A new eruption started at the Anak Krakatoa, or Krakatau, volcano on Rakata Island in Indonesia on 3 February 2022, as seen in this image captured by the Copernicus Sentinel-2 mission. The eruption prompted the Anak Krakatau Volcano Observatory to raise the aviation colour code to orange.

The eruption started at around 16:15 local time, with a thick column of gas, with possible volcanic ash content, rising to around 200 m above the crater.
