Photo Gallery


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.
