GOES-16 Shortwave Infrared (3.9 µm) images, from 0550 -1610 UTC on 08 February [click to play animated GIF | MP4]

A distinct hot thermal signature (black to yellow to red pixels) of a new Sundhnúkagígar fissure eruption on the Reykjanes Peninsula in southwestern Iceland was apparent in GOES-16 (GOES-East) Shortwave Infrared (3.9 µm) imagery on 08 February 2024 (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).
