Sakurajima within Aira caldera is producing a gas plume to the NE in this November 2020 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 43 km across). The 17 x 23 km caldera formed about 29,000 years ago during the eruption of around 98 km³ of pumice and 300 km³ of pyroclastic flows. In recent times the main epicenter for activity is Sakurajima that has since formed in Kagoshima Bay and is seen here with a weak gas plume dispersing NE to E.
