Banua Wuhu is a submarine volcano that rises more than 400m (1,300feet) from the sea floor in the Sangihe Islands of Indonesia. Historical records show that several ephemeral islands were formed and disappeared. A 90m (300feet) high island was formed in 1835, but then dwindled to only a few rocks in 1848. A new island was reportedly formed in 1889 and it was 50m (160feet) high in 1894. Another new island was formed in 1919 but then disappeared by 1935.[1]
