[AHW35-P06] Runoff processes of volcano springs in the northeast foot of Mt. Ontake

*Kazuyoshi Asai1 (1.Geo-Science Laboratory)

Keywords:Volcano springs, Mt. Ontake, Runoff-processes

Hydrological observation and sampling of the spring were carried out at the northeast foot of Ontake volcano. Stable isotope ratio and concentration of transient tracer (CFCs, SF6) were measured in Geo-science laboratory. Based on the results, we discuss the runoff-processes of the springs with short residence time less than 10 years.
