When the tsunami struck the Indian Ocean, the Indian government (which governs the island in name only) assumed that the Sentinelese were all killed but a helicopter survey spotted several of them on the shoreline.

This coupled with the remote location of the island makes it one of the last remaining unexplored places on Earth. Most encounters in the past with the tribe has led to violence. Their use of metal tools is limited to what they salvage from shipwrecks. They live as hunter-gatherers and there is little to no evidence of them controlling fire or engaging in agriculture. Very little is known about them and estimates of their population vary from 70 to 500, but we do know that they are perhaps the last Paleolithic culture left on Earth. It is home to the Sentinelese people, one of the most remote and primitive tribes left on Earth. This island is noteworthy for another reason. North Sentinel is a part of the Andaman Island chain, which was one of the first places to be hit by the earthquake and the ensuing tsunami. This is a large coral reef, which was permanently raised out of the ocean several meters by the uplifting of the Burma plate. Note the light colored ring around the island in the second image. No, this is not an example of a very strong tide but instead it is a visible reminder of the terrible power of the 2004 Indian Ocean earthquake and tsunami. Both images are of the same place, North Sentinel island in the Indian Ocean, but they were taken a few years apart.
