The intense activity of the volcano continues.
Large glowing avalanches continue to be observed detaching from the southwestern lava dome at roughly frequent intervals of 5 to 10 minutes, Andi reported. A sliding distance usually has reached approx. 2 km length descending to the base of the edifice.
Therefore, risk of yet another dangerous, turbulent hot avalanche of lava rock fragments of all sizes embedded in a mixture of turbulent gas and ash racing down slopes remains high.
The alert level for the volcano remains at Level 3.
