Hot avalanches of material originated from the lava dome.
An explosive event began at 1653 on 16 June, producing an ash cloud 28 x 25 km in size that drifted NE.
The Aviation Color Code was raised to Red (the highest level on a four-color scale), but lowered back down to Orange about 5 hours later.
At 2110 the ash cloud was 212 x 115 km in size and drifting E; the leading edge of the cloud was about 245 km E.
