Ebisutoge-Fukuda tephra
Hyperconcentrated flow deposit, in the Ebisutoge-Fukuda tephra from Mie Prefecture, is thought to be deposited from dilution of the debris flow. Debris-flow deposit (facies A) is overlain by hyperconcentrated flow deposit (facies B). Typical hyperconcentrated flow deposit (facies B1;horizontal bedding Part) changes upward into diluted hyperconcentrated flow deposit (facies B2; scour and fill structure part). These facies characteristics indicate that the debris flow changed through hyperconcentrated flow into normal streamflow by dilution during flow traveling.
