In the warm waters of the South Pacific, just southwest of the island nation of Tanga, an undersea volcano is making itself known. The eruption, about 39 miles north-west of the Tongan capital, Nuku'alofa, began on 16th March 2009, shooting clouds of smoke, steam and ash thousands of feet into the sky above the South Pacific ocean. The volcano, which is situated approximately six miles off of the main Tongan island of Tongatapu, is one of around 36 volcanoes clustered in a highly active volcanic region that represents a portion of the Pacific Ring of Fire.
