Whakaari/White Island volcano (North Island, New Zealand) - Smithsonian / USGS Weekly Volcanic Activity Report for 12 January-18 January 2022 (Continuing Activity)

On 18 January GeoNet reported results from an overflight of Whakaari/White Island the week before, noting a significant decrease of temperatures at the active vent area and a small decrease in gas emissions. Temperatures in the main vent area were as high as 191 degrees Celsius, a decrease from a high value of 516 measured in December. Gas emissions had slightly decreased since December; both sulfur dioxide and carbon dioxide gas emission rates were slightly below the 10-year average.
Both the gas-emission and temperature data were consistent with a degassing magma body below the surface. Very minor ash emissions continued to be visible with deposits only extending around the active vents. The water in the lake had receded likely due to recent dry weather conditions.
The Volcanic Alert Level remained at 2 and the Aviation Color Code remained at Yellow.
