This picture, acquired by PRISMA on December 8th 2021, shows the Erebus volcano in Ross Island (Antarctica), in a pansharpening of a short-wave infrared (SWIR) processing. Erebus is the most southern active volcano on Earth.
Reddish colours indicate points at higher reflection (or emission) in bands of the electromagnetic spectrum that are closer to the thermal infrared. In the lower (southern) side of the picture it is possible to notice the hot volcanic caldera.
It is also possible to notice the different SWIR trace of the flanks of the volcano exposed to the direct sunlight (towards north and northeast) compared to the ones exposed to the shadow (towards south and southwest), even if without the ice cover in both cases.
