The effusive eruption of the volcano continues from all fissure vents. The activity continued at stable levels over the past days until it began to fluctuate yesterday.

Starting around 01:00 local time tonight, the spatter cone started to erupt taller-than-usual lava fountains of up to perhaps 300 m height characterized by regular pulsating at intervals of 7 to 10 minutes.
Emissions of gas and steam plumes were dispersed about 300 m to the southwest of the eruption site.
The reason of this change in the activity is not clear yet, but the discharge rate of this eruption seems rather higher compared to most previous eruptions of the eruption site likely caused by magma/gas composition change at shallow level.
