Merapi volcano (Java, Indonesia): block-and-ash flows

The activity of the volcano continues at elevated levels.
Increased seismic activity during the past few days had been more frequent under the lava dome in the summit crater that produced a series of glowing avalanches from its flanks as we reported in the last update.
Expected dangerous hot pyroclastic flows occurred at 08:02 and 12:50 local time today likely as a result of gravitational collapse of the lava dome caused by more frequent volcano-tectonic earthquakes.
Block-and-ash flows continue to descend over the upper slopes towards Kali Krasak direction about 300 m long, phoenix clouds rose to estimated 10,170 ft (3,100 m) altitude as can be seen in the video recorded.
