| Abstract | Magnetic properties were investigated using samples taken within a few days after eruption events through the latest eruption at Unzen Volcano, Kyushu Japan, with additiorlal lava and bomb samples taken a few years after the events. Natural remanent magnetization, Curie temperature, coercive force, coercivity of remanence and remanent saturation magnetization imply occurrence of four periodical changes, showing temporal increase within each period superposed with gradual increase throughout the whole period of the eruption. One of the boundaries of the four periods is supported by the petrological study on the same samples taken within a few days(Nakada and Motomura,1999), which reflected two pulses of lava effuSlon rate. |
