Krakatoa video
Krakatoa explodes: In the afternoon of 17 Oct, a particularly violent explosion occurred at Anak Krakatau, blasting away a portion of the southern crater rim. A similar event might have been the final trigger for the catastrophic landslide that let the cone collapse and cause a devastating tsunami on 22 Dec 2018.

Eruption from close: On 17 Oct, explosions were particularly violent at Anak Krakatau. We show a series of images of a spectacular explosion captured from close range by boat.
