Although the earth is 4.543 billion years old, it has not yet completed its formation, it is not completed, and this time we are “surprised” by a new island.
On September 10, after 16 years of deep hibernation in the southwestern Pacific, a dormant underwater volcano awoke and began spewing lava, according to NASA’s Earth Observatory.
The Tonga Geological Service reported that the new island continued to grow until September. 20, approximately 24,000 square meters (6 hectares). https://t.co/3GrKsNRkdh

The volcano is located on a seafloor ridge that stretches from New Zealand to Tonga, which has the highest concentration of underwater volcanoes in the world.
Eleven hours after the volcano erupted, a new island rose above the water as debris slowly piled up across the new island and grew over several days.

Home Reef, an underwater volcano in the Pacific Ocean southwest of Vava’u in Tonga, created a new island by spewing clouds of steam and ash, sending chunks of lava and rock, and changing the color of the surrounding water.
“An underwater volcanic eruption pushed an island off Tongadaily beneath the waves to about 10 meters above sea level.
Scientists say the island grew from 1 acre to nearly 6 acres in just 5 days following the Home Reef Volcano eruption” https://t.co/AQLSQOu78j— to Lord Fusitu (@LordFusitua) September 21, 2022

The Operational Terrain Imager-2 (OLI-2) captured a colorful view of the young island on September 14, and the device is a sensor on the Landsat 9 satellite.
According to NASA, previous research has shown that plumes of superheated acidic seawater contain particles and fragments of volcanic rock and sulfur.
Researchers at Tonga’s Geological Service estimated the island’s area at 4,000 square meters (1 acre) above sea level and 10 meters (33 feet) above sea level on September 14.
On September 20, the island grew to 24,000 square meters (6 acres).
“The volcano poses a low risk to aviation and residents of Vava’u and Hapai. However, all sailors are advised to travel more than 4km from Home Reef until further notice,” Tonga Geological Services said in an update published on September 20. ” Said.
