Heavy rains in recent years, represented by the western Japan region in July 2018, the Kanto region in September 2019, and the Kyushu region in July 2020, occur almost every year. The Remote Sensing Society of Japan is working on immediate disclosure of the damage situation using satellites and aircraft in the event of such a disaster. However, in most cases, land is the priority for such efforts. Therefore, even if there is a serious impact on the aquaculture industry, little is known about the damage situation in coastal waters and changes in the water quality environment. On the other hand, in recent years, the GCOM-C SGLI sensor with 250 spatial resolution and Himawari-8 AHI sensor with 2.5-minute observation cycle increase the possibility of coastal surveillance in the event of a disaster. Therefore, in this presentation, I will introduce the development of a disaster turbidity monitoring method using both SGLI and AHI sensors in order to monitor the outflow route of seafloor sediments during a disaster.
