Fogo eruption (Cabo Verde)
Fogo volcano in the Cape Verde Islands erupted on 23 November 2014. First indication from satellite (SEVIRI) was made at 11:30 UTC. SO2 was detected from AIRS and SEVIRI with an initial estimate of ~14 kt (SO2). No ash was detected by either AIRS or SEVIRI, probably because of the large pixel size and small amount of ash emitted. SEVIRI detected SO2 using an algorithm developed by Prata and Kerkmann (2007) based on the 8.6 µm channel (see animation).
