The distinct hot thermal signature (black to yellow to red pixels) of a new fissure eruption between Stóra-Skógfell and Sýlingarfell on the Reykjanes Peninsula in southwestern Iceland was apparent in 10-minute Full Disk scan GOES-16 (GOES-East) Shortwave Infrared (3.9 µm) images during the 20-24 November 2024 period (above). Station identifier BIRK is Reykjavik Airport, and BIKF is Keflavik International Airport. The fissure eruption began at 2314 UTC on 20 November, with the first GOES-16 thermal signature appearing at 2320 UTC.

A 30-meter resolution Landsat-9 Natural Color image (source) provided a detailed view of the lava flow’s hot thermal signature (brighter shades of red) at 1252 UTC on 24 November (below). A hazy volcanic plume could be seen drifting to the south-southwest.
