Scientists have begun to explore the world's newest island, located just a few miles northwest of Tonga.

The land mass sits about 400 feet above sea level and was created after over a month of underwater volcanic activity that began in December 2014. Scientists say that continuing volcanic activity means the island probably won't be around for long, but in the meantime, locals are hoping it will spur tourism.

According to Mashable, fewer than a dozen people have been on the island. The island is mostly unexplored, but this man, who spent almost two weeks there, said the new landform "looks like a lunar landscape." He explored caves and beaches across the island and even found signs of life. Some pictures of his adventures are below:
