A volcano in Kuchinoerabu Island, Kagoshima, Japan, erupted explosively and pyroclastic flows reached the coastal area on May 29, 2015. In this study, ALOS-2 PALSAR-2 data were used to analyze surface changes and deformations associated with the eruptive activity. The pyroclastic flows around the Shindake crater were observed by the differences of backscattering coefficients and the coherence values. Changed areas were extracted by a threshold value of the coherence, and were compared with a visual interpretation result conducted by the Geospatial Information Authority of Japan (GSI).
