Note (General): Red soil (local name: kunigami-maji) is a red to yellow soil that is easily washed away by rain when on a bare surface. Since the 1960s, a large amount of red soil in the northern part of Okinawa Island was washed out and deposited on the coral reefs as a result of land use changes. In this study, using the Advanced Land Observing Satellite (ALOS) Advanced Visible and Near Infrared Radiometer type 2 (AVNIR-2) data for monitoring red soil sedimentation in the coral reefs were examined. In the Minna area, the ranges of green to near infrared bands of AVNIR-2 data were as same as or wider than those of TM data, but the range of blue band of AVNIR-2 data was narrower than that of TM data. These relations were also observed in the Katabaru area. The results suggest that the sensitivity of the blue band sensor of AVNIR-2 would differ from that of TM. However, it would not be fatal to monitoring red soil in the coral reefs.
