The maximum vent temperature was measured at about 191 °C, which was a decline from 516 °C detected in December last year. Temperatures over 500 °C were being observed in July and August 2021.
The gas measuring flight confirmed a minor decrease of volcanic gases (SO2, CO2) compared to December values. Near-constant degassing is related to magma batch saturated by volatiles within the volcano edifice.
Ash emissions continue at the vent.
Volcanic Alert Level remains at level 2 and the Aviation Colour Code remains at Yellow.
