the coast of India North Sentinel is a part of the Bay of Bengal and the islands of Andaman and Nicobar

 the coast of India North Sentinel is a part of the Bay of Bengal and the islands of Andaman and Nicobar. Since it first became one of the deadliest islands in the world, it has been deadlier for a number of years. This is the reason it is lethal: 

1. Isolation with hostile natives 

• It is the home of one of the last uncontacted tribes in the world, namely, the Sentinelese people. They were cut off from the main world thousands of years ago and do not permit contact from the outside world. The individuals are very protective of their territory; they attack any outsiders who come near them. As a warning against, or in the assault of, other people, they use spears and arrows and other arms. 

•In 2006, the islanders murdered two accidental fishermen who had strayed to their island. The same year, a missionary who had made it his dream to reach the island to join them was murdered. 

2. Absence of Modern Immunity 

•The Sentinelese rarely interact with the outside world, and so are immunologically naive to most diseases that plague the average person. In case they run into outsiders, they could be exposed to influenza or measles, say, which could decimate their population entirely. The Indian government has, for this reason, enacted very strict laws to govern visits to the island, both as a safety measure for the visitors and the aborigines. 

3. Challenging Environment

Harsh Environment In addition to the danger posed by the natives, North Sentinel Island is also a very dense and forested land with few sites that would give way to survival by humans. 

It does not have safe anchorage, and shallow waters exist in the vicinity of the island, coupled with reefs, which are dangerous to approach through boats. 

Conclusion

North Sentinel Island is said to be the most dangerous place in the world, not because of the potential environmental risks but because of hostility by its residents, lack of immunity to diseases with which they are exposed, and access bans through law that make this island inaccessible to an outsider outside its boundary. It is such a place usually sealed in death in outsiders' attempts to reach it.
