GOES-16 Shortwave Infrared (3.9 µm) images, from 0730 UTC on 14 January to 1810 UTC on 14 January [click to play animated GIF | MP4]

A distinct hot thermal signature (black to yellow to red pixels) of the Hagafell-Grindavik fissure eruption in southwestern Iceland was apparent in GOES-16 (GOES-East) Shortwave Infrared (3.9 µm) imagery on 14 January 2023 (above). Station identifier BIRK is Reykjavik Airport, and BIKF is Keflavik International Airport.

Since the fissure eruption and subsequent lava flows began during the nighttime hours, the thermal signature also showed up well in GOES-16 Near-Infrared 1.61 µm and 2.24 µm imagery (below).
