Geological summary

Hakusan is a complex andesitic-dacitic stratovolcano near the western coast of central Honshu. It was constructed over a high basement of sedimentary rocks in a region of very heavy snowfall that has contributed to erosional dissection. Holocene eruptions have consisted of phreatic or phreatomagmatic explosions from several summit craters. Partial collapse of the summit produced a debris avalanche down the E flank during the mid-Holocene. Eruptions were recorded over almost a thousand-year period until the 17th century.

From Wikipedia

Mount Haku , or Hakusan, is a dormant stratovolcano in Japan. It is located on the borders of Gifu and Ishikawa, on the island of Honshu. Mount Haku is thought to have first been active 300,000 to 400,000 years ago, with the most recent eruption occurring in 1659. Along with Mount Tate and Mount Fuji, it is one of Japan's "Three Holy Mountains" .
