The eruption continued with no significant changes today, although the visible and audible intensity tended to decrease. The lava fountain from the summit vents was more pulsating and less intense, but still produced a lot of ash, which formed a plume that rose 2-3 km and drifted in westerly directions.
The lower vent on the middle of the cone's southwestern slope, which had been the site of abundant lava emission in the past week, was again more active today. Most of the time, it was producing a liquid fountain sometimes tens of meters high and feeding a channeled lava flow visible traveling towards Tacande, but following the same path as previous ones.

Volcanic tremor remains at steady high levels with no significant variations, suggesting that the effusion rate of magma remains high; much of the lava erupted probably is going directly into lava tubes in order to feed the lava flows further downslope, and invisible in the vent area.
Earthquake activity remains elevated, with frequent tremors around magnitudes of 3 at 10-15 km depth beneath the volcano's summit.
