Although the earth is 4.543 billion years old, it is not done reinventing itself; this time by adding a whole new island.
On September 10, a dormant underwater volcano in the Southwest Pacific awoke and began seeping lava, according to Nasa’s Earth Observatory.
The volcano sits on a seafloor ridge stretching from New Zealand to Tonga and has the world’s highest density of underwater volcanoes.
Eleven hours after the eruption began, a new island rose above the water’s surface.
The Home Reef seamount volcano in the central Tonga Islands ejected plumes of steam and ash, discoloring the surrounding water.
Landsat 9’s Operational Land Imager-2 (OLI-2) captured a natural color view of the young island on Sep 14.
According to Nasa, previous research indicates that the plumes of overheated, acidic seawater contain particulate matter, volcanic rock fragments and sulfur.
Researchers from the Tonga Geological Services estimated the island’s area at 4,000 square meters and its elevation at 10 meters (33 feet) above sea level on September 14.
By September 20, the island had grown to 24,000 square meters.
“The volcano poses a low risk to the aviation community and residents of Vava’u and Ha’apai,” the Tonga Geological Survey said in an update released Sept. 20.
‘However, all seafarers are advised to sail further than 4 kilometers from Home Reef until further notice.’
