Anak Krakatau: collapse and regrowth of a volcano since 2018

The animated gif compiled from Sentinel-1 radar images shows the evolution of Anak Krakatau volcano since late 2018 when most of its summit cone collapsed, triggering a deadly tsunami. In the months and years after this event, continued activity has been filling the initial crater lake and is now in the process of growing a new cone in its place.
