[SVC43-11] Holocene eruption history of Norikura Volcano, central Japan.
Keywords:volcanic eruption, tephra, active volcano, phreatic eruption, magmatic eruption, Hida Mountain Range
As a result, we distinguished two magmatic tephra eruptions and ten phreatic eruptions in Holocene. The tow magmatic tephra layers consist of scoria fall deposit with pyroclastic deposit and ash fall deposits, respectively. The latest eruption in the volcano is a phreatic eruption ca. 500 years ago. All the eruptions occurred from the craters around the Kengamine Peak.
The eruption frequency of the last 7,300 years is ca. 800 years / times, which is lower than the neighboring Yakedake volcano (ca. 300-100 years/times).
