A visible glow and gas, steam and a small amount of ash emissions from satellite image on 3 May show fresh viscous magma rising into the lava dome within the summit crater.
Continuing magma accumulation into it made the lava dome prone to collapse resulting in a block-and-ash flow yesterday afternoon.
The pyroclastic flow traveled over the southwestern slope reaching length of 1,800 meters from the summit.
The event was detected on a seismic signal with maximum amplitudes of 27 mm and a duration of 149 seconds.
