[SVC35-01] A working hypothesis for source craters and sequence of the 1707 Hoei eruption of Fuji Volcano, Japan
Keywords:Fuji Volcano, 1707 Hoei eruption, source craters, Hoei mound, eruption sequence, working hypothesis
On the basis of careful geomorphological and geological survey including SfM(Structure from Motion) technology with UAV photos, the strata exposed on the Akaiwa rock are revealed to be part of the proximal deposits of the Hoei eruption. Moreover, another NW-SE eruptive fissure is estimated to have opened between the Hoei mound and the Gotenniwa Higashi pyroclastic cone in the initial stage of the Hoei eruption and to have been buried by the subsequent eruptive deposits from the Hoei craters. The hypothesis of this fissure can resolve the problem thatlocation of a source crater of the basal pumice layer of the distal Hoei pyroclastic deposits is still unclear.
