From August 26 to August 27, 1883, the Indonesian volcanic island of Krakatoa, in the Sunda Strait, between the main Indonesian islands of Java and Sumatra, exploded in a cataclysmic explosive VEI-6 eruption. Two-thirds of the island collapsed and slid into the ocean as the volcano erupted and literally ripped itself apart, and this generated a 100-foot-high tsunami which devastated local areas and destroyed a lighthouse in the town of Anyer. It carried a Dutch naval vessel, Barouw, inland for over 5 km and left it stranded about 20 m above sea level. The tsunami itself did not propagate over trans-oceanic distances. What was noted on tide gauges around the world are considered to be the effect of the atmospheric pressure wave.
