November 15 , 2023 377 days 313 0
  • Recently, an undersea volcano eruption led to the creation of a new island near Japan's Ogaswara island chain.
  • The new island, which has not been named yet, is about 100 meters in diameter and was created due to phreatomagmatic eruptions.
  • It happens when magma comes into contact with seawater and creates explosive bursts of ash and steam.
  • Iwo Jima is an active volcano to the south of Ogasawara Island.
  • It is also about 60 km north of the Fukutoku-Okanoba underwater volcano.
