[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.
