According to Xinhua News Agency report: A submarine volcano in the sea between New Zealand and Tonga erupted a few days ago. A large amount of magma and volcanic ash erupted from formed an island with an area of 24,000 square meters.
According to CNN local time on the 24th, local time, citing NASA information, the undersea volcano called "Hom Reef" erupted on September 10. 11 hours later, a small island formed by magma and volcanic ash emerged from the sea. The NASA Earth Observatory issued a statement saying that the satellite captured images of the island.
The island is located in the northeast of the volcano of Hongaha Apai Island, which had a violent eruption at the beginning of this year. It grew rapidly after its formation. The area was about 4,000 square meters on the 14th, and by the 20th, it had increased to 24,000 square meters.
statement said that islands formed by undersea volcanoes are often "short-lived" and can occasionally exist for a long time. An island formed in 12 days after an eruption of a sea volcano near the "Hom Reef" was washed away two months later, while an island formed in 1995 only disappeared 25 years later.
Tonga Geological Services said that as of the 23rd, the "Hom Reef" was still erupting, but volcanic activity poses a lower risk to air transport and residents of nearby islands. The agency recommends that before receiving subsequent notice, the ship must maintain a distance of more than 4 kilometers from the "Hom Reef" volcano.
