Daisetsu VulkanDaisetsu (also spelled Taisetsu) volcano is a group of 8 stratovolcanoes, lava domes and a small 2 km wide caldera in the Daisetsu-zan National Park (the roof of Hokkaido) in central Hokkaido.
Asahi (旭岳 Asahi-dake) volcano is the highest peak of the volcanic complex and the highest mountain in Hokkaido.
No historical eruptions are known from Daisetsu, although the last eruption must have taken place in or after 1739 AD. At present, there are fumaroles and sulfur was mined at Asahi-dake.
Daisetsu-zan National Park is the largest national park of Japan covering 230,000 ha. The park stretches from Mt. Torashiumu to the Tokachi Mountains. It is known for its hot springs, which can be found at Sounkyou, Yukomanbetsu, Tenninkyou, Nukabira, Shirogane, Shikaribetsu and Tomuraushi.
Beschreibung:The Daisetsu volcanic group formed at the northern end of the Daisetsu-Tokachi tectonic graben. Several vents are aligned along a ring fracture over the eastern rim of the caldera and on a NE-SW line cutting through the caldera and trending towards the Tokachi volcano complex to the SW.
