Another video, taken by a camera at a nearby observatory, shows what the eruption looked like from the coast. This one doesn’t have as much action as the first one, although you can make out the plumes of smoke.

Anak Krakatau means “Child of Kratakau,” a reference to the fact that it emerged from the caldera of the famous Krakatau volcano. In 1883, Krakatau erupted and caused global devastation, killing 36,000 people. According to Volcano Discovery, the majority of people died because of the huge tsunamis triggered by the eruption. In addition, the eruption also triggered a period of global cooling.
