The effusive-explosive eruption of the volcano continues.
The extrusive actively lava dome continues to grow at moderate to high levels. This relatively intense effusive phase causes near-constant gravitational collapse of the lava dome triggering the block-and-ash flows (pyroclastic flows) that lifted ash plumes (so-called phoenix clouds) as it descended the slope.
A current volume of the growing lava dome has reached 4 million m³.
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.
