Last update: 12 Jul 2022 (Smithsonian / USGS Weekly Volcanic Activity Report)

Kita-Ioto (北硫黄島 officially Kita-iōtō, also frequently Kita-Iwo-jima, or Kita-iōjima, meaning "north sulfur island") is a steep-sided basaltic stratovolcano and forms a small island. It is the northernmost of the Kazan Retto (Volcano Islands) chain, in the center of the Izu-Maranas volcanic arc.
No historical eruptions have occurred from the deeply eroded Kita-Iwo-jima stratovolcano itself, but the Funka-Asane submarine crater, located about 2 km NW of the island was the source of the historical submarine eruptions, recorded since the 18th century and last in March 2022.
