JMA Hmawari-8 True Color RGB images created using Geo2Grid (above) showed the southwestward-moving volcanic cloud associated with an eruption of Semeru –located at the center of the images — in East Java around 0750 UTC on 04 December 2021. Due to the high water and ice loading within upper portions of the... Read More
Imagery from the NOAA/CIMSS Volcanic Monitoring website (link) shows derived Ash loading (above) from the 3 November eruption of Karymsky on the Kamchatka peninsula. The website identified an eruption beginning around 0720 UTC, with an obvious eruptive plume by 0740 UTC. In addition to Ash Loading, shown above, Ash Height... Read More
GOES-16 (GOES-East) True Color RGB images created using Geo2Grid (above) showed the east-southeastward drift of ash-laden volcanic clouds from Cumbre Vieja on La Palma in the Canary Islands on 02 November 2021. Since this current eruptive period began on 19 September, intermittent periods of volcanic clouds with an elevated ash content have been observed... Read More
