NASA experts believe that as a result of the underwater eruption of the volcano, a pumice raft "the size of Manhattan" was formed. Simon Boxal, a senior lecturer at the National Oceanography Center, also claims the huge mass could cause "Great Barrier Reef" damage. The pumice tree could also save the Great Barrier Reef by helping to "re-sow" the dying coral reef. The Great Barrier Reef is dying at an astonishing rate with a 50 percent drop in coral coverage between 1985 and 2012, according to the Barrier Reef Foundation.
He told Sky News: "As it moves north, it is estimated that it may take a month or two to reach Fiji.
"But at the moment the thought is from the Technical University of Queensland that when the raft moves on, it moves around the currents towards the Great Barrier Reef.
"One hope is that it does, this material for shelves on the surface begins to gather marine life, things grow on it, in the same way that algae grow on boats left alone in the water.
"So they will receive polyps that form like the seeds of a reef. So the hope is that these coral reef seeds will eventually target Australia and could help re-plant parts of the Great Barrier Reef that are dying.

"Now there is a downside to this, and the downside is that the salad material can carry other species that can cause damage. Time will tell if this is a good or bad thing about the Great Barrier Reef. "
Earlier in an interview, Sky News presenter Kay Burley said," Sailors are being warned to look after Tonga after pumice rafts the size of Manhattan formed in the ocean.
"A huge mass has been sailing in the Pacific for two weeks, but scientists are still arguing exactly where it came from. NASA experts believe the raft is the result of an underwater volcanic eruption. "
Mr Boxall further explained:" Pumice is formed when you undergo a volcanic eruption. The molten rock, which is incredibly hot as it exits the earth, releases pressure.
"They swim and form this enormous raft of more than 1
NASA stated that the volcano erupted for the first time since 2001.
NASA's Earth Observatory writes: "On August 13, 2019, Landsat 8's Operational Land Imager acquired the natural color of a huge pumice stone floating in the tropical Pacific near Lat Island in the Kingdom of Tonga.
"NASA's Terra satellite discovered the mass of a floating rock on August 9; the bleached water around the pumice stone indicates that the submarine's volcano is somewhere below.
'By August 13, the lard was sailing southwest. By August 22, the raft had moved north again and was a little more scattered, but still visible. “
