Mount Erebus is the second highest and most active volcano of Antarctica. It is also the southernmost active volcano on Earth.

Summary

[edit]
Description
English: Mount Erebus is the second highest and most active volcano of Antarctica. It is also the southernmost active volcano on Earth. Its summit temperature averages between -20°C during the summer and -50°C in winter, for this reason, despite the volcanic activity, it remains covered by glaciers. At the centre of the volcano’s summit, there is a deep crater which contains two lava lakes famous for their active strombolian activity. This image acquired by one of the Copernicus Sentinel-2 satellites, shows a rare cloud-free view of the summit of Mount Erebus in which the lava lakes are clearly visible. The Copernicus Sentinel-2 constellation (Sentinel-2A and Sentinel-2B) plays an important role in monitoring volcanic activity thanks to the Short Wave InfraRed channels that are included amongst the 13 spectral bands of the Multispectral Instrument onboard these two satellites. The high spatial resolution and the high average revisit time (5 days at the equator) allow to monitor different volcanic processes and improve hot-spot detection techniques.
