The Kanlaon Volcano in the Philippines erupted at 0703 UTC on 9th December 2024. JMA Himawari-9 Air Mass RGB images from 0650-1500 UTC (above) — created using Geo2Grid — showed the volcanic cloud as it drifted westward across the Sulu Sea. This volcanic cloud was primarily composed of SO2 (along with some ash), and exhibited shades of orange in the RGB images. The “Red” component of the Air Mass RGB uses the 7.3 µm spectral band, which is sensitive to SO2 absorption — for example, see this blog post.
