GOES-18\u00a0(GOES-West)<\/em>\u00a0SO2 RGB<\/strong><\/a> images (above)<\/strong><\/em> showed the eastward drift of a volcanic cloud produced by an explosive eruption of Mount Shishaldin<\/strong><\/a> that began around 0150 UTC on 16 September 2023. Trace amounts of ash fall were observed at False Pass from 0200-0430 UTC.<\/p>\n

GOES-18 True Color RGB images from the\u00a0CSPP GeoSphere<\/strong><\/a>\u00a0site\u00a0(below)<\/strong><\/em> helped to highlight the ash-laden volcanic cloud (light shades of tan) moving east from the summit of Shishaldin.<\/p>\n
