Glowing avalanches continue to occur from the active dome, which actually grows in two relatively independent parts to the SW and SE, as our correspondent and volcano guide Galih reported.

According to official information, the volume of the lava dome in the southwest sector is 840,000 m3 with a growth rate of 12,900 m3 / day. The morphological analysis of the peak area based on photos from the southeast sector on March 18, 2021 shows the height of the central dome is 65 m, and the estimated volume of the dome is 950,000 m3 with a growth rate of 12,800 m3 / day since January 4, 2021.
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 km.
In addition, the eruption of volcanic material in the event of an explosive eruption could reach a radius of 3 km from the summit.
