GOES-18 (GOES-West) Dust RGB images (above) showed a plume of resuspended volcanic ash (brighter shades of pink) from the 1912 Novarupta-Katmai eruption in Alaska, which was being transported offshore across the Shelikof Strait (and Buoy 46077, where the peak wind gusts were 31 knots) toward Kodiak Island on 10 October 2023. Surface ash within the Valley Of Ten Thousand Smokes was being lofted by a... Read More

GOES-18 (GOES-West) SO2 RGB and Ash RGB images (above) showed the complex transport of a volcanic cloud produced by an explosive eruption of Mount Shishaldin that began around 1350 UTC on 03 October 2023. The bulk of the higher-altitude volcanic cloud was rich in SO2 (shades of yellow in both RGB types), while a smaller mid-level portion that had... Read More

1-minute Mesoscale Domain Sector GOES-18 (GOES-West) Dust RGB images (above) showed a plume of resuspended ash (brighter shades of pink) from the 1912 Novarupta-Katmai eruption in Alaska, which was being transported offshore across the Shelikof Strait toward Kodiak Island on 27 September 2023. Surface volcanic ash within the Valley Of Ten Thousand Smokes.was being lofted by strong northwesterly winds.Volcanic ash (VA)... Read More
