White Island volcano (New Zealand): vent temperatures and gas emissions decreased, volcanic unrest continues

Scientists from the GeoNet volcano observatory did their regular flight over the volcano to measure gas emissions and the active vent temperature last week.

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.

Whakaari/White Island (New Zealand) - Smithsonian / USGS Weekly Volcanic Activity Report for 8 December-14 December 2021
GeoNet reported results from a 10 December overflight of Whakaari/White Island, noting a significant increase of temperatures at the active vent area. Temperatures in the main vent area were as high as 516 degrees Celsius, an increase from the range of 202-264 degrees Celsius measured in both September and November; temperatures over 500 degrees Celsius were last recorded during July-August. Very minor ash emissions continued to be visible with deposits only extending around the active vents. ... Read all
