The extrusive actively lava dome continues to grow at moderate to high levels triggering the incandescent avalanches (block-and-ash flows) caused by gravitational collapse of the lava dome that traveled over the E-SE and S slopes about 500 m-1,500 m distance from the summit. Collapsing parts of the flow generated a small avalanches that lifted ash plumes (so-called phoenix clouds) as it descended the slope.
Emissions of water vapor and gases rose 164 ft-984 ft (50 m-300 m) above the summit and drifted into various directions, but most often E-SE direction.
The warning bulletin states that ballistic impacts of volcanic bombs and pyroclastic flows could affect an area of about 3 km distance from the main crater and 5 km on the SE flank and 4 km on the NE flank.
