GOES-16 (GOES-East)<\/em> True Color RGB images created using Geo2Grid<\/strong><\/a> (above)<\/strong><\/em> showed the south-southeastward drift of an ash-laden volcanic cloud from Cumbre Vieja<\/strong><\/a> on La Palma in the Canary Islands on 09 October 2021. Since this most recent ongoing eruptive period began on 19 September<\/strong><\/a>, intermittent periods of volcanic clouds with an elevated ash content have been observed — and on this day, the darker tan to light brown appearance was an indication that higher ash concentrations were likely.     <\/p>\n

In the corresponding GOES-16 Ash RGB<\/strong><\/a>  images (below),<\/strong><\/em> increasing shades of pink — which suggest a higher ash content — became apparent within a semi-circular volcanic cloud element after 1100 UTC.  <\/p>\n

GOES-16 retrieved products from the NOAA\/CIMSS Volcanic Cloud Monitoring<\/strong><\/a> site (below)<\/strong><\/em> indicated that the more distinct pulse of ash-laden volcanic cloud had a maximum height in the 5-6 km range, and was composed of ash particles having an effective radius 10 \u00b5m and smaller.  <\/p>\n
