The extrusive eruption of the volcano persists at heightened levels.
The active southwestern and southeastern lava domes continue to grow as viscous magma rises into and pilling up there. Unstable, loose lava material makes both lava domes prone to partially collapse. Therefore, accumulated and large dome blocks tend to undergo gravity and turn into tumbling hot incandescent rock falls, emanating from the lava dome, and race over steep slopes down the edifice. Ash plumes and dust separating from block-and-ash flows, so-called phoenix clouds, accompany pyroclastic flows.
The PVMG volcano observatory reported a seismic signal with a maximum amplitude of 55 mm and a duration of 156 seconds today.
The alert status remains at Level 3 since November 2020.
The public is being warned to stay at least 3 km away from the summit. The current hazards are hot avalanches that can become mobilized into hot glowing currents (pyroclastic flows), especially towards the south-southwest sector including Kali Kuning, Boyong, Bedog, Krasak, Bebeng, & Putih with a maximum distance of 5-7 km. Pyroclastic flows are deadly, turbulent, ground-hugged hot avalanches of lava rock fragments of all sizes embedded in a mixture of turbulent gas and ash racing down slopes.
