The most dangerous islands of the Earth: diseases, snakes and aborigines with spears

According to scientists, on our planetMore than 500 thousand islands are located. Most of them are located near Japan, Indonesia, the Philippines, Norway and other countries. In our view, the islands seem to be paradise places where palm trees grow and exotic birds sing. However, in the world there are islands that you definitely would not want to visit. Having stepped on these patches of land, you can become infected with deadly diseases, become victims of predators and simply disappear for inexplicable reasons. But for what reasons did these islands become so dangerous places? In some cases, nature ordered it, but, for the most part, the islands gained notoriety through the fault of people. Let's look at some of the most dangerous islands on Earth and find out why they are considered such.

In the world there are islands in which it is better not to meddle


  • 1 Keymada Grandi Island
  • 2 Izu Archipelago, Miyakajima Island
  • 3 Bikini Atoll Island
  • 4 Gruinard Island
  • 5 North Sentinel Island

Kaymada Grandi Island

You have probably already heard about this island many times.have heard. Perhaps, without mentioning this “serpent's lair” not a single documentary about unusual places of our planet can do. Thousands of snakes of the species of island botrops (Bothrops insularis) live in an island located 35 kilometers from the coast of Brazil. The bite of these creatures up to 1 meter long causes tissue necrosis, gastrointestinal bleeding and other terrible consequences. Visiting this island is prohibited, but sometimes groups of tourists, accompanied by guides, come up to it.

Poisonous snakes were on the verge of extinction,but nature protected them in the most unusual way. Once the island was connected to the mainland, but rising sea levels led to the flooding of the "bridge". Island botrops cannot swim, so they are trapped. For a long time they actively multiplied and ate other animals, so now they occupy almost the entire area of ​​the island. Yeah, people with the fear of snakes about the existence of this island are better off not even knowing.

Izu Archipelago, Miyakajima Island

Near Japan there is a group of Izu islands,among which the most dangerous is Miyakajima. From 2000 to 2004, the Oyama volcano erupted on it, which threw toxic sulfur fumes into the air. These emissions occur to this day, therefore, special sensors are installed on the island, which include an alarm when the concentration of toxic substances in the air increases. If the inhabitants of the island hear a signal - they run to wear gas masks. After all, no one wants to inhale a poisonous substance that causes irritation to the eyes and respiratory tract, and then completely becomes a cause of clouded consciousness.

But why are people still living there? In fact, 3,000 people were evacuated at the beginning of the 21st century, but several years later some of them returned. And the matter is not only that their houses are located on a dangerous island. If you believe the Internet, then a certain scientific company pays money to "returnees" for the fact that they allow us to study the effect of sulfur on the human body using their example.

Bikini Atoll Island

The name of the Pacific islandBikini Atoll can be translated as “coconut spot”. There, people lived quite well, but in 1946, US authorities relocated them to neighboring islands. And all because they needed to test nuclear bombs. From 1946 to 1958, the military conducted 67 nuclear tests. For example, a bomb similar to the Fat Man was tested there, which in 1945 was dropped on the Japanese city of Nagasaki and caused the death of more than 80,000 people.

See the circles? They stayed from the bombs

In 1968, US authorities announced that the islandsafe to stay. However, all this was a lie - after returning home, about 840 people died from cancer. And this mass death is probably related to the consequences of nuclear tests. Despite the fact that more than half a century has passed since the terrible events, the plants growing on the Bikini Atoll are still dangerous. So it’s better not to visit this island.

There is excellent material on our site in which videos with nuclear explosions are embedded. Awful. But also beautiful.

Gruinard Island

On the territory of Scotland there is the island of Gruinard and itsfate was also very difficult. Nobody lived there, so researchers from the Porton Down military laboratory (England) decided to test biological weapons on it. In the middle of the 20th century, 80 sheep were brought to the island, after which aircraft dropped bombs filled with Bacillus anthracis bacteria on its surface, which spores cause anthrax. This disease affects the skin and may well damage the intestines and lungs - in general, a very deadly thing.

Disease killed animals and efficacybiological weapons have been proven - with such a bomb you can turn entire islands into deserts. For a long time, the soil of the island remained contaminated, but then scientists cleaned it well. At the moment, the island is home to some species of animals and they are completely healthy. But he still doesn’t take risks, and it is better to shun during travels of this island.

North Sentinel Island

A secluded island is located near ThailandSentinel, on which the warlike natives live. They do not want to contact anyone, so few have seen them. According to scientists, the Aboriginal society has about 400 people - it is believed that this is the last population of people that civilization has not touched. When trying to get closer to the island, people get rain from arrows and spears in response, because the aborigines do not want to let anyone near them. As a rule, all the guests of the island lose their lives - in 2006, the natives killed two Indian fishermen who came to the island by accident.

At the moment, humanity is not takingno attempt to contact the natives. When the island was damaged by an earthquake and tsunami, locals fired arrows at planes and boats. It’s really better not to go to them, not only because of the hostility of the Aborigines, but also for the benefit of their health. The fact is that the inhabitants of the island probably do not have immunity to diseases that are no longer considered dangerous to us.
