The past week  at Sakurajima (from April 2 to 6, 2020) the eruptive activity actively continued.

JMA reports up to 15 eruptions on April 4 at the Minamidake crater, with block ejections at 600-900 meters, and according to an alert bulletin, could reach up to 2 km., and plumes reaching 3,800 m. altitude.

Night glow is observed.

Seismicity is dominated by numerous volcanic earthquakes.

The inclinometers and extensometers indicate that the volcano is raised (inflation) and widened, signs of a continuous feeding.
