Most Dangerous Holes in the World

Jungles, oceans, and deserts are all synonymous with certain levels of danger. But what if I told you there are certain places in the world where huge holes reside, and one visit could end your life.

If you’re curious, stick around as we countdown the 15 most dangerous holes in the world.

BLUE HOLE RED SEA

The notoriety of the Blue Hole in Dahab as possibly the deadliest dive site on Earth doesn’t serve to keep divers away, but rather to attract them in the same way the challenge of climbing Everest or Kilimanjaro appeals to mountaineers.

When you dive the Blue Hole in Dahab, you have taken on one of the most challenging environments in diving and you will experience something truly remarkable.

This is why so many divers brave the 80-meter wide hole, despite the fact that many divers have lost their lives here. There is no official count, but it is said that at least 150 scuba divers lost their lives in the last 10 years.

One of the problems that lead to so many people falling foul when they plan the dive is that it really doesn’t seem that dangerous.

Unlike many other “extreme” diving sites, it is exceptionally easy to get to – it is a shore dive, right off the beach.

It can almost seem like the danger has been blown out of proportion when you see just how easy it is to enter and dive the Blue Hole.

Once there, there are no disturbing currents and the water is calm, clear, and temperate, but that doesn’t mean it’s not dangerous. Dive at your own risk!

GUATEMALA SINKHOLE

It was like something out of M. Night Shyamalan’s Signs. A gaping, perfectly circular sinkhole appeared in Guatemala City, devouring a three-story building and killing at least one man in the process.
The gargantuan cavity appears to be about 60 feet wide and 30 stories deep. If it wasn’t caused by aliens, how did the sinkhole form? Where did its insides go? And why the heck is it so round?
Sinkholes often appear in areas where the rock below the ground is limestone, carbonate rock, salt beds, or rocks that can be naturally dissolved by circulating groundwater. As the sediment dissolves, caves and air pockets develop underneath the land surface.
If there is not enough support for the land above the spaces, then the ground collapses and results in a sinkhole Natural depressions that collect water and man-made structures such as houses and streets with poor drainage are especially vulnerable to sinkholes.
Heavy rainfall, like that from Tropical Storm Agatha, only accelerates the process.
Where did all the material that used to be inside the hole go? Most of it is eroded and washed to the bottom of the hole long before the final collapse into an open hole.
When the hole opens, the surface material simply drops to the bottom. Why the heck is it so round? Holes often occur when the dissolution of bedrock results in a surface depression that collects water.
As the depression gathers more water, the water leaks downward and eats away at more bedrock, catalyzing its further dissolution. Eventually, a vertical, circular hole forms straight through the bedrock.
