The on-land ash flows entered into water in the Niigata region, transformed into water-saturated gravity flows, namely the SK110 and SK100 Tephras in the southwestern Niigata region, 100-150km from the source. The SK110 and SK100 Tephras Beds show similar tephra sequence and consists of two divisions as the primary subflow sets. The basal division A is sand-sized and the upper division B is mostly silt-sized. The division A shows very slight decrease along down flow both in thickness and grain-size especially in the SK110 Tephra Bed throughout the Niigata region of 100-200km from the source. The gradding and lamination in the division A of the SK110 Tephra Bed are also very slight, impling the nearly plug flow condition along 0.3\u00b0-0.1\u00b0 slope. In the division B of the SK110, water-escaped structures are occasionally found both in the Niigata and Akita regions of 450km from the source, impling the high-concentrated ash-cloud gravity flow origin. Thus, the division A and division B of the Om-SK110 Tephra comprise the bipartite flow deposit, and the SK100 Tephra is supposed to the similar mode of flowage. These bipartite flowage might be allowed to flow down so far as 450km from the source because of the least loss of the kinetic energy in the flow. Characterization of the parameters of these flows, comparing the case of  the Joetsu Ash of typical turbulent flow deposit, was also performed.", "subitem_description_type": "Abstract"}]},
