Below is a summary of eruption dates and Volcanic Explosivity Indices (VEI).

The following references are the sources used for data regarding this volcano. References are linked directly to our volcano data file. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title. Additional discussion of data sources can be found under Volcano Data Criteria.

The Daisetsu volcano group (also spelled Taisetsu) lies at the northern end of the Daisetsu-Tokachi graben in central Hokkaido. It consists of a complex group of stratovolcanoes and lava domes associated with a small, 2-km-wide caldera. The eight satellitic volcanoes are aligned along a ring fracture that is centered over the eastern rim of the caldera. Asahi-dake, the highest peak of the complex, was constructed 3 km SW of the center of the caldera. Other stratovolcanoes are located along a NE-SW line cutting through the caldera that trends toward the Tokachi volcano complex to the SW. In contrast to the Tokachi group, no historical eruptions are known from Daisetsu, although the latest phreatic eruption took place sometime after 1739 AD. Fumarolic areas are located on Asahi-dake, where at one time sulfur was mined, and in the caldera.
