The volcano entered a violent eruptive episode today.

A couple of intense vulcanian-sized eruptions took place from the cinder cone generating grey-to-black ash-rich plumes. Released tephra rose to 700 m and 1100 m altitude and drifted NW and SW.

Surveillance cameras of the PVMBG volcano institute observed at about 17:30 local time constant ash emissions associated with a strong glow indicating a lava-fountaining phase (so-called paroxysm). Generating of hot, juvenile and plastic ejecta accompanied the process.

The seismic network reported seismic signals with maximum amplitudes of 60 and 70 mm and a duration of 89 and 335 seconds.

The strong eruptive activity at the volcano is currently dominated by vigorous vulcanian-type explosions over the past two days.
Several powerful blasts have continued from the cinder cone throughout this morning. The volcano generated a relatively tall (given the volcano's 189 m in height) and dense grey-to-black ash plume, rising up to nearly 3,1 km elevation at approx. 08:47 local time today. The plume dispersed towards the southwest.
The seismic network reported a seismic signal with a maximum amplitude of 75 mm and a duration of 56 seconds.
The warning bulletin states a 5 km exclusion zone around the main crater in place.

The strong eruptive episode (likely to be classified as paroxysm) is now in progress at the volcano's cinder cone.
After nearly 24 hours since the recent paroxysm phase, yet another such lava-fountaining episode took place at the volcano early this morning. At approx. 04:24 local time, strong lava jets could be seen in the PVMBG webcam, the height of fountains likely surpassed several hundreds of meters. The eruption was associated with continuous dense grey ash emissions that reached 2,2 km altitude and drifted northwest.
The seismic network reported a seismic signal with a maximum amplitude of 60 mm and a duration of 240 seconds.
The warning bulletin states a 5 km exclusion zone around the main crater in place.

Update 6/12:

The strong eruptive episode at the volcano continues at irregular intervals.
Surveillance cameras of the PVMBG volcano institute observed at 14:31 local time yesterday an intense explosion from the volcano's cinder cone that generated a perpendicularly rising grey-to-black ash-abundant column to estimated 1.6 km height drifting northwest. 3,5 hours later, another powerful eruption took place from the cinder cone, spewing a perpendicular grey-to-black ash-rich plume again, but a way higher than the previous event this time. The spectacular ash plume volcano rose up to nearly 3,7 km elevation and dispersed towards the northwest. Given the volcano's low height (189 meters), today's plume is among the highest ones of the recent year at the volcano.
Last night, about 30 minutes after midnight, erupting incandescent lava jets (paroxysm) were being detected from the cone via the webcam. Pyroclastic material in the form of hot, juvenile and plastic ejecta is distinguishable in the webcam screenshot as being landed onto the flank of the volcano.
The seismic network reported seismic signals with maximum amplitudes of 70 and 65 mm and durations of 169, 157 and 436 seconds.
The warning bulletin states a 5 km exclusion zone around the main crater in place.
