Earlier this month, an underwater volcano close to Tonga erupted, oozing lava and expelling steam and water above the floor. It additionally fashioned a brand new land mass that is shortly grown from one to greater than eight acres in measurement.
In accordance with NASA’s Earth Observatory, a volcano on what’s often called the Residence Reef seamount started to erupt on Sept. 10.
Eleven hours later, the unnamed island poked out of the water.
On Saturday the Tonga Geological Companies estimated that the island had expanded to roughly 8.6 acres and stood at round 50 ft above sea degree as of Sept. 19.
The geological company stated “volcanic actions” had been persevering with at Residence Reef however that they posed solely a low threat to the native Vava’u and Ha’apai communities.
This is not the primary time Residence Reef has erupted. The area of submarine volcanoes flared up in 1852, 1857, 1984 and 2006, producing new islands every time.
Islands created by underwater volcanic exercise can exist for years, although they usually do not final lengthy, NASA stated.
However there’s hope the little atoll positioned southwest of Tonga’s Late Island may endure. An island created by the close by Late’iki Volcano in 1995 lasted for 25 years.
In accordance with the house company, Residence Reef is a part of the Tonga-Kermadec subduction zone, the place three tectonic plates are smashing into one another and creating an lively space for undersea volcanoes.
