Snow coverage on Mount Fuji from 2019 to 2022 is analyzed for monitoring its internal magma activities.
Image by FY-3D on May 4, 2022 showed 11.4 km2 of snow coverage on Mount Fuji.
Snow coverage on Mount Fuji was 28.8 km2 on May 8, 2019 and 10.58 km2 on May 10, 2021.
Average Land Surface Temperature at Mount Fuji was not higher in the first 10 days of May from 2020 to 2022. So the decreasing of snow coverage on Mount Fuji could possibly be caused by increasing activities of magma in it.
