Abstract
Long-term eruption rates of 18 Quaternary volcanoes in Japanese islands are estimated to range from 5 to slightly greater than 0.05 km 3/10 3 y. The long-term rate correlates well with the variation of phenocryst assemblage, which reflects the crystallization temperature. The long-term eruption rate and temperature of magma from the volcanoes in northeastern Japan are higher than those in southwestern Japan. In northeastern Japan, the long-term rate is higher at volcanoes located near the colcanic front than those on the back-arc side. Applying the estimated long-term eruption rates to the model calculation of continuous magma supply, the appropriate radius of the magma chamber is estimated to be less than 3.5 km.
