Surveillance cameras of volcanological observatory BPPTKG observed a massive pyroclastic flow at about 13:30 local time today that generated a dense dark ash plumes (so-called phoenix clouds) as can be seen in the attached video recorded below. The height of the ash plume is unknown and was not reported as visibility was very limited due to dense clouds. According to BPPTKG the glowing avalanches reached at about 3 km distance from the summit.
Gravitational collapse of the growing lava dome parts continues to generate the block-and-ash flows that descended the SW flank of the volcano in Kali Krasak and Kali Boyong direction.
