This time, the build-up to the lava fountaining phase was very slow and started during yesterday, when strombolian activity restarted at the vent in the late evening, accompanied by a fluctuating but overall increasing tremor amplitude.
The activity continued to increase very gradually over night and picked up quickly in the early morning after around 4:20 am, reaching lava fountaining by around 8 am. The peak of the eruption occurred during 9-10 am, when tall lava fountains of 500-1000 m height produced an impressive eruption column that reached approx. 10 km altitude, producing a dense plume drifting into southeasterly direction.
As usual, activity stopped abruptly around 10:30.
