Klyuchevskoy volcano blows steam ring, eruption 20-21 April 2020

Time-lapse of Klyuchevskoy volcano seen from the webcam in Klyuchi village, during the night and morning of 20-21 April 2020. The lava flow on the (hidden in view) SE flank illuminates the steam and ash plumes at night. At the end of the video, the volcano emits a large steam ring ("smoke ring"), a ring vortex created by a sudden pulse of gas emission through a circular vent.
