[SVC41-P14] Volcanic activity at Asama volcano from the past data
Keywords:Asama volcano, number of erthquakes, type of erthquake, height of volcanic fume (volcanic fume index)
According to it, the eruption of 1973 and the eruption of 1982-1983 were different (Figure1). It is thought that this is due to the difference of eruption style of the magma eruption and the phreatic steam eruption. These results were compared recently (since 2002) eruption case and we will discuss about.
