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...

10-minute JMA Himawari-9 AHI Infrared Window (10.4 µm) images (above) showed an explosive eruption of Mount Ruang in Indonesia on 17 April 2024. Note that a thunderstorm was reported at Menado (station identifier WAMM) from 1400-1430 UTC, due to abundant lightning activity within the dense volcanic umbrella cloud.In the Himawari-9 Infrared Window...
