The answer to the question about the volcano that erupted in 1883 is not Krakatoa. It's actually Krakatau. The misspelling is a result of a mistake in the telegraph sent from the Dutch East Indies at the time.
Thank you for the response and it was listed as a possible answer since the beginning. Both Krakatau and Krakatoa are being used on scientific papers, so I choose the more internationally recognized one for the main answer.
