Two pyroclastic flows (hot avalanche of lava particles and ash) descended the southwestern flank of the volcano at 15:12 and 16:35 local time today, reaching approx. 2000 m distance from the summit. It resulted from a partial collapse of the growing active lava dome at the southwestern rim of the volcano's summit crater.
Ash plumes were separated from pyroclastic density currents (so-called phoenix clouds) that rose 600 meters above the crater.
Events were detected on a seismic signal with maximum amplitudes of 47 mm and 33 mm and a duration of 129 seconds and 155 seconds.
The public is being warned to stay at least 3 km away from the summit.
