Fukutoku-Okanoba

Fukutoku-Oka-no-Ba

Cono piroclastico · Japan · 29 m (sottomarino)

Fukutoku-Oka-no-ba is a submarine volcano located 5 km NE of Minami-Iwojima island (right). Water discoloration is frequently observed near the volcano and several ephemeral islands formed in the 20th century. The first of these created Shin-Iwojima in 1904, and the island seen in this 21 January 1986 photo; wave erosion removed the island by 8 March.

Sintesi geologica

Fukutoku-Oka-no-ba is a submarine volcano located 5 km NE of the island of Minami-Ioto. Water discoloration is frequently observed, and several ephemeral islands have formed in the 20th century. The first of these formed Shin-Ioto ("New Sulfur Island") in 1904, and the most recent island was formed in 1986. The volcano is part of an elongated edifice with two major topographic highs trending NNW-SSE, and is a trachyandesitic volcano geochemically similar to Ioto.
