The activity of the volcano remains essentially unchanged characterized by the actively growing lava dome.
Collapsing parts of the dome triggered several block-and-ash flows caused by gravitational collapse of the lava dome. Rockfall avalanches traveled over the southwestern slopes about 2 km distance from the summit and lifted ash plumes separating from the avalanches (so-called phoenix clouds).
Pyroclastic flows - turbulent and hot avalanches of hot lava rocks, ash and volcanic gasses mixed together - are being released from the growing dome.
The volcano observatory counted about 270 earthquakes on 15 June.
The volcano's official alert level remains at 3 (on a scale of 1-4), and the public is being warned to stay at least 5 km away from the summit.
