Eruption of Kilauea on the Big Island of Hawai`i

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

Another explosive eruption of Mount Ruang in Indonesia

12 days after its powerful eruption on 17 April, 10-minute JMA Himawari-9 AHI Infrared Window (10.4 µm) images (above) showed another explosive eruption of Mount Ruang in Indonesia on 29 April 2024. The coldest cloud-top infrared brightness temperatures reached -90ºC (internal yellow pixels) at 1850 UTC, shortly after eruption onset. Note that the volcanic umbrella cloud exhibited concentric...
