Foreword : Special Volume on accurate eruptive history of Fuji Volcano, Japan, using trench survey

Abstract

We report the newly obtained results of eruptive history of Fuji Volcano, mainly using trench survey at the summit of a scoria cone. Compared with the stratigraphic study of summit eruptions of Fuji Volcano, that of flank eruptions has not obtained enough accurate eruptive history. The trench survey,however, is useful to study the accurate stratigraphy of flank eruption products, and samples for ¹⁴C carbon dating. In this volume, five papers are contained. Takada et al. is a report of the first trench survey of scoria cones on the southern flank of Fuji Volcano. Ishizuka et al. constructs the eruptive history of the north to western flank, and discuss the evolution of magma plumbing system of Fuji Volcano. Suzuki et al. is a report of the trench survey on the northwestern foot, including a topics of Omuro eruption. Nakano et al. reports the trench survey on the northeastern foot, and contains the evidences of distant eruption sites from the summit in Oshino village. Kobayashi et al. is a study on eruptive history of Fuji Volcano from AD 700 to AD 1,000 using stratigraphic correlation of KozushimaTenjosan tephra.
