Geonet's instruments inside White Island covered with ash from the eruption on 27 April 2016 (image: Geonet)A small phreatic explosion occurred inside the main crater of the volcano on the evening of 27 April around 21:50 local time, Geonet reported. The volcanic alert level was raised to 3 and aviation color code to Orange.
Since the eruption, the volcano has returned to quiet / normal activity and the alert level was again lowered to 2 (although aviation color code remains orange for the time being as other explosions could occur).
The eruption covered about 80% of the crater's surface and the northern and southern crater walls with fine ash. It had been preceded by a slight increase in seismic activity, but SO2 gas emissions had been unchanged. During a visit last week, it had been observed that the level of the acid crater lake had fallen by approx. 2 meters, indicating significant evaporation, and / or greater infiltration.
