A new island has emerged out of the Pacific Ocean
A new island has been found in South Pacific. Earlier in the month, an underwater volcano erupted near Tonga. Due to this, lava was oozing and expelling steam and water above the surface. Hence there has been the formation of a new land mass which has quickly grown from one to more than eight acres. NASA Earth Observatory has also advised that a volcano on Home Reef seamount began to erupt on Sept 10. Eleven hours later, post the same, an unnamed island poked out of the water. Tonga Geological Services on Saturday had estimated that the island expanded to roughly 8.6 acres and stood at around 50 feet above sea level as on Sept 19.
The geological agency had advised that volcanic activities would be continued at Home Reef they posed a very low risk to the local Ha’apai and Vava’u communities.
It is not the first time that the Home reef has erupted. The region of submarine volcanoes flared up earlier, also in 1852, 1857, 1984, and 2006, which produced new islands each and every time. Islands created by underwater volcanic activity can exist for years, but they don’t last too long. There is also little hope that a little atoll southwest of Tonga’s Late Island could endure.
An island created by the nearby Late’iki’ Volcano in 1995 lasted for about 25 years. The space agency had advised that Home Reef is part of the Tonga- Kermadec subduction zone, where three tectonic plates are smashing each other and creating an active area for undersea volcanoes. A picture was launched by the NASA Earth Observatory, which revealed the volcanic eruption on Home Reef.
This news is kind of exciting for the geological team. Submarine volcanoes are the underwater vents or fissures in the Earth’s surface through which magma can erupt. Most submarine volcanoes are put up near areas of tectonic plate formation, which are also known as mid-ocean ridges. The volcanoes at the mid-ocean ridges are estimated to be 75% of the magma output on earth.
