What volcano exploded in 1883 with the force of 200 megatons of TNT?

The eruption has been assigned a rating of 6 on the Volcanic Explosion Index and is estimated to have had the explosive force of 200 megatons of TNT. (For purposes of comparison, the bomb that devastated Hiroshima had a force of 20 kilotons, nearly ten thousand times less explosive as the Krakatoa eruption.

The 1883 eruption of Krakatoa (Krakatau) in the Dutch East Indies (now Indonesia) began on the afternoon of Sunday, 26 August 1883 (with origins as early as May of that year), and peaked on the late morning of Monday, 27 August 1883, when over 70% of the island and its surrounding archipelago were destroyed as it collapsed into a caldera. Additional seismic activity was reported to have continued until February 1884, though reports of seismic activity after October 1883 were later dismissed by Rogier Verbeek’s investigation into the eruption. The 1883 eruption was one of the deadliest and most destructive volcanic events in recorded history. At least 36,417 deaths are attributed to the eruption and the tsunamis it created. Significant additional effects were also felt around the world in the days and weeks after the volcano’s eruption.
