The 1883 eruption of Krakatoa in the Dutch East Indies (now Indonesia) began in the afternoon of August 26, 1883 (with origins as early as May of that year), and culminated with several destructive eruptions of the remaining caldera. On August 27, over 70% of the island and its surrounding archipelago was destroyed by the explosive eruption. Additional seismic activity was reported until February 1884, though reports after October 1883 were later dismissed by Rogier Verbeek's investigation. The 1883 eruption was one of the deadliest and most destructive volcanic events in recorded history, with at nearly 40,000 deaths being attributed to the eruption itself and the tsunamis it created. Significant additional effects were also felt around the world.
