TONGA – JULY 10: (AUSTRALIA & NEW ZEALAND OUT) Journalist, Peter Munro, stands in a cave on the newest island on Earth, July 10, 2015. It emerged from the waters of the South Pacific in January 2015 when a volcano erupted on the nearby island of Tonga, forcing pulverised magma into the air above the ocean. The magma gradually built up on the ocean floor, penetrating the surface of the water to form the island. (Photo by Edwina Pickles/The Sydney Morning Herald/Fairfax Media via Getty Images)
