The eruptive activity at the volcano remains elevated.
Since the last update, about 15 explosive events have occurred from the cinder cone and is highly likely that intense powerful explosions are continuing even at the time of this update.
At about 22:41 local time yesterday, the surveillance camera observed a short but violent eruptive episode, known as paroxysms, generating dome-shaped columns of juvenile lava material from the cinder cone. The lava-fountaining sequence lasted only 31 seconds. Whether the eruption produced a new lava flow or not is unclear yet until the satellite passes over the volcano and reveals some new thermal anomalies hinting lava flow emissions, if so. A couple of minutes later, at 22:46 local time, another brief paroxysm (90 seconds) took place from the crater, releasing typical incandescent lava bombs.
Following paroxysm episodes, there have been several more eruptions producing grey-to-black thick ash columns rising up to 1,100 meters and 1,600 meters, respectively.
There might have been a couple more paroxysm events throughout the day, but since glow, presumably the best indicator of new fresh magma and even paroxysm, is not well visible during daylight, it’s difficult to identify such events.
The warning bulletin states a 5 km exclusion zone around the main crater in place.
