The area is a tourist hotspot, and is home to a varied assortment of marine life. It’s also host to several World Championship diving events, including Vertical Blue, where more than 30 divers around the world compete in a series of free-diving challenges.
However, researchers just announced on July 22, 2016, that Dragon Hole is 300 meters deep, making it the deepest blue sinkhole in the world. Blue meaning filled with seawater. Experts said they had also discovered about 20 marine species in the cave and continue to study the hole. The World has many Sinkholes but this might be the worlds biggest sinkhole in the world!
9. Guatemala City Sinkholes, Guatemala
On February 23, 2007, out of the clear blue sky, this sinkhole collapsed killing five people and over 1000 were evacuated. The hole was over 100 meters deep and was the result of a corroded sewage system deep beneath the surface of the world that eroded the volcanic ash, limestone, and other soft minerals underlying Guatemala City. Citizens had hear rumblings a few weeks before but didnt know what it was. The hole was later filled in with soil cement and cost the Guatemalan government $2.7 million. Since the entire city is built on loose volcanic pumice and gravel, experts warned that it could happen at any time.
Just 3 years later in 2010, another giant sinkhole in Guatemala City swallowed a three-story factory, killing 15. Again, the sewer pipes played a role creating a sink hole that was 100 meters deep. Bad things come in threes and this along with Tropical Storm Agatha, and the Pacaya Volcano eruption made the government declare a state of emergency. Sinkholes are a dangerous reality for the people of Guatemala City and could happen anywhere in the city unless the government improves the citys runoff and waste water systems.

8. Siberian Holes
The three craters, one in Taymyr peninsula and two in Yamal, are believed to have been caused by huge underground gas explosions. Known by locals as the “end of the world”, the massive craters sparked endless theories about how they got there. The most famous crater — known to scientists as B-1 — was measured by echo-sounder this week and found to be over 60 meters deep, significantly more than previously thought. Discovered in 2014, it is located not far from Gazprom’s Bovanenkovo gas field in Russia’s northern Yamal Peninsula. The hole has been gradually filling up with water and is turning into a lake. The ring of dirt and debris around each hole indicates these massive holes were created by a force that stemmed from inside the Earth and exploded outward. Theories for the cause of these explosions include stray missiles, gas-related mishaps, pranks and, of course, extra terrestrial interference. The most likely explanation is that the holes are a kind of reverse sinkhole that has yet to be scientifically documented. Instead of collapsing in on themselves, it’s thought the holes were initiated by underground fissures that caused the melting of permafrost. The holes then filled with natural gas and, when the pressure became too great, dirt and debris erupted outwards.
