SATELLITE ANALYSIS OF VOLCANIC CLOUDS AND TRANSPORT OF ACIDIC SUBSTANCES FROM MT. ASO AND MT. SAKURAJIMA

摘要

The satellite images of volcanic clouds in Kyushu, Japan during September-November 1989 were studied in connection with the mountain site measurement of atmospheric qualities at Unzen-Nodake and the SO_2 concentration data at Aso Volcano Museum. The images strongly indicate that many high concentration events of SO_2 were the results of the long-range transport of volcanic gas from Mt Aso and Mt Sakurajima to these stations. Brief comments on the 2000 eruption of Miyake-jima volcano are added.
