Description :
Sediment discharge including debris flows generated by storm runoff during, or just after volcanic eruptions can bring about severe disasters downslope on the flanking alluvial fans. In many cases, the main cause of such disasters is a major change in the hydrologic response of the slope from the eruption. Observation of sediment discharge at 3 volcanic torrents at Mount Unzen and Mount Yakedake in Japan, and Mount Merapi in Indonesia, provided insight to such processes at volcanoes with recent eruption histories.
