Overview
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.

About the Photo
Hakusan, seen here from the WNW, contains multiple vents along a roughly N-S line. 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. Eruptions were recorded over almost a thousand-year period until the 17th century.
