Whakaari/White Island (New Zealand) - Smithsonian / USGS Weekly Volcanic Activity Report for 8 December-14 December 2021
Ср, 15 дек 2021, 06:42 06:42 AM | АВТОР: VNGeoNet 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.
Gas emissions had possibly decreased, though measurements had not been taken since 18 November. The water in the lake has receded likely due to recent weather conditions. The Volcanic Alert Level remained at 2 and the Aviation Color Code remained at Yellow.
