The Global Volcanism Program has no Weekly Reports available for Kita-Ioto.

The Global Volcanism Program has no Bulletin Reports available for Kita-Ioto.

No historical eruptions have occurred from the deeply eroded Kita-Ioto stratovolcano, which forms a steep-sided basaltic cone rising 792 m above the sea. However, eruptions have been recorded since the 18th century from Funka Asane, a submarine vent 4-5 km NW of the island. Kita-Ioto is the northernmost of the Kazan Retto (Volcano Islands), located in the middle of the Izu-Marianas arc.

Kita-Iwo-jima is seen from a ship west of the island. No historical eruptions have occurred from the deeply eroded Kita-Iwo-jima stratovolcano, which forms a steep-sided cone rising 792 m above the sea. However, eruptions have been recorded since the 18th century from Funka-Asane, a submarine vent about 2 km NW of the island. Kita-Iwo-jima ("North Sulfur Island") is the northernmost of the Kazan Retto (Volcano Islands), located in the middle of the Izu-Marianas arc.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
