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. Historical eruptions were recorded over almost a thousand-year period until the 17th century.
