Keywords:active volcano, pyroclastic flow, stratigrahy

Pyroclastic flows occurred at many times during formation of lava dome on the Heisei eruption of Mt.Unzen. There were some studies of pyroclastic flows on Mt. Unzen (Kobayashi and Kato, 1985). After the Heisei erupyion many studies reported about it (Kobayashi and Nakada, 1991, Watanabe and Hoshizumi, 1995). It is important about understanding the characteristics of the volcano from the past activities. In this study, the pyroclastic deposits and the stratigraphy 150ka on Mt.Unzen be reported.
