The 1883 eruption of Krakatoa, a volcanic island in Indonesia, was one of the most powerful eruptions in recorded history, producing tsunamis and a sound heard thousands of kilometres away. Because no audio recording exists from that era, modern sound effects recreate the event from descriptions of its deep rumbles and explosive force. Creators now use these recreations in history lessons, documentaries and dramatic edits to make a distant nineteenth-century disaster feel immediate and tangible for viewers who have never experienced a major eruption.
