13 Sep new Zealand volcano white island was thrown into the post ash plume which spread to the North-East at a distance of 50 km. In connection with the increase of eruptive activity, hazard status of the volcano was raised from the first to the third level.
The eruption occurred from the acidic lake and is according to volcanologists, is a sign of destabilization of the hydrothermal system.
Ash emission occurred suddenly, although recently, volcanologists have conducted measurements of the acid level in the lake and did not notice any changes, except for a small decrease in the water temperature.
