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.

Russia's unprovoked war has killed tens of thousands, displaced millions, and the beautiful country of Ukraine is being destroyed. We cannot be silent even if the topic of this website has nothing to do with politics.
