| Abstract;At Sakurajima volcano, debris flows at the Nojiri River have been generated frequently (15-40 times/year) since 1972 when eruptive activity was activated. The relationship of debris flows with rainfall and volcanic activity was examined, from a long-term viewpoint, using data on debris flows at the Nojiri River, volcanic ash and rainfall during the period from 1979 to 2002. Frequency of debris flows clearly decreased to 10 times or less/year since 1993 when the volcanic activity declined. (author abst.) |
