1883 eruption of Krakatoa

Between 19 May and 21 October 1883, the volcanic island of Krakatoa (located in the Sunda Strait, then part of the Dutch East Indies—modern-day Indonesia) began erupting, lasting more than five months. On 27 August, the island had its most significant eruption, which destroyed over 70% of the island and its surrounding archipelago, the island collapsing into a caldera.
