Merapi volcano (Java, Indonesia): glowing rockfalls continue

The extrusive activity at the volcano continues.

Glowing avalanches (hot avalanches of lava particles and ash) descended the southwestern flank of the volcano at 20:26 local time tonight, reaching approx. 2700 m sliding distance from the summit. It resulted from growing, more and more unstable hot lava material, accumulating in the active lava dome at the southwestern rim, making it prone to collapse into hot rock falls.

Ash plumes were separated from pyroclastic density currents (so-called phoenix clouds) that rose above the crater.

The public is recommended to stay at least 3 km away from the summit.
