The volcanic activity began in Dec 2021 and reached its climax nearly four weeks later. The eruption displaced 10 cubic kilometers of rock, ash, and sediment. The explosion was heard as far away as Alaska.

The eruption was phreatomagmatic, involving the interaction of water and magma, which caused explosive steam generation. The eruption produced a massive plume that reached a height of 58 kilometers, penetrating the mesosphere.

The volcanic aerosols released during the eruption had a temporary cooling effect on the Earth's surface by reflecting sunlight back into space.
