JMA Himawari-9 False Color RGB images from the NOAA/CIMSS Volcanic Cloud Monitoring site (above) showed plumes of SO2 (brighter shades of cyan) drifting northward, westward and southeastward from the East Epi submarine volcano, following its eruption on 01 February 2023 (local time).  The differences in SO2 transport were due to directional wind shear with height. No signatures of significant concentrations of volcanic ash were seen in other types of multispectral satellite imagery.
