Sakurajima volcano (Kyushu, Japan): powerful vulcanian eruption

The eruption column from Sakurajima volcano on 11 April (image: @WeatherMonitors/x.com)

The explosive eruption at the volcano continues.

A vigorous vulcanian-sized eruption generated a copious ash plume rising to an altitude of 11,200 ft (3,400 m) that propagated to the south-southeast.

The warning bulletin states that ballistic impacts of volcanic bombs and pyroclastic flows could affect an area of about 2 km distance from the main crater.
