Shiretoko-Iwo-zan VulkanShiretoko-Iwo-zan volcano is an active stratovolcano on the NE tip of Hokkaido on the Shiretoko Peninsula. It is known as one of the many Japanese "sulfur mountains". During eruptions in 1936 and 1889, the volcano erupted molten sulfur.
The Shiretoko Peninsula was declared a Unesco World Heritage Site in 2005.
Beschreibung:Shiretoko-Iwo-zan is an andesitic stratovolcano with 2 large craters at the summit breached to the NW. The southern crater contains a small flat-topped lava dome. The main cone, Naka-dake, was built NW of the headwalls of the 2 summit craters. Historical eruptions have originated from the southernmost of 3 explosion craters along a NNE-SSW line on the NW flank of the main cone of Shiretoko-Iwo-san.
