Strong lava fountaining and effusion of lava flows continue at similarly high levels as during the past days, along with the generation of an ash plume that rises approx. 2 km and drifts southeast.
Yesterday afternoon, a portion of the southwestern crater area collapsed, effectively creating an elongated depression where the summit vents are aligned. A flood of lava poured onto the western flank as a result, and for some time, the lower vent (the one that formed 10 days ago on the SW flank) produced violent dome-shaped liquid lava fountains.
Later on, this vent decreased the fountaining activity, while one of the adjacent higher summit vents began to produce pulsating, very tall lava fountains reaching approx. 500-600 m:

The effusive vent beyond the NW foot of the cone seemed to have decreased its activity a lot, perhaps due to crusting over and tunneling of the lava flow.

Volcanic tremor remains stable at high levels. Earthquakes have increased in number and average size. During the past 24 hours, there were 22 quakes of magnitudes 3.0-3.7, many of them felt in the area. Additionally, 44 quakes between 2.0 and 3.0. occurred, while there are probably hundreds of smaller quakes as well that cannot be detected within the signal dominated by the tremor.
All in all, the situation remains tense, and it's impossible to predict what will happen next.
