抄録
Small-scale pyroclastic flows due to the collapse of the lava dome have been frequently generated during the 1991-93 eruption of Unzen Volcano. We have recorded video footages which show the generation of pyroclastic flows during January-March 1992. Two types of phenomena have been observed : deformation of the lava dome due to flowage ; and a sudden discharge of gas and ash through fractures and peeling-off of rock fragments from the surface of cooling lava blocks. Pyroclastic flows were generated only in places on the lava dome where these precursory phenomena were frequently observed.
