Geological summary

Akandanayama is located NW of Abo Pass in south-central Honshu. It is a stratovolcano composed of a lava dome, lava flow, and pyroclastic deposits. Shirataniyama volcano and the active Yakedake volcano are to the N. Volcanic activity began with the formation of a lava dome that covered Shirataniyama, ending about 10,000 years ago. Collapse of the dome produced pyroclastic deposits, and afterwards a landslide went SW from the summit (JMA, 2013).

Weekly volcanic activity reports

Preliminary and selective

Smithsonian/USGS weekly reports are selective and preliminary. They are not a comprehensive list of all eruptions or volcanic activity.

No weekly report appears on this page. Absence from the weekly report does not establish an absence of volcanic activity.

Historical catalogue records

Eruption history

Dates can be approximate, incomplete, or BCE. These are historical catalogue observations, not a statement about present activity.
