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... Read More
The distinct hot thermal signature (black to yellow to red pixels) of a new fissure eruption between Stóra-Skógfell and Sýlingarfell on the Reykjanes Peninsula in southwestern Iceland was apparent in 10-minute Full Disk scan GOES-16 (GOES-East) Shortwave Infrared (3.9 µm) images during the 20th-24th November 2024 period (above). Station identifier BIRK is Reykjavik Airport, and... Read More
A prolonged eruptive period of Popocatépetl occurred during 23-30 October 2024. An animation of GOES-16 (GOES-East) Nighttime Microphysics RGB + daytime True Color RGB images from the CSPP GeoSphere site (above) displayed the volcanic plumes — which often exhibited brighter shades of magenta at night, and a hazy appearance during the day —...

5-minute PACUS Sector GOES-18 (GOES-West) Shortwave Infrared (3.9 µm) images (above) showed the thermal anomaly (heat signature) following the onset of an eruption of Kilauea on the Big Island of Hawai`i — which began around 1030 UTC on 03 June 2024. The peak 3.9 µm brightness temperature sensed at the eruption site was... Read More
